TPS3842A010DRLR from Texas Instruments, in a SOT-563. 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 | VDD | power_in | Supply voltage pin, operating range 1.9V to 42V. |
| 2 | SENSE | input | Sense input that monitors the input voltage against the internal threshold, rated 0V to 42V and decoupled from VDD. |
| 3 | RESET | output | Open-drain active-low reset output for the A variant; connect to a pull-up voltage through a pull-up resistor, rated up to 42V. |
| 4 | CTS | input | Capacitor-programmable sense delay (de-glitch) pin that sets the delay when asserting a reset condition, 0V to 5V. |
| 5 | GND | power_in | Ground pin. |
| 6 | CTR | input | Reset time delay pin; connect an external capacitor for adjustable delay or leave floating for the shortest delay, 0V to 5V. |
