TPS3840PL48DBVR

Texas Instruments · Supervisor And Reset ICs · SOT-23-5

TPS3840PL48DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RESET output Low level active output reset signal; asserted to logic low when VDD falls below threshold voltage (VIT-) or MR pin is pulled to logic low, released to logic high after reset delay time when VDD rises above VIT+ and MR returns to high or floating.
2 VDD power_in Input power supply voltage from 1.5V to 10V; monitored by internal comparator with fixed negative threshold (VIT-) of 4.8V and hysteresis (VHYS) of 200mV typical.
3 GND power_in Ground; negative power return and reference voltage for CT timing capacitor.
4 MR input Manual reset input; pull below 0.6V logic low (V_MR_L) to assert reset regardless of VDD, or leave floating or above 0.7×VDD logic high (V_MR_H) for normal voltage monitoring operation.
5 CT passive Capacitor delay time pin; connect external capacitor (up to 10µF) between this pin and ground to program reset delay time from 50µs to 6.2s using internal 500kΩ resistor, or leave floating for 50µs fixed minimum delay.
