Description This reference design is an automotive qualified isolated gate driver solution for driving Silicon Carbide (SiC) MOSFETs in half bridge configuration. The design includes two push pull bias supplies for the dual channel isolated gate driver respectively and each supply provides +15V and -4V output voltage and 1W output power. The gate driver is capable of delivering 4A source and 6A sink peak current. It implements reinforced isolation and can withstand 8kV Peak and 5.7kV RMS isolation voltage and >100V/ns common mode transient immunity (CMTI). The reference design contains the two-level turn-off circuit which protects the MOSFET from voltage overshoot during the short circuit scenario. The DESAT detection threshold and the delay time for second stage turn-off are configurable. The ISO7721-Q1 digital isolator is implemented for interfacing the signals of fault and reset.

MOSFET T1 between Gate and Source of the FMF800DX-24A is turned-on over a large gate resistor value, which keeps the level of the turn-on resistance of the MOSFET relatively high. Thus a soft discharge or Soft Shut Down (SSD) of the SiC-Gate is realized. TI helps you find the right MOSFET & IGBT gate drivers for your system design using a wide variety of commonly used parameters and specifications.

Agileswitch SiC MOSFET Gate Drivers Switching a SiC MOSFET Power Module creates two significant problems that need to be addressed to optimize the performance of the device: turn-off spikes and ringing. These two parasitic problems need to be controlled while maintaining efficient switching. AgileSwitch has developed a patent-pending line of programmable Gate Drive Boards (GDBs) that address these problems, controlling the turn-off di/dt by varying the gate voltage level and dwell time to one or more intermediate levels during turn-off. This process is typically referred to as Augmented Turn-Off or ATOff. In addition, AgileSwitch software configurable GDBs report out 7 unique fault conditions along with Temperature and DC Link Voltage. The combination of these effects will help drive growth in adoption of SiC devices, and the inverters that they support.
