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 microcontroller/DSP. An integrated comparator is available for fast protection against overcurrent, overtemperature, etc. Table 1.
