The L6388D is a 3-phase gate driver IC with integrated pre-drivers, designed to drive the gates of any high current half-bridge or three-phase IGBT, such as MOSFET, N-channel MOSFET, unipolar transistors, and other types. It can also be used effectively with half-bridge modules.

The primary application field of L6388D is motor control, whether it\'s for industrial, automotive, appliance or aviation requirements. Smart systems demands for integrated solutions for the motor control systems, which is the reason why L6388D can provide them with the perfect solution. The L6388Dprovides a comprehensive set of features that can easily handle advanced motor control systems, in addition to its compact package size.

The power stages of the L6388D are composed of one driven high side FET and one non-driven low side FET, and both of them could be tailored so that they can handle high current applications. Filter capabilities, such as ESD on outputs, integrated diodes for effective body diode protection to high-side FETs, and integrated ESD diodes on the gate drivers of the high-side FETs, are also the features incorporated to the L6388D.

The L6388D also features a built-in thermistor protection and overcurrent protection, in addition to its typical protection features we already mentioned. This product is designed to work with a wide range of voltages (5V to 28V) and can be configured to operate at several different levels of current.

The working principle of the L6388D is very simple and straight-forward. The main purpose of the device is to boost the available current and then spread it to the power stages, so that they can handle higher currents. The power stages are driven by the gate drivers, which are isolated and protected with integrated diodes and ESD protection, and the gate driver current is spread across the power stages.

The L6388D also includes an integrated fault reporting system. This system monitors for any overcurrent conditions present, and it will also monitor for circuit protection activated to help protect the power stage from damage. This feature makes the device a great option for motor control applications, as it helps ensure the optimal performance of the motor.

In summary, the L6388D is a comprehensive 3-phase gate driver IC with integrated pre-drivers, designed to drive the gates of any high current half-bridge or three-phase IGBT. It is mainly used for motor control applications due to its simplicity, accuracy, and dependability. Additionally, its intelligent fault-reporting system and robust power stages makes it an excellent choice for advanced motor control systems.
