TPS3840DL31DBVR

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

TPS3840DL31DBVR 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 Active-low open-drain reset output (TPS3840DL): it is driven low when VDD falls below VIT- or MR is pulled low, needs an external pull-up resistor, may be pulled up to 10 V independent of VDD, and is limited to ±5 mA.
2 VDD power_in Input supply voltage that is also the monitored voltage; the recommended range is 1.5 V to 10 V and the absolute maximum is 12 V.
3 GND power_in Ground reference pin.
4 MR input Active-low manual reset input: pulling it below VMR_L (600 mV max) asserts RESET, leaving it floating or above VMR_H (0.7·VDD min) releases reset after tD, it has an internal 100 kΩ pull-up, and it must not exceed VDD.
5 CT passive Reset-delay timing pin: a capacitor from CT to GND sets tD (no more than 10 µF is recommended), and leaving it floating gives the minimum fixed delay of about 50 µs.
