TPS22990DMLR from Texas Instruments, in a WSON-10-EP(2x3). 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 | CT | output | Capacitor-to-GND pin used to set the VOUT controlled slew rate (rise time); voltage on this pin can reach 15 V, so a capacitor rated ≥25 V is recommended; without a capacitor, rise time is at its fastest. |
| 2 | NC | unconnected | Not internally connected; no electrical function. |
| 3 | VIN | power_in | Switch input supply; operating range 0.6 V to VBIAS; bypass to GND with a ceramic capacitor (typ. 1 µF) close to the pin. |
| 4 | VBIAS | power_in | Bias voltage input that powers the device; operating range 2.5 V to 5.5 V. |
| 5 | ON | input | Active-high switch control input that enables the load switch when driven high; must not be left floating (tie high or low); VIH,min = 1.05-1.2 V, VIL,max = 0.5 V. |
| 6 | GND | power_in | Device ground reference. |
| 7 | PG | output | Power-good indicator; active-high, open-drain output that requires an external pull-up (e.g., to VOUT or another supply); indicates the pass FET is fully on and output is full-load ready; tie to GND if unused. |
| 8 | VOUT | power_out | Switch output; ganged internally with pins 9 and 10 to carry the full switch current up to 10 A continuous. |
| 9 | VOUT | power_out | Switch output; ganged internally with pins 8 and 10 to carry the full switch current up to 10 A continuous. |
| 10 | VOUT | power_out | Switch output; ganged internally with pins 8 and 9 to carry the full switch current up to 10 A continuous. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
