Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3840PL28DBVR 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 reset output for the TPS3840PL: driven low when MR is pulled to logic low or VDD falls below the negative threshold VIT-, and held low for the reset delay tD after release before returning high. |
| 2 | VDD | power_in | Input supply voltage, monitored by the device; the recommended operating range is 1.5 V to 10 V, with an absolute maximum of 12 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
| 4 | MR | input | Manual reset input: pulling it below VMR_L (600 mV max) asserts reset, and it can be left floating or pulled to VMR_H (0.7 VDD min) for normal operation, but VMR must never exceed VDD. |
| 5 | CT | passive | Reset delay programming pin: a capacitor from CT to GND sets tD (up to 10 µF is recommended), and leaving CT floating gives the minimum fixed delay of 50 µs. |
