UCC27211DDAR 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 of the low-side gate driver (8V to 17V recommended, 20V absolute max), decoupled to VSS with a typical 0.22µF to 4.7µF capacitor. |
| 2 | HB | power_in | High-side bootstrap supply with on-chip bootstrap diode (120V max); needs an external bootstrap capacitor, typically 0.022µF to 0.1µF, with its positive side on this pin. |
| 3 | HO | output | High-side output that connects to the gate of the high-side power MOSFET, referenced to HS (3.7A source, 4.5A sink). |
| 4 | HS | passive | High-side source connection that connects to the source of the high-side power MOSFET and the negative side of the bootstrap capacitor (recommended -1V to 105V). |
| 5 | HI | input | High-side logic input with 2.3V typical rising and 1.6V typical falling threshold, tolerant of -10V to 20V, with 68kΩ internal pull-down to VSS. |
| 6 | LI | input | Low-side logic input with 2.3V typical rising and 1.6V typical falling threshold, tolerant of -10V to 20V, with 68kΩ internal pull-down to VSS. |
| 7 | VSS | power_in | Negative supply terminal of the device, typically ground. |
| 8 | LO | output | Low-side output that connects to the gate of the low-side power MOSFET, referenced to VSS (3.7A source, 4.5A sink). |
| 9 | PowerPAD | power_in | Exposed thermal pad electrically referenced to VSS (GND); connect to a large thermal-mass trace or GND plane to improve thermal performance. |
