gate driveroptocouplerIGBTMOSFETDESATUVLOSOP16

AT331J-CuH-S is a 16-pin isolated gate driver optocoupler for IGBT and MOSFET switching stages, with DESAT protection, UVLO and active Miller clamp.

Best for

  • Isolated IGBT gate-drive stages
  • Isolated MOSFET gate-drive stages
  • Industrial inverter and motor-control power stages

Avoid if

  • A non-isolated or logic-level-only gate driver is required
  • The design requires verified lifecycle or supply guarantees not present in the supplied data

Check before use

  • Confirm the latest DESAT threshold and pin-function documentation
  • Confirm gate-charge current, switching frequency and output IC power dissipation
  • Verify creepage, clearance and isolation implementation on the PCB
