The STDRIVEG600 is a single chip half-bridge gate driver for Enhancement mode GaN FETs or N-channel power MOSFET.

The high-side section is designed to stand a voltage up to 600 V and is suitable for designs with bus voltage up to 500 V.

The device is designed for driving high-speed GaN and Si FETs thanks to high current capability, short propagation delay and operation with supply voltage down to 5 V.

The STDRIVEG600 features UVLO protection on both the lower and upper driving sections, preventing the power switches from operating in low efficiency or dangerous conditions, and the interlocking function avoids cross-conduction conditions.

The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing with microcontroller and DSP.
