Overview
The L6393DTR, produced by STMicroelectronics, is a high-voltage half-bridge gate driver IC manufactured using the BCD™ “offline” technology. This single-chip device is designed to drive N-channel power MOSFETs or IGBTs. The high-side (floating) section of the L6393DTR can withstand a voltage rail up to 600 V, making it suitable for 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 uncommitted comparator for protections against overcurrent, overtemperature, and other potential issues.
