Description

The STGAP2SiCS is an isolated single gate driver.

The gate driver is characterized by 4 A current capability and rail-to-rail outputs,

making the device also suitable for high power inverter applications such as motor

drivers in industrial applications equipped with SiC MOSFET power switches.

The configuration featuring single output pin and Miller CLAMP function allow

avoiding gate spikes during fast commutations in half-bridge topologies.

The device integrates protection functions: UVLO and thermal shut down are

included to easily design highly reliable systems. Dual input pins allow choosing the

control signal polarity and also implementing HW interlocking protection in order to

avoid cross-conduction in case of controller malfunction.

The device allows implementing negative gate driving, and the on board isolated DC-

DC converters allows working with optimized driving voltage for SiC MOSFET.

The EVALSTGAP2SiCSC board allows evaluation of all the STGAP2SiCSC features

while driving a half-bridge power stage with voltage rating up to 1200 V in TO-220 or

TO-247 packages.

The board components are easy to access and modify in order to make driver

performance evaluation easier under different application conditions and fine

adjustment of final application components.
