L6391数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

The L6391 is a high voltage device manufactured with the BCD™ “OFF-LINE” technology. 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.
