IX4351 from IXYS: A Littelfuse Technology
The IXYS IX4351 evaluation board from Littelfuse demonstrates the capabilities of the IX4351 SiC MOSFET Gate Driver in conjunction with a Littelfuse SiC MOSFET.
The IX4351 low side driver is powered by a 13V to 25V supply and has separate 9A source and sink outputs for customizable turn-on and turn-off timing with minimal switching losses. The driver integrates desaturation detection circuitry that initiates a soft turn off of the MOSFET if it detects an overcurrent condition, preventing potential damage to the MOSFET.
The IX4351 also has a negative charge pump regulator for selectable gate drive bias and faster turn off, and is compatible with 3.3V and 5V logic for easy interfacing. The board includes a 1200V Littelfuse SiC MOSFET that can switch 25A and has a typical RDS,ON rated at 80mΩ.
It also has an optically isolated interface for the PWM input and the fault indicator output, with the isolators powered by a 3.3V or 5V supply.
