# UCC27200DDAR

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

UCC27200DDAR from Texas Instruments, in a SOIC-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 0.22µF to 1µF capacitor; recommended supply is 8 V to 17 V with an absolute maximum of 20 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 that connects to the gate of the high-side power MOSFET. |
| 4 | HS | input | High-side source connection that connects to the source of the high-side power MOSFET and to the negative side of the bootstrap capacitor; the datasheet rates HS at -1 V DC (-5 V for pulses under 100 ns) up to 120 V. |
| 5 | HI | input | High-side logic input that controls the high-side driver. |
| 6 | LI | input | Low-side logic input that controls the low-side driver. |
| 7 | VSS | power_in | Negative supply terminal for the device, generally grounded and used as the reference for all voltages. |
| 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). |
