Overview
The L6392D, produced by STMicroelectronics, is a high voltage device manufactured using the BCD™ “offline” technology. It is designed as a single chip half bridge gate driver for N-channel power MOSFETs or IGBTs. The device features a high-side (floating) section capable of handling voltage rails up to 600 V, making it suitable for various high-voltage applications. The logic inputs are CMOS/TTL compatible down to 3.3 V, facilitating easy interfacing with microcontrollers or DSPs. The IC also includes an operational amplifier for advanced current sensing, particularly useful in field-oriented motor control applications.
