**Texas Instruments** · Gate Drivers · SOIC-8

UCC27282QDDAQ1 from Texas Instruments, in a SOIC-8. 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 low-side gate driver, decoupled to VSS (typical 1 µF); recommended supply range is 5.5 V to 16 V with an absolute maximum of 20 V. |
| 2 | HB | power_in | High-side bootstrap supply with on-chip bootstrap diode and an external bootstrap capacitor (typical 0.1 µF); the voltage on HB with respect to HS must stay below 16 V. |
| 3 | HO | output | High-side output that drives the gate of the high-side MOSFET or one end of an external gate resistor; DC output voltage is limited to VHS - 0.3 V to VHB + 0.3 V. |
| 4 | HS | power_in | High-side source connection to the high-side MOSFET source and the negative side of the bootstrap capacitor; recommended voltage range is -8 V to 100 V (-12 V for pulses under 100 ns). |
| 5 | HI | input | High-side logic input; recommended input voltage range is 0 V to VDD + 0.3 V. |
| 6 | LI | input | Low-side logic input; recommended input voltage range is 0 V to VDD + 0.3 V. |
| 7 | VSS | power_in | Negative supply terminal for the device, generally the system ground; all voltage limits in the datasheet are referenced to VSS. |
| 8 | LO | output | Low-side output that drives the gate of the low-side MOSFET or one end of an external gate resistor; DC output voltage is limited to -0.3 V to VDD + 0.3 V. |
