TPS3840PL42DBVR

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

TPS3840PL42DBVR 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 driven low when MR pin is pulled below 600mV or VDD falls below 4.2V threshold (VIT-), returning high after reset delay time (tD) when conditions clear.
2 VDD power_in Input supply voltage monitored for undervoltage at 4.2V threshold; operating range 1.5V to 10V with quiescent current 300nA typical, 700nA maximum.
3 GND power_in Ground reference.
4 MR input Manual reset input, active-low; pulling below 600mV triggers reset regardless of VDD with internal pullup resistance 100kΩ to VDD.
5 CT passive Capacitor connection for programmable reset delay time from 50µs (open circuit) to 6.2s (10µF) using internal 350-650kΩ resistance.
