Dioo launches DIA74H120, 4-channel 120mΩ intelligent high-side switch

     One hundred years of automotive development, the wave of intelligence is constantly reconstructing automotive products and the entire automotive industry chain, in this process, the high-side switch as a key electronic component, the application of automotive systems is more and more extensive. On the one hand, with the increase of automation functions, the load points on the vehicle are also increasing, thus increasing the demand for high-side switches.

     On the other hand, as the level of intelligent driving improves, traditional fuses and relays are gradually replaced by high-side switches. Fuse and relay as a common switching method, the advantage is low cost, but can not achieve complex protection and diagnostic functions, in the face of increasingly complex needs, its limitations have become more obvious, at this time, the choice of high-performance high-side switch is an optimal solution.

     Dioo's latest four-channel 120mΩ intelligent high-side switch DIA74H120 can replace traditional fuses and relays well, and is used for extraordinary power distribution in body area controllers, driving some small power controllers, such as incense controllers, PM2.5, millimeter-wave radar, integrated inertial navigation, etc. Compared to traditional switches, the DIA74H120 has complete fault diagnosis and protection functions, high-precision current detection, higher reliability and the possibility of restart.

     When driving different types of loads, the DIA74H120 provides excellent protection against short circuits, overcurrent and overheat. In addition, the DIA74H120 can also be used for the POC power supply of the camera, the high and low side control of the high voltage relay in the BMS system, a variety of interior small lights, and the driver of the indicator light.
