COSINE · Gate Drivers · SOP-8
COS4420SR 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 MOSFET driver, rated 4.5V to 25V with respect to the Ground pin, and should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 2 | INPUT | input | High-impedance, TTL/CMOS compatible control input with 300 mV hysteresis; it can be driven from 1.6V to 25V and the output is held LOW if the input is unbiased or floating. |
| 3 | NC | unconnected | No connection. |
| 4 | GND | power_in | Device return pin that should have a low-impedance connection to the bias supply source return, and carries high peak current when the capacitive load is discharged. |
| 5 | GND | power_in | Device return pin that should have a low-impedance connection to the bias supply source return, and carries high peak current when the capacitive load is discharged; duplicate ground pins must both be connected for proper operation. |
| 6 | OUTPUT | output | CMOS push-pull driver output with pull-up and pull-down devices of equal strength, held LOW if the input is unbiased or floating; peak output current 6.0 A. |
| 7 | OUTPUT | output | CMOS push-pull driver output with pull-up and pull-down devices of equal strength, held LOW if the input is unbiased or floating; duplicate output pins must both be connected for proper operation. |
| 8 | VDD | power_in | Bias supply for the MOSFET driver, rated 4.5V to 25V with respect to the Ground pin; duplicate VDD pins must both be connected for proper operation. |
