CMT-TIT8244

1700V Half-Bridge SiC MOSFET Gate Driver

CMT-TIT8244 is Gate Driver board optimized for 62mm Silicon Carbide (SiC) MOSFET Power Modules rated at 125°C (Ta). This board, based on CISSOID HADES gate driver  chipset, offers thermal headroom for the design of high density power converters in automotive and industrial applications. It enables high frequency (>100KHz) and fast SiC MOSFET’s switching (dV/dt>50KV/µs), improving efficiency and reducing size and weight of the power converters.

The board is designed for harsh voltage environments supporting the drive of 1700V power modules with isolation voltages up to 3600V (50Hz, 1min) and creepage distances of 14mm. Protection functions such as undervoltage lockout (UVLO), Active Miller Clamping (AMC) and Desaturation detection ensure the safe drive and reliable protection of the power module in case of fault events.
