Microchip expands mSiC solutions to accelerate adoption of SiC power modules

With the widespread adoption of Silicon Carbide (SiC) technology in medium-to-high-voltage applications, Microchip Technology has now introduced the 3.3 kV XIFM plug-and-play mSiC gate driver.

The device, with patented Augmented Switching technology, is designed to work out-of-the-box with preconfigured module settings to significantly reduce design and evaluation time.

With complex development work such as designing, testing and qualifying the gate driver circuit design already completed with this plug-and-play solution and by also having the gate drive circuitry preconfigured, this solution can reduce design cycle times by as much as 50% compared to a traditional analogue solution.

The XIFM digital gate driver is compact and features digital control, an integrated power supply and a fibre-optic interface that improves noise immunity. This gate driver has preconfigured “turn-on/off” gate drive profiles that are tailored to optimise the module's performance.

It also incorporates 10.2 kV primary-to-secondary reinforced isolation with built-in monitoring and protection functions including temperature and DC link monitoring, Undervoltage Lockout (UVLO), Overvoltage Lockout (OVLO), short-circuit/overcurrent protection (DESAT) and Negative Temperature Coefficient (NTC).

This gate driver complies with EN 50155, which is a key specification for railway applications.
