The L6384D013TR is a high-performance gate driver IC designed to drive power IGBTs and MOSFETs in high power applications. This device has been designed to provide high driving capability, low quiescent current, low parasitic capacitance, high immunity to noise, and a wide operational temperature range. Due to its fast switching speeds, it can also be used to drive relays, solenoids and other inductive loads. The L6384D013TR is classified among Power Management ICs (PMICs) as a Gate Driver.

Applications

The L6384D013TR can be used in various power management applications. Some examples include:

• Motor control systems, including Brushless DC Motors (BLDC Motors), electrical steering motors and traction inverters.
• Switched-mode power supplies (SMPS) and uninterruptible power supplies (UPS).
• Electro-mechanical actuators.
• Solar inverters and power modules.
• High-fidelity audio amplifiers.
• Industrial and consumer appliances.

Working Principle

The L6384D013TR is an isolated dual-gate driver, which is designed to drive two power IGBTs or MOSFETs independently. It integrates two channels of high-side and low-side gate driver outputs, each with a maximum peak output current capability of up to 7A. The L6384D013TR also includes two integrated buck converters, with a minimum input voltage of 4.5V.

The L6384D013TR has a built-in delay circuit to ensure that both the high-side and low-side gate drivers are triggered at the same time. This ensures that the IGBTs are switched on or off in a balanced manner, reducing power dissipation and excessive stress on the device.

The L6384D013TR also includes a slew rate control circuit which is used to adjust the gate driving voltage level of the IGBT. This reduces the switching speed of the gate driver, reducing the power losses caused by the IGBT gate charge.

The L6384D013TR is also equipped with built-in Over-Temperature (OT) protection and Under-Voltage Lockout (UVLO) protection for the buck converter. This protects the device from damage caused by excessive load currents or sudden voltage changes.

Key Features

• Maximum peak output current of 7A.
