It is a single-chip half-bridge gate driver for N-channel power MOSFET or IGBT. The high-side (floating) section is designed to stand a voltage rail up to 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing the microcontroller/DSP. An integrated comparator is available for protections against overcurrent, overtemperature, etc. September 2015 This is information on a product in full production.
