HCOS4426SR

HXY MOSFET · Gate Drivers · SOP-8

HCOS4426SR from HXY MOSFET, 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 Marked as an empty (no-connect) pin in the datasheet pin table; the datasheet advises tying unused pins to VCC or GND in noisy environments.
2 INA input Channel A input with logic thresholds of VIH 2.4 V minimum and VIL 0.8 V maximum, and it tolerates -10 V to VCC+0.3 V absolute input voltage.
3 GND power_in Ground reference for all voltage parameters; the device tolerates noise spikes up to 5 V of either polarity on the ground pin without damage.
4 INB input Channel B input with logic thresholds of VIH 2.4 V minimum and VIL 0.8 V maximum, and it tolerates -10 V to VCC+0.3 V absolute input voltage.
5 OUTB output Channel B output, inverting with respect to INB, able to source or sink 2 A peak current to drive a P- or N-type MOSFET gate.
6 VCC power_in Supply pin with recommended operating range 4.5 V to 20 V and absolute maximum of 25 V, referenced to GND.
7 OUTA output Channel A output, inverting with respect to INA, able to source or sink 2 A peak current to drive a P- or N-type MOSFET gate.
8 NC unconnected Marked as an empty (no-connect) pin in the datasheet pin table; the datasheet advises tying unused pins to VCC or GND in noisy environments.
