Littelfuse — Gate Drivers

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

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.

High-Side / Low-Side Gate Drivers

LF2106, LF2181, LF2190, LF21064, LF21814, LF21904, LF2110, LF2113

High voltage, high speed High-Side and Low-Side Gate Drivers are efficiently driving two N-Channel MOSFETs or IGBTs. The floating high-side switch is operated in bootstrap configuration up to 600VDC. The logic inputs are compatible to standard TTL and CMOS levels down to 3.3V. 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.

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

IX4351 and IX4351NEAU

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.
