Reset timing and output drive
The reset timeout is 10 ms minimum — enough to let the monitored rail stabilise after power-up before releasing the reset. The open-drain output pulls low when VDD drops below the 1.71 V threshold; it requires an external pull-up resistor to the supervisor's supply or the monitored rail. The single-voltage monitor suits a dedicated core-supply watchdog in an ECU or sensor module.
SOT-23-5 footprint
Housed in a SOT-23-5 package (SC-74A, SOT-753), surface-mount only. The five-pin layout is standard for single-voltage supervisors in this family — the pinout matches other TPS3838 variants, so a board laid out for this part can accept a different threshold version with the same base number if the voltage changes in a future design revision.
