ST890BDR from STMicroelectronics, in a SO-8. 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 | power_in | Input P-channel MOSFET source; bypass IN with a 1 μF capacitor to ground. |
| 2 | IN | power_in | Input P-channel MOSFET source; bypass IN with a 1 μF capacitor to ground. |
| 3 | ON | input | Active-low switch ON input; a logic low turns the switch ON. |
| 4 | GND | power_in | Ground reference. |
| 5 | SET | input | Set current limit input; a resistor from SET to GND sets the current limit for the switch. |
| 6 | OUT | power_out | Switch output P-channel MOSFET drain; bypass OUT with a 0.1 μF capacitor to ground. |
| 7 | OUT | power_out | Switch output P-channel MOSFET drain; bypass OUT with a 0.1 μF capacitor to ground. |
| 8 | FAULT | tri_state | Fault indicator output; this open drain output goes low when in current limit or when the die temperature exceeds 135 °C. |
