UCC27321P from Texas Instruments, in a PDIP-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 | Supply voltage and power input (4.5 V to 15 V recommended, 16 V absolute max); must be connected externally to the other VDD pin (pin 8). |
| 2 | IN | input | Driver input signal with logic-compatible threshold and hysteresis (logic 1 threshold 1.6 V min to 2.5 V max, logic 0 threshold 0.8 V min to 1.5 V max). |
| 3 | ENBL | input | Enable input with logic-compatible threshold and hysteresis, internally pulled up to VDD through 100 kΩ for active-high operation and can be left open; output is low regardless of IN when disabled. |
| 4 | AGND | power_in | Analog (control circuit) ground, which must be connected to PGND by a single thick trace directly under the device. |
| 5 | PGND | power_in | Common ground for the output stage, which must be connected very closely to the source of the power MOSFET being driven. |
| 6 | OUT | output | Driver output providing 9-A peak drive current to the power MOSFET gate; must be connected externally to the other OUT pin (pin 7). |
| 7 | OUT | output | Driver output providing 9-A peak drive current to the power MOSFET gate; must be connected externally to the other OUT pin (pin 6). |
| 8 | VDD | power_in | Supply voltage and power input (4.5 V to 15 V recommended, 16 V absolute max); must be connected externally to the other VDD pin (pin 1). |
