Summary points:

  • Littelfuse introduces the AEC-Q100-qualified IX4352NEAU low-side gate driver optimized for SiC MOSFET and IGBT control in EV inverters, DC-DC converters, and motor drives.
  • Built-in adjustable negative gate drive bias eliminates the need for external DC-DC converters, simplifying design and reducing total system cost.
  • Offers improved switching efficiency, higher power density, and robust operation across wide temperature ranges for demanding automotive applications.

ROSEMONT, Ill. – Littelfuse Inc. in Rosemont, Ill., is introducing the IX4352NEAU automotive-qualified low-side gate power driver for silicon carbide metal oxide field effect transistor (MOSFET) and insulated-gate bipolar transistor (IGBT) control in switching power supplies; automotive DC-DC converters; and EV inverters and motor drives.

The IX4352NEAU is an AEC-Q100-qualified low-side gate driver with an integrated and adjustable negative gate drive bias to eliminate the need for an external negative voltage rail or the costly DC-DC converters typically required to suppress parasitic turn-on of high-speed power devices.

This can simplify gate driver design, improve switching performance, and reduce total system cost for systems that use MOSFETs and IGBTs.

Fast turn-off

The IX4352NEAU power electronics device offers adjustable negative gate drive bias to improve dv/dt immunity, suppress parasitic turn-on, and ensure fast turn-off of SiC MOSFETs and IGBTs. It enables tailored turn-on and turn-off timing to optimize efficiency and reduce switching losses.

The device tolerates as much as seven volts to enable easy interfacing with most control logic. It ensures consistent performance across a wide temperature range, with improved thermal threshold accuracy and charge pump operation maintained during thermal shutdown.

Compared to conventional low-side gate drivers, the IX4352NEAU increases power density, reduces component count, and provides a safer overcurrent turn-off transition.

The IX4352NEAU is an automotive-grade extension of the commercial-grade IX4352NE for strict reliability and performance demands. For more information contact Littelfuse online at www.littelfuse.com.
