general description the max6511/max6512/max6513 are fully integrated, remote temperature switches that use an external p-n junction (typically a diode-connected transistor) as the sensing element to measure the remote temperature. these devices assert a logic signal when the tempera- ture crosses a factory-programmed threshold. available trip thresholds are from +45? to +125? in 10? incre- ments. accuracy is within ?? (t a = -5? to +55?) or ?? (t a = -40? to +85?). hysteresis is pin selec- table to 5? or 10?. the max6511 has an active-low cmos output and the max6513 has an active-high cmos output. the max6512 has an open-drain output. the output is asserted when the temperature exceeds the threshold value. the active-low open-drain output is intended to interface with a microprocessor (?) reset or interrupt input. the active-high cmos output can directly drive a power fet to control a cooling fan. the max6511/max6512/max6513 operate from a +3.0v to +5.5v supply and typically consume 400? of supply current. they are available in the small 6-pin sot23. the max6613 is also available in a 6-pin lead- free tdfn package. ________________________applications cpu temperature monitoring in high-speed computers multichip modules battery packs temperature control temperature alarms fan control features continuously measure external junction temperature factory-programmed temperature threshold from +45? to +125? in 10? increments insensitive to series parasitic resistance active-low cmos output (max6511) or open-drain output for overtemperature alarm (max6512) or active-high output (max6513) for direct fan control <100ms response time accuracy ??

detailed description the max6511/max6512/max6513 fully integrated tem- perature switches incorporate a precision bandgap ref- erence, a conversion block, a current source, and a comparator (figure 1). these devices use an external p-n junction as the temperature-sensing element. they steer bias currents through the external diode, measure the forward voltages, and compute the temperature using a precision chopper stabilized amplifier. resistance values of less than 100 ? in series with the external sense junction will result in trip-point errors <1 c. the max6511/max6512/max6513 provide noise immunity by integration and oversampling of the diode voltage, but good design practice includes routing the dxp and dxn lines away from noise sources, such as high-speed digital lines, switching regulators, induc- tors, and transformers. the dxp and dxn traces should be paired together and surrounded by ground plane whenever possible. in applications where the temperature changes rapidly, the measured temperature will be approximately equal to the average value of the temperature during the measurement period. the max6512 has an active-low, open-drain output struc- ture that can only sink current. the max6511 has an active- low cmos output structure, and the max6513 has an active-high cmos output. the max6511/max6512/max6513 are available with preset temperature thresholds from +45 c to +125 c in 10 c increments. max6511/max6512/max6513 low-cost, remote sot temperature switches 4 _______________________________________________________________________________________ pin description pin max6511 max6512 max6513 name function 11v dd power-supply input, +3.0v to +5.5v . bypass v dd to gnd with a 0.1f capacitor. 2 2 gnd ground 3 3 hyst hysteresis selection. hysteresis is 10 c for hyst = v dd , 5 c for hyst = gnd. 4 tover cmos active-low output (max6511) or open-drain active-low output (max6512). tover goes low when the temperature exceeds the factory- programmed temperature threshold. this pin can only sink current in the max6512. 4 tover cmos active-high output (max6513). tover goes high when the temperature exceeds the factory-programmed temperature threshold. 55dxn this pin connects to the negative (cathode) terminal of the external p-n sense junction. dxn must be connected to gnd. 6 6 dxp this pin connects to the positive (anode) terminal of the external p-n sense junction. dxp dxn temperature conversion bandgap voltage reference compar- ator latch tover figure 1. functional block diagram
hysteresis input the hyst pin is a cmos-compatible input that selects hysteresis at either a high level (10 c for hyst = v dd ) or a low level (5 c for hyst = gnd). hysteresis pre- vents the output from chattering when the temperature is near the trip point. the hyst pin must not float. the output asserts when the temperature exceeds the trip point and deasserts when the temperature falls back below the trip point minus the hysteresis. for example, if the trip point is 105 c, the output will assert at 105 c and will not deassert until temperature falls below 105 c minus the hysteresis (e.g., 95 c if 10 c hysteresis is chosen) (figure 2). applications information remote-diode selection to ensure best accuracy, use a good-quality diode- connected transistor. suggested devices are listed in table 1. large power transistors are not recommend- ed. tight specifications for forward current gain indi- cate the manufacturer has good process controls and that the devices have consistent v be characteristics. the max6511/max6512/max6513 can also measure the die temperature of cpus and other integrated cir- cuits having on-board temperature-sensing diodes. use the monitor s output to reset the p, assert an inter- rupt, activate a cooling fan, or trigger an external alarm. noise filtering capacitors a quality ceramic capacitor must be connected across the dxp/dxn inputs to maintain temperature threshold accuracy by filtering out noise. the capacitor should be located physically close to the dxp/dxn pins and should typically have a value of 2200pf. larger capaci- tor values can cause temperature measurement errors. a 50% variation from the recommended capacitor value can cause up to 1 c error. max6511/max6512/max6513 low-cost, remote sot temperature switches _______________________________________________________________________________________ 5 figure 2. temperature trip threshold hysteresis trip temperature trip temperature hysteresis tover (max6511) time manufacturer model number central semiconductor (usa) cmpt3904 on (usa) mmbt3904 rohm semiconductor (japan) sst3904 samsung (korea) kst3904-tf siemens (germany) smbt3904 zetex (england) fmmt3904ct-nd table 1. sensor transistor manufacturers note: transistors must be diode connected (base shorted to collector).
