UCC21732QDWRQ1 from Texas Instruments, in a SOIC-16-300mil. 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 | AIN | input | Isolated analog sensing input for temperature or voltage measurement; parallel small capacitor to COM for noise immunity or tie to COM if unused. |
| 2 | OC | input | Over-current detection input supporting SenseFET, DESAT, and shunt resistor sensing methods; tie to COM if unused. |
| 3 | COM | power_in | Common ground reference connected to IGBT emitter pin or SiC-MOSFET source pin for output side isolation. |
| 4 | OUTH | output | Gate driver output pull-up providing ±10A peak source current with maximum 33V output drive voltage. |
| 5 | VDD | power_in | Positive supply rail for gate drive voltage (13-33V); bypass with >10-μF capacitor to COM placed close to pin. |
| 6 | OUTL | output | Gate driver output pull-down providing ±10A peak sink current with maximum 33V output drive voltage. |
| 7 | CLMPE | output | External active Miller clamp output for driving external clamp MOSFET gate; leave floating if unused. |
| 8 | VEE | power_in | Negative supply rail for gate drive voltage (return rail); bypass with >10-μF capacitor to COM placed close to pin. |
| 9 | GND | power_in | Input power supply and logic ground reference for control side. |
| 10 | IN+ | input | Non-inverting gate driver control input with <40ns deglitch filter; tie to VCC if unused. |
| 11 | IN- | input | Inverting gate driver control input with <40ns deglitch filter; tie to GND if unused. |
| 12 | RDY | output | Power-good output (open drain) for VCC-GND and VDD-COM supply monitoring; can be paralleled with other RDY signals. |
| 13 | FLT | output | Active-low fault alarm output (open drain) upon overcurrent or short-circuit detection; can be paralleled with other fault signals. |
| 14 | RST/EN | input | Reset and enable/disable input; requires >1000ns low pulse width to reset over-current fault condition signaled on FLT pin. |
| 15 | VCC | power_in | Input power supply (3-5.5V) for control side; bypass with >1-μF capacitor to GND placed close to pin. |
| 16 | APWM | output | Isolated analog-to-PWM sensor output for temperature or voltage measurement across isolation barrier; leave floating if unused. |
