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. |
