COS4422SR

COSINE · Gate Drivers · SOP-8

COS4422SR 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 VDD power_in Bias supply for the driver, rated 4.5V to 25V with respect to GND; bypass with local ceramic capacitors sized to the capacitive load (1.0 µF suggested). Pins 1 and 8 are duplicates and both must be connected.
2 INPUT input High-impedance TTL/CMOS compatible control input with 300 mV hysteresis; the output is held LOW if the input is unbiased or floating.
3 NC unconnected No connection.
4 GND power_in Device return ground that should have a low-impedance connection to the bias supply return, since high peak current flows out of the ground pin(s) when the load is discharged. Pins 4 and 5 are duplicates and both must be connected.
5 GND power_in Device return ground that should have a low-impedance connection to the bias supply return, since high peak current flows out of the ground pin(s) when the load is discharged. Pins 4 and 5 are duplicates and both must be connected.
6 OUTPUT output Low-impedance CMOS push-pull gate drive output with matched pull-up and pull-down strength; held LOW if the input is unbiased or floating. Pins 6 and 7 are duplicates and both must be connected.
7 OUTPUT output Low-impedance CMOS push-pull gate drive output with matched pull-up and pull-down strength; held LOW if the input is unbiased or floating. Pins 6 and 7 are duplicates and both must be connected.
8 VDD power_in Bias supply for the driver, rated 4.5V to 25V with respect to GND; bypass with local ceramic capacitors sized to the capacitive load (1.0 µF suggested). Pins 1 and 8 are duplicates and both must be connected.
