TPS3840DL37DBVRQ1

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

TPS3840DL37DBVRQ1 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 that is driven low when MR is pulled low or VDD falls below VIT-, and stays asserted for the delay time tD after MR is floating or above VMR_L and VDD rises above VIT+; absolute maximum voltage is 12 V and recommended RESET current is 0 to ±5 mA.
2 VDD power_in Input supply voltage that the device monitors, with a recommended range of 1.5 V to 10 V and an absolute maximum of 12 V.
3 GND power_in Ground reference pin for the device.
4 MR / NC input Manual reset input that asserts RESET when pulled to a logic low (VMR_L); it may be left floating when not in use, must not be driven above VDD, and has an absolute maximum of 12 V.
5 CT passive Capacitor time-delay pin where an external capacitor to GND sets the reset delay tD, left floating for the smallest fixed delay, with an absolute maximum of 5.5 V.
