PRESS RELEASE
DATA SHEET
The new AUIRS2332J is a 600V three-phase gate
driver IC for automotive high-voltage motor
drives for electric (EV) and hybrid electric
vehicle (HEV) applications. With its high level
of integration and comprehensive set of
protection features, the AUIRS2332J simplifies
and shrinks design while providing the
reliability and ruggedness required for EV and
HEV motor drive or inverter applications.

• Advantages
• The AUIRS2332J, high-voltage, high-speed power
  MOSFET and IGBT driver features three independent
  high- and low-side referenced output channels.
• Proprietary HVIC technology enables ruggedized
  monolithic construction with logic inputs
  compatible with CMOS or LSTTL outputs down to
  3.3V logic.
• The new device also offers an integrated
  ground-referenced operational amplifier to
  provide analog feedback of the bridge current via
  an external current sense register, current trip
  function, and open drain FAULT signal to indicate
  over-current or under-voltage shutdown.
• The IC is housed in a PLCC44 package, providing
  higher creepage distances between high voltage
  pins, simplifying PCB layout.
