TPS3840DL18DBVRQ1 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 | Active-low open-drain reset output; driven low when MR is pulled to logic low or VDD falls below negative voltage threshold VIT- (1.8V); remains asserted for delay time (tD, 50µs to 6.2s via CT capacitor) after MR release and VDD rise above VIT- plus 100mV hysteresis. |
| 2 | VDD | power_in | Input supply voltage monitored by device over operating range 1.5V to 10V; quiescent current 700nA maximum. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Manual reset input (active-low); pulling to logic low asserts reset output; release to float de-asserts reset after programmable delay; voltage range 0V to VDD. |
| 5 | CT | passive | Capacitor connection pin for programming reset delay; connect external capacitor to adjust delay from 50µs to 6.2s, or leave floating for 350µs fixed delay. |
