Overview
The L6387DTR, produced by STMicroelectronics, is a high-voltage half-bridge gate driver designed for driving independent referenced N-channel power MOSFETs or IGBTs. This device is manufactured using the BCD "OFF-LINE" technology, enabling it to handle high voltage rails up to 600 V. The L6387DTR features CMOS/TTL compatible logic inputs, making it easy to interface with controlling devices. It includes an internal bootstrap diode and driver structure that simplifies the design and reduces the need for external components.
