TPS22975DSGR from Texas Instruments, in a WSON-8-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 | VIN | power_in | Switch input (source of the pass MOSFET). Recommended input voltage range 0.6 V to VBIAS. Pins 1 and 2 must be tied together externally; a bypass capacitor is recommended to minimize VIN dip. |
| 2 | VIN | power_in | Switch input (source of the pass MOSFET). Must be connected to pin 1. Both VIN pins carry the switched load current (up to 6 A continuous). |
| 3 | ON | input | Active-high switch enable input. Compatible with 1.2, 1.8, 2.5, and 3.3 V logic (VIH ≥ 1.05 V, VIL ≤ 0.5 V depending on VBIAS/TA). Must not be left floating. |
| 4 | VBIAS | power_in | Bias supply for the device (gate-drive and internal control). Recommended range 2.5 V to 5.7 V; VBIAS must be ≥ VIN. Quiescent current is typically 37 µA at VBIAS = 5 V. |
| 5 | GND | power_in | Device ground. Tie the exposed thermal pad to this net. |
| 6 | CT | passive | Slew-rate / rise-time control pin. A capacitor to GND sets the VOUT rise time to minimize inrush current; may be left floating for the default slew rate. |
| 7 | VOUT | power_out | Switch output (drain of the pass MOSFET). Pins 7 and 8 must be tied together externally to carry up to 6 A continuous. On the TPS22975 variant an internal ~230 Ω pulldown pulls VOUT to GND when the switch is off (quick-output discharge). |
| 8 | VOUT | power_out | Switch output (drain of the pass MOSFET). Must be connected to pin 7. |
| 9 | PAD | passive | Exposed thermal pad on the package bottom. Tie to GND and connect to a copper pour for thermal dissipation. |
