TPS3840PL48DBVR 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 | Low level active output reset signal; asserted to logic low when VDD falls below threshold voltage (VIT-) or MR pin is pulled to logic low, released to logic high after reset delay time when VDD rises above VIT+ and MR returns to high or floating. |
| 2 | VDD | power_in | Input power supply voltage from 1.5V to 10V; monitored by internal comparator with fixed negative threshold (VIT-) of 4.8V and hysteresis (VHYS) of 200mV typical. |
| 3 | GND | power_in | Ground; negative power return and reference voltage for CT timing capacitor. |
| 4 | MR | input | Manual reset input; pull below 0.6V logic low (V_MR_L) to assert reset regardless of VDD, or leave floating or above 0.7×VDD logic high (V_MR_H) for normal voltage monitoring operation. |
| 5 | CT | passive | Capacitor delay time pin; connect external capacitor (up to 10µF) between this pin and ground to program reset delay time from 50µs to 6.2s using internal 500kΩ resistor, or leave floating for 50µs fixed minimum delay. |
