Microchip expands its mSiC solutions

To speed time to market, the complex development work of designing, testing and qualifying a gate driver circuit design is already completed with this plug-and-play solution. The XIFM digital gate driver is a compact solution that features digital control, an integrated power supply and a robust fibre-optic interface that improves noise immunity. This gate driver has preconfigured “turn-on/off” gate drive profiles that are tailored to optimise module performance.

It 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 also complies with EN 50155, a key specification for railway applications.

“As the silicon carbide market continues to grow and push the boundaries of higher voltage, Microchip makes it easier for power system developers to adopt wide-bandgap technology with turnkey solutions like our 3.3 kV plug-and-play mSiC gate driver,” said Clayton Pillion, vice president of Microchip’s silicon carbide business unit. “By having the gate drive circuitry preconfigured, this solution can reduce design cycle time by up to 50% compared to a traditional analog solution.”
