COS4428DR

COSINE · Gate Drivers · DIP-8

COS4428DR from COSINE, in a DIP-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; the datasheet lists this pin as not connected.
2 IN A input MOSFET driver input A is high-impedance and TTL/CMOS compatible, with 300 mV of hysteresis between thresholds, and it withstands negative inputs up to 5V.
3 GND power_in Ground is the device return pin and should have a low-impedance connection to the bias supply return, since high peak current flows out of it when the capacitive load discharges.
4 IN B input MOSFET driver input B is high-impedance and TTL/CMOS compatible, with 300 mV of hysteresis between thresholds; unused inputs can be floated.
5 OUT B output Channel B is a low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, giving matched rise and fall times.
6 VDD power_in Bias supply for the driver, rated 4.5V to 25V with respect to GND, and should be bypassed with local ceramic capacitors (1.0 µF suggested).
7 OUT A output Channel A is a low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, giving matched rise and fall times.
8 NC unconnected No connection; the datasheet lists this pin as not connected.
