Overview
The L6388ED013TR, produced by STMicroelectronics, is a high-voltage gate driver designed to drive a half-bridge of power MOSFET/IGBT devices. Manufactured using the BCD™ “offline” technology, this device is capable of handling high voltage rails up to 600 V. It features two input and two output pins, ensuring that the outputs switch in phase with the inputs. The logic inputs are CMOS/TTL compatible, supporting 3.3 V, 5 V, and 15 V, which facilitates easy interfacing with controlling devices. The integrated bootstrap diode enhances the compactness and reliability of the driver. Additionally, the device includes UVLO protection on both supply voltages (VCC and VBOOT) to safeguard against voltage drops on the supply lines.
