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

TC4420EOA713 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 | VDD | power_in | Bias supply for the MOSFET driver, rated 4.5V to 18V with respect to the ground pins, and should be bypassed to ground with a local ceramic capacitor (minimum 1.0 µF suggested). |
| 2 | INPUT | input | High-impedance TTL/CMOS compatible control input that can be driven as high as VDD + 0.3V or as low as -5V, and slow rising or falling input edges should be avoided to prevent double-pulsing of the output. |
| 3 | NC | unconnected | No connection. |
| 4 | GND | power_in | Ground return path for the bias current and the high peak discharge currents, which should be tied to a ground plane or connected with very short traces to the bias supply source return. |
| 5 | GND | power_in | Duplicate ground return pin for the bias and high peak discharge currents; it must be connected together with pin 4 for proper operation. |
| 6 | OUTPUT | output | CMOS push-pull output capable of driving a capacitive load with 6.0A peak current and withstanding 1.5A peak reverse current of either polarity; it must be connected together with pin 7 for proper operation. |
| 7 | OUTPUT | output | Duplicate CMOS push-pull output capable of 6.0A peak current and withstanding 1.5A peak reverse current of either polarity; it must be connected together with pin 6 for proper operation. |
| 8 | VDD | power_in | Duplicate bias supply input rated 4.5V to 18V with respect to the ground pins; it must be connected together with pin 1 for proper operation. |
