TC4427ACOA713

Microchip Tech · Gate Drivers · SOIC-8

TC4427ACOA713 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.
2 IN A input MOSFET driver input A is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, logic '1' input requires at least 2.4 V and logic '0' input must be at most 0.8 V, and any unused driver input must be grounded.
3 GND power_in Ground is the return path for both the bias current and the high-peak current that discharges the external load capacitance, and should be tied to a ground plane or have a very short trace to the bias supply source return.
4 IN B input MOSFET driver input B is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, logic '1' input requires at least 2.4 V and logic '0' input must be at most 0.8 V, and any unused driver input must be grounded.
5 OUT B output MOSFET driver output B is a low-impedance CMOS push-pull output with equal pull-up and pull-down strength, giving matched rise and fall times, and a peak output current of 1.5 A at VDD = 18 V.
6 VDD power_in Bias supply input for the MOSFET driver, rated 4.5 V to 18 V with respect to GND, which should be bypassed with local ceramic capacitors sized for the capacitive load being driven.
7 OUT A output MOSFET driver output A is a low-impedance CMOS push-pull output with equal pull-up and pull-down strength, giving matched rise and fall times, and a peak output current of 1.5 A at VDD = 18 V.
8 NC unconnected No connection.
