UCC27282D 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 with a typical 1 µF capacitor; recommended supply range is 5.5 V to 16 V and the absolute maximum is 20 V. |
| 2 | HB | power_in | High-side bootstrap supply; the bootstrap diode is on-chip but an external bootstrap capacitor (typically 0.1 µF) is required, and VHB-HS must stay below 16 V recommended (20 V absolute maximum). |
| 3 | HO | output | High-side output that drives the gate of the high-side MOSFET or one end of an external gate resistor, with DC voltage limited to VHS - 0.3 V to VHB + 0.3 V. |
| 4 | HS | power_in | High-side source connection, tied to the high-side MOSFET source and the negative side of the bootstrap capacitor; voltage is rated -8 V to 100 V recommended (-10 V DC and -14 V for pulses under 100 ns absolute maximum). |
| 5 | HI | input | High-side logic input; input voltages are rated -5 V to 20 V absolute maximum, with 0 V to VDD + 0.3 V recommended. |
| 6 | LI | input | Low-side logic input; input voltages are rated -5 V to 20 V absolute maximum, with 0 V to VDD + 0.3 V recommended. |
| 7 | VSS | power_in | Negative supply terminal for the device, generally the system ground, to which all voltages are referenced. |
| 8 | LO | output | Low-side output that drives the gate of the low-side MOSFET or one end of an external gate resistor, with DC voltage limited to -0.3 V to VDD + 0.3 V (-2 V for pulses under 100 ns). |
