data sheet 6 rev. 1.1, 2014-04-23 tle7250gvio functional description 4 functional description can is a serial bus system that connects microcontrollers , sensors and actuators for re al-time control applications. the use of the c ontrol a rea n etwork (abbreviated can) within road vehi cles is described by the international standard iso 11898. according to the 7-layer osi reference model, the physical layer of a can bus system specifies the data transmission from one can node to all other available can nodes within the network. the physical layer specification of a can bus system includes all electrical and mechanical specifications of a can network. the can transceiver is part of the physical laye r specification. several diffe rent physical layer standards of can networks have been developed in recent years. the tle7250gvio is a high speed can transceiver without a dedicated wake-up function. high-speed can tr ansceivers without a wake-up function are defined by the international standard iso 11898-2. 4.1 high speed c an physical layer figure 3 high speed can bus signals and logic signals v cc can_h can_l txd v io = digital supply v cc = high speed can power supply txd = input from the microcontroller rxd = output to the microcontroller canh = voltage on the canh input/output canl = voltage on the canl input/output v diff = differential voltage between canh and canl v diff = v canh C v canl rxd v diff dominant recessive v io v io t t t t v diff = iso level dominant v diff = iso level recessive
tle7250gvio functional description data sheet 7 rev. 1.1, 2014-04-23 the tle7250gvio is a high speed can transceiver, oper ating as an interface between the can controller and the physical bus medium. a hs can network is a two-wire, differential network, which allows data transmission rates up to 1 mbps. the characteristics of a hs can networ k are the two signal states on the can bus: ?dominant? and ?recessive? (see figure 3 ). the canh and canl pins are the interface to the can bus and both pins operate as an input and output. the rxd and txd pins are the interface to the microcontrolle r. the txd pin is the serial data input from the can controller, and the rxd pin is the serial data output to the can controller. as shown in figure 1 , the hs can transceiver tle7250gvio includes a receiver and a transmit ter unit, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. the hs can transceiver tle7250gvio converts the serial data stream avail able on the transmit data input txd, in to a differential output signal on the can bus, provided by the canh and canl pins. the rece iver stage of the tle7250gvio monitors the data on the can bus and converts them to a serial, single-ended si gnal on the rxd output pin. a logical ?low? signal on the txd pin creates a ?dominant? signal on the can bus, followed by a logical ?low? signal on the rxd pin (see figure 3 ). the feature of broadcasting data to the can bus and listening to the data traffic on the can bus simultaneously is essential to support the bit-to-bit arbitration within can networks. the voltage levels for hs can transceivers are defi ned by the iso 11898-2 and the iso 11898-5 standards. whether a data bit is ?dominant? or ?recessive? depends on the voltage difference between the canh and canl pins: v diff = v canh - v canl . in comparison with other differential netw ork protocols, the differential signal on a can network can only be larger than or equal to 0 v. to transmit a ?dominant? signal to the can bus, the differential signal v diff is larger than or equal to 1.5 v. to receive a ?recessive? si gnal from the can bus, the differential v diff is smaller than or equal to 0.5 v. ?partially-supplied? high speed can networks are thos e where the can bus nodes of one common network have different power supply conditions. some nodes are co nnected to the common power supply, while other nodes are disconnected from the power supply and in power-do wn state. regardless of whether the can bus subscriber is supplied or not, each subscriber connected to the common bus media must not interfere with the communication. the tle7250gvio is designed to support ?p artially-supplied? networks. in the power-down state, the receiver input resistors are switched off and the transceiver input has a high resistance. the voltage level at the digital input txd and the digital ou tput rxd is determined by t he power supply level at the v io pin. depending on the voltage level at the v io pin, the signal levels on the lo gic pins (nen, txd and rxd) are compatible with microcontrollers having 5 v or 3.3 v i/o supply. usually, the v io power supply of the transceiver is connected to same power supply as the i/o power supply of the microcontroller.
