TPS3840DL46DBVRQ1 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 output driven low when MR pin is pulled to logic low or VDD falls below negative voltage threshold VIT-, remaining asserted for programmed delay time tD. |
| 2 | VDD | power_in | Supply voltage input monitored by TPS3840-Q1 with operating range 1.5V to 10V. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Manual reset input pin; pull to logic low (VMR_L) to assert reset output, can be left floating when not in use. |
| 5 | CT | passive | Capacitor time delay pin for programmable reset delay; connect external capacitor to adjust delay from 50µs (no capacitor) to 6.2s (10µF). |
