# TC4427AVOA713

**Microchip Tech** · Gate Drivers · SOIC-8

TC4427AVOA713 from Microchip Tech, 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 | NC | unconnected | No connection; this pin is not internally connected on the SOIC package. |
| 2 | IN A | input | MOSFET driver input A is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, and any unused driver input must be grounded. |
| 3 | GND | power_in | Ground is the return path for bias and high-peak discharge current and should tie to a ground plane or a very short trace to the bias supply return. |
| 4 | IN B | input | MOSFET driver input B is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, and any unused driver input must be grounded. |
| 5 | OUT B | output | Driver output B is a low-impedance CMOS push-pull output with equal pull-up and pull-down strength, rated for 1.5 A peak output current. |
| 6 | VDD | power_in | Bias supply input rated 4.5 V to 18 V with respect to GND (22 V absolute maximum supply), to be bypassed with local ceramic capacitors sized for the capacitive load. |
| 7 | OUT A | output | Driver output A is a low-impedance CMOS push-pull output with equal pull-up and pull-down strength, rated for 1.5 A peak output current. |
| 8 | NC | unconnected | No connection; this pin is not internally connected on the SOIC package. |
