ISL6146DFRZ-T is a multi-channel PMIC-OR controller with integrated ideal diodes, which is a solution for high-voltage free-wheeling applications. It is designed to reduce system cost and component count while providing better transient performance than standard products. The device provides high-voltage transient protection with integrated ideal diodes and operates in both synchronous and asynchronous modes. 

Application Field

ISL6146DFRZ-T is used in PMIC (Power Management Integrated Circuit) applications and is suitable for high-voltage applications. It can be used in automotive, industrial, and consumer applications, such as motor control, photovoltaic applications, and lighting. Its ability to protect sensitive components from high transient voltages makes it ideal for power-sensitive devices. 

Working Principle

ISL6146DFRZ-T’s working principle is based on the PMIC-OR controller’s ability to switch between a synchronous and an asynchronous mode of operation. In synch mode, the device turns on one MOSFET switch, which causes current to flow in one direction. When the current reaches its peak, the device switches to an asynchronous mode and both MOSFET switches are turned on simultaneously. The current then flows in both directions which allows it to return to zero and filter transients. In addition, the device has integrated ideal diodes, which further reduce the voltage transients. 

ISL6146DFRZ-T is a highly efficient PMIC-OR controller solution with integrated ideal diodes, which makes it an ideal solution for high-voltage applications in automotive, industrial, and consumer applications. Its ability to switch between synchronous and asynchronous modes and its integrated ideal diodes make it an efficient solution for transient protection.
