TPS3840DL28DBVRQ1 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 | tri_state | Open-drain active-low reset output; driven low (asserted) when VDD drops below 2.8V or MR pin is pulled to logic low, remaining asserted for programmable delay time tD after condition recovery. |
| 2 | VDD | power_in | Input supply voltage monitored against threshold of 2.8V with 100mV hysteresis; accepts 1.5V to 10V operating range. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Active-low manual reset input; pulling to logic low asserts reset regardless of VDD, releasing when returned to logic high or floating with internal 100kΩ pull-up resistor. |
| 5 | CT | passive | External capacitor connection point for programming reset delay time; connect 0-10µF capacitor to GND for delay 50µs to 6.2s, or leave open for minimum fixed delay. |
