Overview
The L6395D, produced by STMicroelectronics, is a high voltage device manufactured using the BCD™ “offline” technology. It is a single-chip high and low-side gate driver designed for N-channel power MOSFETs or IGBTs. The device features a high-side (floating) section capable of withstanding a voltage rail 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.
