TPS22953DSQR from Texas Instruments, in a WSON-10-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Switch input; bypass to GND with ceramic capacitor. |
| 2 | IN | input | Switch input; bypass to GND with ceramic capacitor. |
| 3 | BIAS | power_in | Bias and power supply pin for the device operating range 2.5V to 5.7V. |
| 4 | EN | input | Active-high switch enable/disable and input UVLO pin; configure with external resistor divider and do not leave floating. |
| 5 | GND | power_in | Device ground. |
| 6 | CT | output | Slew rate control pin; add ceramic capacitor from CT to GND to control VOUT rise time and limit inrush current (25V minimum rated capacitor). |
| 7 | PG | tri_state | Open-drain power good output that pulls low when EN or SNS voltage falls below their respective VIL threshold. |
| 8 | SNS | input | Sense pin for voltage monitoring; configure with external resistor divider and do not leave floating. |
| 9 | OUT | output | Switch output. |
| 10 | OUT | output | Switch output. |
| 11 | PAD | power_in | Exposed thermal pad; tie to GND for thermal and mechanical performance. |
