UCC27211DR 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 voltage for the lower-gate driver, operating range 8V to 17V with 0.22µF to 4.7µF decoupling capacitor recommended. |
| 2 | HB | power_in | High-side bootstrap supply; connect positive terminal of bootstrap capacitor to this pin with typical 0.022µF to 0.1µF bypass capacitor. |
| 3 | HO | output | High-side gate driver output; connect to gate of high-side power MOSFET with 3.7A peak source and 4.5A peak sink output current. |
| 4 | HS | passive | High-side source connection; connect to source of high-side power MOSFET and negative terminal of bootstrap capacitor, voltage range −1V to 115V DC. |
| 5 | HI | input | High-side gate driver input, TTL compatible with input voltage range −10V to 20V independent of VDD supply voltage. |
| 6 | LI | input | Low-side gate driver input, TTL compatible with input voltage range −10V to 20V independent of VDD supply voltage. |
| 7 | VSS | power_in | Negative supply terminal (ground reference) for the device. |
| 8 | LO | output | Low-side gate driver output; connect to gate of low-side power MOSFET with 3.7A peak source and 4.5A peak sink output current. |
