L6387ED013TR is a gate driver designed and produced by STMicroelectronics. It is a self-contained, low cost, robust integrated power module that provides high-voltage insulation and is ideally suited for the most demanding applications. The module includes the L6387ED013TR gate driver, a power MOSFET, and external current sense resistor, making it an all-in-one solution for driving high-current, high-voltage loads. It is also easy to integrate, with a minimal number of components, and offers a wide range of features including over-current protection, over-voltage protection and wide operating temperature ranges.

The L6387ED013TR gate driver is suitable for driving power MOSFETs with high power up to 80 V. It has a wide operating temperature range, from -40 °C to +125 °C, and a high-voltage endurance rating of up to 200 V. The module can be used in motor control, inverters, motor drives, UPS and industrial automation applications.

The main purpose of a gate driver is to provide a gate drive voltage of the appropriate magnitude and phase to turn on a power MOSFET at the gate terminal. If the voltage applied to the gate terminal is not sufficient, the MOSFET may not turn on or turn off completely, resulting in an increased power consumption and voltage drop across the MOSFET. The L6387ED013TR gate driver provides a high-current gate drive voltage of up to 8 A, which is sufficient to turn on a wide range of MOSFETs. In addition, the module has the capability to sense the voltage at the load terminal and disconnect it in the event of an over-voltage or short circuit condition.

The working principle of the L6387ED013TR gate driver is simple. It uses an external voltage divider to reduce the voltage at the gate terminal of the MOSFET. Then, an internal comparator compares the voltage at the gate terminal to the reference voltage, and if the gate voltage is lower than the reference voltage, the gate driver will turn on the power MOSFET. The module will also detect the presence of an external current sense resistor and disconnect the load in the event of an over-current situation.

The L6387ED013TR is a high-performance gate driver that is ideal for high-power, high-voltage loads. It provides a wide operating temperature range and high-voltage endurance, and can be used in a variety of applications, such as motor control, inverters, motor drives, UPS, and industrial automation. The module is also easy to integrate, with a minimal number of components, and offers a wide range of features including over-current and over-voltage protection.
