# UCC27200ADDAR

**Texas Instruments** · Gate Drivers · SOP-8-EP

UCC27200ADDAR from Texas Instruments, in a SOP-8-EP. 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, decoupled to VSS (GND) with a typical capacitor of 0.22 µF to 1.0 µF. |
| 2 | HB | power_in | High-side bootstrap supply; the bootstrap diode is on-chip, an external bootstrap capacitor is required between HB and HS, typically 0.022 µF to 0.1 µF depending on the gate charge of the high-side MOSFET. |
| 3 | HO | output | High-side output that connects to the gate of the high-side power MOSFET. |
| 4 | HS | power_in | High-side source connection that connects to the source of the high-side power MOSFET and the negative side of the bootstrap capacitor; the device can withstand -18 V on HS (repetitive pulse under 100 ns, per the Features list). |
| 5 | HI | input | High-side input that controls the high-side gate driver output HO. |
| 6 | LI | input | Low-side input that controls the low-side gate driver output LO. |
| 7 | VSS | power_in | Negative supply terminal for the device, generally grounded; it is the reference for all voltages on the device. |
| 8 | LO | output | Low-side output that connects to the gate of the low-side power MOSFET. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
