**Jiangsu RUNIC Tech** · Gate Drivers · SOT-23-5

RS8801HXF5 from Jiangsu RUNIC Tech, in a SOT-23-5. 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 input; the datasheet rates VDD at 4.5V to 18V, and internal UVLO holds OUT low when VDD is below the start threshold (about 4.3V typical). |
| 2 | GND | power_in | Ground pin; all voltages on the device are referenced to GND. |
| 3 | IN+ | input | Non-inverting input for the PWM control signal; in inverting configuration, connect IN+ to VDD to enable the output, and OUT is held low if IN+ is unbiased or floating. |
| 4 | IN- | input | Inverting input for the PWM control signal; in non-inverting configuration, connect IN- to GND to enable the output, and OUT is held low if IN- is unbiased or floating. |
| 5 | OUT | output | Sourcing/sinking current output of the driver, rated for 5A peak source and sink current at VDD = 12V. |
