Product:  Automotive-grade Dual-channel Intelligent High-side Switch HD70152Q 

Description

HD70152Q is an automotive-grade dual-channel intelligent high-side switch. Its input control pins are compatible with 3V and 5V CMOS interfaces, and it is equipped with two independent output channels. The HD70152Q is widely used in automotive 12V grounded load applications, which can further provide intelligent protection and diagnostic functions. HD70152Q integrates advanced protection functions, including load over-current limit protection, relative over-temperature protection, and over-temperature shutdown protection with configurable latch function. The pin of HD70152Q can control the output automatic recovery or output blocking when a fault occurs. In addition, HD70152Q can survive of abnormal application scenarios like reverse battery and loss of ground. HD70152Q internally integrates a dedicated multi-function multiplexing analog output pin CS, which can provide complex diagnostic functions, including high-precision proportional load current detection, output overload, ground short-circuit alarm, VCC short-circuit diagnosis and OFF state open circuit diagnosis. The maximum standby current of HD70152Q is only 0.01uA. The input SEn pin is the detection enable pin of HD70152Q, which can further disable the diagnostic function in the OFF state to obtain lower power consumption. In addition, in the scenario where multiple HD70152Qs are used in the same system, in addition to saving power consumption, SEn can also realize that multiple HD70152Qs only need one ADC sampling channel and one CS resistance to ground, which greatly optimizes the system implementation cost.

Unique advantages

By adopting innovative circuit and package designs, this part solves the problem of strict control of supply voltage, temperature and power consumption that are required in automotive applications.

Application

Implement in the body control system to drive the resistive load like the ambient light, Taillight, turn light, reversing light. Inductive load like the heating coil, cable, latch and electro valve. Capacitive load like power distribution and the halogen lamp.

Prospect

With the quick high-speed development of the automotive electronization, the traditional relay solution is taken placed by the electrical high side driver gradually in the every components in automotive. There are 50~100 channel of the high side driver required in a care in average, which is dominated by the western company with the lower localization rate, particular in the high side driver with the higher power. So, for the local semiconductor brand, there will be a huge space for local semiconductor to develop no matter in the incremental market of the new-energy automotive and the existing stock market dominated by the western semiconductor.
