# UCC27525D

**Texas Instruments** · Gate Drivers · SOIC-8

UCC27525D from Texas Instruments, in a SOIC-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 | ENA | input | Channel A enable input; drives output low when ENA is biased low regardless of INA state, enables output when biased high or floating; TTL/CMOS compatible with thresholds 0.8-1.2V (low) to 1.8-2.3V (high). |
| 2 | INA | input | Channel A non-inverting input; output remains low when input is unbiased or floating; TTL/CMOS compatible with thresholds 0.8-1.2V (low) to 1.8-2.3V (high) and 1V hysteresis. |
| 3 | GND | power_in | Ground reference; all signal voltages referenced to this pin. |
| 4 | INB | input | Channel B non-inverting input; output remains low when input is unbiased or floating; TTL/CMOS compatible with thresholds 0.8-1.2V (low) to 1.8-2.3V (high) and 1V hysteresis. |
| 5 | OUTB | output | Channel B output; drives gate with 5A peak source/sink current capability, rail-to-rail voltage swing from GND to VDD, 10-14ns typical fall time. |
| 6 | VDD | power_in | Auxiliary power supply input; rated 4.5V to 18V with internal UVLO protection that holds outputs low below 3.8V typical rising threshold. |
| 7 | OUTA | output | Channel A output; drives gate with 5A peak source/sink current capability, rail-to-rail voltage swing from GND to VDD, 6-10ns typical rise time. |
| 8 | ENB | input | Channel B enable input; drives output low when ENB is biased low regardless of INB state, enables output when biased high or floating; TTL/CMOS compatible with thresholds 0.8-1.2V (low) to 1.8-2.3V (high). |