data sheet 8 rev. 1.1, 2014-04-23 tle7250gvio functional description 4.2 modes of operation two different modes of operation are available on the tl e7250gvio. each mode has specific characteristics in terms of quiescent current or data transmission. th e digital input pin nen is used for mode selection. figure 4 illustrates the different mo de changes depending on the status of the nen pin. after supplying v cc and v io to the hs can transceiver, the tle7250gvio starts in stand-by mo de. the internal pull-up resistor at the nen pin sets the tle7250gvio to stand-by mode by default. if the microcontroller is up and running, the tle7250gvio can switch to any mode of operation within the time period for mode change t mode . figure 4 modes of operation the tle7250gvio has 2 major modes of operation: ? stand-by mode ? normal-operating mode table 2 modes of operation mode nen bus bias comments normal-operating mode ?low? v cc /2 the transmitter is active. the receiver is active. stand-by ?high? gnd the transmitter is disabled. the receiver is disabled. v cc off ?low? or ?high? floating the transmitter is disabled. the receiver is disabled. undervoltage detection on v cc and v io power-down v cc < v cc(uv) start C up supply v cc and v io v io < v io(uv) nen = 0 normal-operating mode nen = 1 stand-by mode nen = 0 nen = 1
tle7250gvio functional description data sheet 9 rev. 1.1, 2014-04-23 4.3 normal-operating mode in the normal-operating mode, the hs can transceiver tle7250gvio sends the serial data stream on the txd pin to the can bus. the data on the can bus is displa yed at the rxd pin simultan eously. in normal-operating mode, all functions of the tle7250gvio are active: ? the transmitter is active and drives data from the txd to the can bus. ? the receiver is active and provides t he data from the can bus to the rxd pin. ? the bus biasing is set to v cc /2. ? the undervoltage monitoring at the power supply v cc and at the power supply v io is active. to enter the normal-operating mode, set the nen pin to logical ?low? (see table 2 or figure 4 ). the nen pin has an internal pull-up resistor to the power-supply v io . 4.4 stand-by mode the stand-by mode is an idle mode of the tle7250g vio with optimized power cons umption. in the stand-by mode, the tle7250gvio can not send or receive any data. the transmitter and the receiver unit are disabled. both can bus pins, canh and canl are c onnected to gnd via the input resistors. ? the transmitter is disabled. ? the receiver is disabled. ? the input resistors of the receiver are connected to gnd. ? the undervoltage monitoring at the power supply v cc and at the power supply v io is active. to enter the stand-by mode, set the pin nen to logical ?high? (see table 2 or figure 4 ). the nen pin has an internal pull-up resistor to the power-supply v io . if the stand-by mode is not used in the final application, the nen pin needs to be connected to gnd. 4.5 power-down state the power-down state means that the tle7250gvio is not supplied. in power-down state, the differential input resistors of the receiver are switched off. the canh and canl bus interface of the tle7250gvio act as high- impedance input with a very small leakage current. the hi gh-ohmic input does not influence the ?recessive? level of the can network and allows an optimize d eme performance of the entire can network.
data sheet 10 rev. 1.1, 2014-04-23 tle7250gvio fail-safe functions 5 fail-safe functions 5.1 short-circuit protection the canh and canl bus outputs are short-circuit proof, either against gnd or a positive supply voltage. a current limiting circuit protects the transceiver against da mage. if the device heats up due to a continuous short on the canh or canl, the intern al overtemperature protection s witches off the bus transmitter. 5.2 unconnected logic pins all logic input pins have an internal pull-up resistor to v io . in case the v io supply is activated and the logical pins are open or floating, the tle7250gvio enters the stand- by mode by default. in sta nd-by mode, the transmitter of the tle7250gvio is disabled, the bu s bias is connected to gnd and the hs can tle7250g transceiver does not influence the data on the can bus. 5.3 txd time-out function the txd time-out feature protects the can bus against per manent blocking in case the logical signal on the txd pin is continuously ?low?. a continuous ?low? signal on the txd pin can have its root cause in a locked-up microcontroller or in a short on the printed circuit board for example. in the normal-operating mode, a logical ?low? signal on the txd pin for the time t > t txd enables the txd time-out feature and the tle7250gvio disables the transmitter (see figure 5 ). the receiver is still active and the data on the bus continues to be monitored by the rxd output pin. figure 5 txd time-out function figure 5 illustrates how the transmitter is deactivated and activated again. a permanent ?low? si gnal on the txd input pin activates the txd time-out function and deactivate s the transmitter. to release the transmitter after a txd time-out event, the tle7250gvio requires a signal change on the txd input pin from logi cal ?low? to logical ?high?. 5.4 undervoltage detection the hs can transceiver tle7250gvio is provided with undervoltage detection at the power supply v cc and at the power supply v io . in case of undervoltage at v cc or v io , the undervoltage detection changes the operating mode of tle7250gvio to the stand-by mode, regardless of the logical signal on the nen pin (see figure 6 ). if the transceiver tle7250gvio recovers from the undervol tage condition, the operating mode is restored to the programmed mode by the nen pin. txd t t canh canl rxd t txd time-out txd time-out released t > t txd
