Littelfuse Gate Drivers

Find the right driver to fit your application

Count on efficient switching up to 600 V with the extensive Littelfuse portfolio of half-bridge gate drivers which combine speed with high performance, and eight different high-side, low-side gate drivers to give you the flexibility to find the driver to fit your application.

If you are driving silicon carbide (SiC) MOSFETs and IGBTs, there are new low-side drivers which add the option of automotive qualification.


3 Phase Half-Bridge Drivers

LF2136 and LF2388

Littelfuse – 3 Phase Half Bridge Drivers

The LF2136 and LF2388 devices are 3-phase gate drivers that efficiently switch three pairs of N-Channel MOSFETs or IGBTs in 6-pack configurations. The gate drivers convert the controller’s PWM signals into gate-signals compatible to MOSFETs or IGBTs, providing a robust and reliable power semiconductor control. 

Features

  • Three floating high-side drivers in bootstrap operation to 600V
  • 350mA/200mA and 600mA/290mA Sink/Source Output Capability
  • Undervoltage Lockout and Overcurrent Protection
  • Internal deadtime generation
  • Matched propagation delay for all channel

Applications

  • 3-phase motor inverters
  • White goods
    • Washing machine
    • Refrigerator
  • Air conditioner
  • Cordless power tools
  • Robotics

Low-side driver for driving SiC MOSFETs and IGBTs with AEC-Q100 option

IX4351 and IX4351NEAU

Littelfuse – Silicon Carbide Gate Driver

The IXYS IX4351NE and automotive-grade IX4351NEAU, from Littelfuse, are 9 A low-side drivers for driving silicon carbide (SiC) MOSFETs and high-power IGBTs. The optimized turn-on and turn-off timing of the drivers is enabled by the separate 9 A source and sink outputs, and switching losses are also minimized.

Features

  • Separate 9 A peak source, sink outputs
  • Voltage range: -10 V to 25 V
  • Internal negative charge pump regulator
  • Selectable negative gate drive bias
  • Desaturation detection
  • TTL and CMOS compatible input
  • Under-voltage lockout
  • Thermal shutdown
  • Open drain FAULT output
  • AEC-Q100-qualified option

Applications

  • Driving SiC MOSFETs or IGBTs
  • Automotive
