drv8803 www.ti.com slvsaw5b ? july 2011 ? revised february 2012 functional description output drivers the drv8803 contains four protected low-side drivers. each output has an integrated clamp diode connected to a common pin, vclamp. vclamp can be connected to the main power supply voltage, vm. it can also be connected to a zener or tvs diode to vm, allowing the switch voltage to exceed the main supply voltage vm. this connection can be beneficial when driving loads that require very fast current decay, such as unipolar stepper motors. in all cases, the voltage on the outputs must not be allowed to exceed the maximum output voltage specification. parallel interface operation the drv8803 is controlled with a simple parallel interface. logically, the interface is shown in figure 2 . figure 2. parallel interface operation nenbl and reset operation the nenbl pin enables or disables the output drivers. nenbl must be low to enable the outputs. note that nenbl has an internal pulldown. the reset pin, when driven active high, resets internal logic. all inputs are ignored while reset is active. note that reset has an internal pulldown. an internal power-up reset is also provided, so it is not required to drive reset at power-up. copyright ? 2011 ? 2012, texas instruments incorporated submit documentation feedback 7 product folder link(s): drv8803 in1 in4 in3 in2 nenbl out1 out2 out3 out4
drv8803 slvsaw5b ? july 2011 ? revised february 2012 www.ti.com protection circuits the drv8803 is fully protected against undervoltage, overcurrent and overtemperature events. overcurrent protection (ocp) an analog current limit circuit on each fet limits the current through the fet by removing the gate drive. if this analog current limit persists for longer than the t ocp deglitch time (approximately 3.5 s), the driver will be disabled and the nfault pin will be driven low. the driver will remain disabled for the t retry retry time (approximately 1.2 ms), then the fault will be automatically cleared. the fault will be cleared immediately if either reset pin is activated or vm is removed and re-applied. thermal shutdown (tsd) if the die temperature exceeds safe limits, all output fets will be disabled and the nfault pin will be driven low. once the die temperature has fallen to a safe level, operation will automatically resume. undervoltage lockout (uvlo) if at any time the voltage on the vm pin falls below the undervoltage lockout threshold voltage, all circuitry in the device will be disabled, and internal logic will be reset. operation will resume when vm rises above the uvlo threshold. 8 submit documentation feedback copyright ? 2011 ? 2012, texas instruments incorporated product folder link(s): drv8803
drv8803 www.ti.com slvsaw5b ? july 2011 ? revised february 2012 thermal information thermal protection the drv8803 has thermal shutdown (tsd) as described above. if the die temperature exceeds approximately 150 c, the device will be disabled until the temperature drops to a safe level. any tendency of the device to enter tsd is an indication of either excessive power dissipation, insufficient heatsinking, or too high an ambient temperature. power dissipation power dissipation in the drv8803 is dominated by the power dissipated in the output fet resistance, or rds(on). average power dissipation of each fet when running a static load can be roughly estimated by equation 1 : (1) where p is the power dissipation of one fet, r ds(on) is the resistance of each fet, and i out is equal to the average current drawn by the load. note that at start-up and fault conditions this current is much higher than normal running current; these peak currents and their duration also need to be taken into consideration. when driving more than one load simultaneously, the power in all active output stages must be summed. the maximum amount of power that can be dissipated in the device is dependent on ambient temperature and heatsinking. note that r ds(on) increases with temperature, so as the device heats, the power dissipation increases. this must be taken into consideration when sizing the heatsink. heatsinking the drv8803dw package uses a standard soic outline, but has the center pins internally fused to the die pad in order to more efficiently remove heat from the device. the two center leads on each side of the package should be connected together to as large a copper area on the pcb as is possible to remove heat from the device. if the copper area is on the opposite side of the pcb from the device, thermal vias are used to transfer the heat between top and bottom layers. in general, the more copper area that can be provided, the more power can be dissipated. the DRV8803PWP package uses an htssop package with an exposed powerpad ? . the powerpad package uses an exposed pad to remove heat from the device. for proper operation, this pad must be thermally connected to copper on the pcb to dissipate heat. on a multi-layer pcb with a ground plane, this can be accomplished by adding a number of vias to connect the thermal pad to the ground plane. on pcbs without internal planes, copper area can be added on either side of the pcb to dissipate heat. if the copper area is on the opposite side of the pcb from the device, thermal vias are used to transfer the heat between top and bottom layers. for details about how to design the pcb, refer to ti application report slma002 , "powerpad thermally enhanced package" and ti application brief slma004 , "powerpad made easy", available at www.ti.com . copyright ? 2011 ? 2012, texas instruments incorporated submit documentation feedback 9 product folder link(s): drv8803 p = r ds(on) (i ) out 2
