COS4423SR

COSINE · Gate Drive ICs · SOP-8

COS4423SR from COSINE, in a SOP-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 internal connection on this pin.
2 IN A input MOSFET driver input A is a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis, and output A is held LOW if this input is unbiased or floating.
3 GND power_in Device return ground that carries high peak current when the capacitive load is discharged and should have a low-impedance connection to the bias supply return.
4 IN B input MOSFET driver input B is a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis, and output B is held LOW if this input is unbiased or floating.
5 OUT B output Channel B low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, held LOW if the input is unbiased or floating.
6 VDD power_in Bias supply for the MOSFET driver, rated 4.5V to 25V with respect to GND and to be bypassed with local ceramic capacitors (1.0 µF suggested).
7 OUT A output Channel A low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, held LOW if the input is unbiased or floating.
8 NC unconnected No internal connection on this pin.
