Overview
The L6385E, specifically the L6385ED013TR model, is a high voltage gate driver manufactured by STMicroelectronics using BCD™ “offline” technology. This device is designed to drive a half-bridge of power MOSFET or IGBT devices. It features a high-side (floating) section capable of operating with a voltage rail up to 600 V. The L6385E provides two input pins and two output pins, ensuring that the outputs toggle in phase with the inputs. The logic inputs are CMOS/TTL compatible, facilitating easy interfacing with controlling devices. The integrated bootstrap diode enhances the compactness and reliability of the device. Additionally, the L6385E includes undervoltage lockout (UVLO) protection on both the lower and upper driving sections to protect against voltage drops on the supply lines.
