UCC27712QDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LI | input | Logic input for low-side driver; when unbiased or floating, LO is held low; input voltage range -4 V to 20 V. |
| 2 | HI | input | Logic input for high-side driver; when unbiased or floating, HO is held low; input voltage range -4 V to 20 V. |
| 3 | VDD | power_in | Bias supply input for input logic and low-side driver output; bypass to COM with 0.1 µF or larger ceramic capacitor; recommended 10 V to 20 V (IGBT) or 10 V to 17 V (MOSFET). |
| 4 | COM | power_in | Ground reference. |
| 5 | LO | output | Low-side driver output. |
| 6 | HS | power_in | Return for high-side floating supply; operating range -11 V to 600 V. |
| 7 | HO | output | High-side driver output. |
| 8 | HB | power_in | High-side floating supply; bypass to HS with capacitor typically 10 times the MOSFETs/IGBTs gate capacitance; recommended 10 V to 20 V (IGBT) or 10 V to 17 V (MOSFET) above HS. |
