Texas Instruments · Gate Drivers · SO-8
UCC27201ADDAR from Texas Instruments, in a SO-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 gate driver supply (8-17V operating range, 20V absolute max) with 0.22-1.0μF de-coupling capacitor to VSS required. |
| 2 | HB | power_in | High-side bootstrap supply with on-chip bootstrap diode (anode to VDD, cathode to HB); connect 0.022-0.1μF external capacitor between HB and HS. |
| 3 | HO | output | High-side gate driver output (referenced to HS) with 3A peak source and sink current; connects to high-side MOSFET gate. |
| 4 | HS | input | High-side reference node (-18V to 120V rating) connected to high-side MOSFET source and bootstrap capacitor negative terminal; voltage on HS input to level-shift circuit. |
| 5 | HI | input | High-side control input (UCC27201A: 1.9-2.7V rising threshold, 1.6-1.9V falling threshold) with 68kΩ pull-down to VSS. |
| 6 | LI | input | Low-side control input (UCC27201A: 1.3-1.9V threshold range) with 68kΩ pull-down to VSS. |
| 7 | VSS | power_in | Negative supply (ground) reference; internally connected to exposed thermal pad on DRC package only. |
| 8 | LO | output | Low-side gate driver output (referenced to VSS) with 3A peak source and sink current; connects to low-side MOSFET gate. |
