CISSOID Delivers Robust Gate Drivers For Industrial Applications


  • CISSOID has developed robust Gate Drivers for XM3 SiC MOSFET power modules
  • It offers fast switching of SiC MOSFETs up to 50KV/µs that helps in improving efficiency and reducing the size of power converters

A gate driver with higher drive capability enables fast switching. It features rising and falling time of few nanoseconds. This, as a result, reduces the switching power loss and leads to a more efficient system. Hence, drive current is usually considered to be an important parameter in the selection of gate drivers.

Designed for fast switching MOSFETs

CISSOID has developed a new gate driver for SiC Mosfet modules. According to the company, this new gate driver board is able to safely drive the fast switching SiC power modules. Gate drivers need fast switching to achieve low losses and to operate in high-temperature environments.

Used HADES gate driver chipset


According to the company, these power modules are rated at a temperature of 125°C (Ta). These boards are based on CISSOID HADES gate driver chipset. It offers enhanced thermal properties. It enables high operating frequency above 100KHz. It offers fast switching of SiC MOSFETs up to 50KV/µs. Thus, it helps in improving efficiency and reducing the size of power converters.

Features an on-board power supply

The CMT-TIT0697 Gate Driver board has been designed to be directly mounted on CAB450M12XM3 1200V/450A SiC MOSFET Power Modules. It features an onboard isolated power supply that can deliver a power of up to 2.5W per channel. It does so without decreasing the efficiency up to a temperature of 125°C.

Peak gate current of up to 10 A

The driver can sustain a peak gate current of up to 10A. This makes it possible to drive the power module with zero gate resistance. It hence achieves minimum switching losses. The board is able to withstand isolation voltages of up to 3600V (50Hz, 1min).

New Signage LEDs Fit Indoor & Outdoor Applications

Features circuit protection modules  

The driver offers a creepage distance of 14mm. It is also equipped with circuit protection functions such as under-voltage lockout (UVLO), Active Miller Clamping (AMC), Desaturation detection and Soft-shut-down (SSD). This ensures reliable protection of power modules in the case of fault events.

With all these features, this driver can help in designing high-density power converters. These converters can be used in automotive and industrial applications. These drivers can be largely used in space-constrained motor drives, compact power supplies or fast battery chargers.
