With the rapid upgrading of automobile electrification and intelligent system,the stability,safety and intelligent capability of the chip are increasingly demanded by vehicle load control.Analog domestic self-developed HD70xx2Q dual-channel high-side driver chip for vehicle gauge is an intelligent high-side switch suitable for vehicle 12V grounding load scene.With the advantages of high integration,all-round protection and accurate diagnosis,it has become the preferred core equipment of vehicle electronic control system,which perfectly meets various vehicle electronic control requirements.
 

The analog high-side driver chip HD70xx2Q is equipped with exclusive multi-function multiplexed analog output CS pin,equipped with omni-directional diagnosis system,and supports high-precision real-time detection of load current,which can accurately identify bad working conditions such as excessive output load,short circuit to ground,short circuit to VCC,and has the ability to check off-state open-circuit load.The SEn detection enable pin on the high-side driver chip can flexibly switch the diagnostic function module,and the power consumption of the whole machine can be reduced by turning off the diagnostic mode when idle.In the scenario of multi-chip combination,the chip only needs a single ADC sampling channel and a single CS resistance to ground to complete signal acquisition,which greatly optimizes the system architecture and reduces the cost of batch application.
 

The high-side driver chip integrates multiple protection mechanisms to ensure the stable operation of the vehicle-mounted system in all directions.Covers VCC under-voltage shutdown,over-voltage clamping and VDS negative pressure clamping protection,and is equipped with intelligent thermal shutdown alarm,graded over-temperature protection and precise over-current protection function modules.In view of the special working conditions of the vehicle,the chip also supports the protection of grounding loss,automatic shutdown of VCC loss system and battery reverse connection,which comprehensively resists various problems such as abnormal voltage,excessive temperature load and circuit failure,and greatly improves the safety and service life of the vehicle-mounted equipment.
 

With the solid quality of car gauge,perfect diagnostic protection function and high adaptability,the analog semiconductor HD70xx2Q domestic car gauge dual-channel high-side driver chip can be widely used in all kinds of vehicle 12V load control scenarios,which is a highly reliable and low-cost vehicle power drive solution.As an agent of analogy,we can provide a complete set of mature high-side drive solutions to help upgrade the localization of industrial equipment and meet the customized development needs of multi-scene automation equipment.If you need high-side driver chips,please feel free to contact us.
