TPS3840PL30DBVR

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

TPS3840PL30DBVR 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 push-pull reset output that is driven low when VDD falls below VIT- or MR is pulled low, and stays low for the reset delay tD after release before returning high.
2 VDD power_in Input supply voltage that is monitored against the threshold VIT-; the recommended operating range is 1.5 V to 10 V and the absolute maximum is 12 V.
3 GND power_in Ground reference pin.
4 MR/NC input Active-low manual reset input that asserts RESET when pulled below VMR_L (600 mV max); it may be left floating (internal 100 kΩ pull-up to VDD) and must never be driven above VDD.
5 CT passive Reset delay programming pin where a capacitor from CT to GND sets tD (10 µF maximum recommended), and leaving it floating gives the minimum fixed delay of 50 µs.
