TPS3838E18DBVR

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

TPS3838E18DBVR 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 CT input Capacitor time delay pin: connect to GND to set the reset delay to 10 ms, or to VDD to set it to 200 ms.
2 GND power_in Ground reference; all voltage ratings in the datasheet are specified with respect to GND.
3 MR input Manual reset input: when driven to logic low, RESET activates; if unused, connect to VDD to minimize current consumption.
4 RESET output Active-low open-drain reset output that goes low when VDD falls below VIT or MR is low, and releases after the reset delay tD once VDD exceeds VIT plus VHYS.
5 VDD power_in Input supply voltage monitored by the device, with a recommended operating range of 1.6 V to 6 V and an absolute maximum of 7 V.
