STMicroelectronics STGAP2SICS single gate driver for SiC MOSFETs

The STGAP2SICS is a 6 kV single gate driver that provides galvanic isolation between the gate driving channel and the low voltage control and interface circuitry. It is characterized by 4 A capability and rail-to-rail outputs, and is available in two different configurations:

• Separated output pins to allow independent optimize turn-on and turn-off by using dedicated gate resistors
• Single output pin and Miller CLAMP function to prevent gate spikes during fast commutations in half-bridge topologies

Key features

• 1200 V, 4 A sink/source capability
• 6 kV galvanic isolation
• Miller CLAMP dedicated pin option
• UVLO & Watchdog functions

Additional features

• High voltage rail up to 1200 V
• Driver current capability: 4 A sink/source at 25 °C
• dV/dt transient immunity ±100 V/ns over the full temperature range
• Overall input-output propagation delay: 75 ns
• Separate sink and source option for easy gate driving configuration
• 4 A Miller CLAMP dedicated pin option
• UVLO function
• Gate driving voltage up to 26 V
• 3.3 V, 5 V TTL/CMOS inputs with hysteresis
