UCC27201ADPRR from Texas Instruments, in a WSON-10-EP(4x4). 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 | Positive supply to the lower gate driver; decouple to VSS with a typical 0.22μF to 1.0μF capacitor, and the absolute maximum VDD is 20 V (recommended 8 V to 17 V). |
| 2 | HB | power_in | High-side bootstrap supply; the bootstrap diode is on-chip but an external bootstrap capacitor is required, typically 0.022μF to 0.1μF depending on the high-side MOSFET gate charge. |
| 3 | HO | output | High-side output; connect to the gate of the high-side power MOSFET. |
| 4 | HS | power_in | High-side source connection; connect to the high-side MOSFET source and the negative side of the bootstrap capacitor, and the pin withstands -18 V for pulses under 100 ns and 120 V DC. |
| 5 | NC | unconnected | No connection. |
| 6 | NC | unconnected | No connection. |
| 7 | HI | input | High-side input; on the UCC27201A this input has TTL-compatible thresholds. |
| 8 | LI | input | Low-side input; on the UCC27201A this input has TTL-compatible thresholds. |
| 9 | VSS | power_in | Negative supply terminal for the device, generally grounded; all voltages are referenced to VSS. |
| 10 | LO | output | Low-side output; connect to the gate of the low-side power MOSFET. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
