Gate Drivers

gate-drive optocouplerIGBT driverMOSFET driverSOP6-Wreinforced isolation

AT343-CuH-W is an isolated SOP6-W gate-drive optocoupler for IGBT and MOSFET applications, offering up to 4.0 A peak output drive and a 15 V to 30 V output-side supply range.

Best for

  • IGBT and MOSFET gate-drive circuits
  • Isolated motor-control inverter stages
  • Industrial and renewable-energy power converters

Avoid if

  • A verified lifecycle or RoHS/REACH declaration is mandatory but unavailable
  • The application requires a package other than SOP6-W
  • Gate-drive requirements exceed the specified output capability

Check before use

  • Confirm gate-charge and external gate-resistor switching performance
  • Place output-side bypass capacitance close to VDD and VSS
  • Check isolation coordination for the system working voltage
