Interface - Drivers, Receivers, Transceivers

The DJLXT381LE.B4 is a high performance dual channel FET driver designed for driving MOSFET and IGBT gates. This type of device is commonly used in areas such as robotic control, motor controllers, and system interconnects. The DJLXT381LE.B4 can also be used in industrial applications such as controlling valves and machines. It offers two 18V outputs, a high and low output, with a total of 40V peak-to-peak and 6W of power.

Application Field

The DJLXT381LE.B4 is suitable for a variety of applications. It has two outputs, a high and low output, which can be used for gate drive signals in MOSFET and IGBT power devices. It is commonly used in robotic motor control, system interconnects, and valve and machine controllers. It is also used as a dual channel FET driver in systems requiring high voltage and power control.

The device is capable of controlling both high and low-side components with a single sided supply, making it also suitable for small and compact applications. Furthermore, due to its bi-directional structure, the DJLXT381LE.B4 can be used in two applications: as a high-side driver for positive logic operations and a low-side driver for negative logic operations.

The device is also designed to minimize board space and minimize loading effects of the gate drive circuit, which eliminates the need for bulky external components.

Working Principle

The DJLXT381LE.B4 is a dual-channel FET driver that is designed to drive MOSFET and IGBT gates. It works by providing two outputs, a high and a low, which can be used to drive the gates of the MOSFET and IGBT devices. The output of the high-side driver is typically connected to the gate of the MOSFET or IGBT device and the output of the low-side driver is connected to the contra-gate.

These two outputs are then used to turn the device on and off, as well as adjust its speed or current. The high output is typically connected to the gate of the device and a voltage applied across it. When the voltage is positive, the device turns on and when it is negative, the device turns off. The low output is used to adjust the speed or current of the device.

The DJLXT381LE.B4 also includes an on-board voltage regulator, which ensures that the drive signal is maintained at a stable and consistent level. This voltage regulator also assists with reducing any noise associated with the drive signal, allowing for smooth and reliable operation.

The device also supports internal protection circuits, allowing it to withstand inrush currents that can be caused by short circuit or overloading. This ensures the device is safe to use and its operation remains reliable. Additionally, the device is capable of supporting up to 6W of power.
