L6388ED013TR Introduction

A popular half-bridge gate driver IC in power electronics applications is the L6388ED013TR. It is intended to operate in half-bridge arrangements to drive N-channel MOSFETs and IGBTs. A non-inverting arrangement is one of the IC’s primary advantages, making it useful for various applications, including motor control, power supplies, and lighting systems. The L6388ED013TR will be thoroughly covered in this article, including its features, applications, operational requirements, and circuit design concerns.

L6388ED013TR Description

The L6388E is a high-voltage gate driver that can power a half-bridge of MOSFET/IGBT devices using the BCD TM “offline” manufacturing technique. It is possible for the high-side (floating) part to operate with voltage rails up to 600 V. Due to an integrated interlocking feature, none of the device’s outputs may be simultaneously driven high; each can sink and source 650 mA and 400 mA, respectively. The deadtime function ensures further protection against output cross-conduction.

The L6388E gadget ensures that outputs transition in phase with inputs and includes two input and two output pins. The CMOS/TTL-compliant logic inputs (3.3 V, 5 V, and 15 V) make an interface with controlling devices simpler. Because the bootstrap diode is built into the driver, a more dependable and portable approach is possible. Greater protection against voltage drops on the supply lines is provided by the L6388E device’s UVLO protection on both supply voltages (VCC and VBOOT). The device is offered in packaging types, including tape and reel, DIP-8, and SO-8 tubes.
