HD70402Q Automotive Dual-Channel 40mΩ Smart High-Side Driver
●The HD70402Q is an automotive dual-channel smart high-side driver. It features 3V/5V CMOS compatible input control interface and two independent output channels. It can also provide smart protections and diagnostics. The HD70402Q is extensively used in 12V automotive power supply systems.
●The HD70402Q integrates advanced protection functions, including overcurrent limit protection, and dynamic overtemperature protection. Additionally, HD70402QASSOP16P provides con- figurable output latch/auto-retry function though the FaultRST pin when thermal shutdown or over-current event occurs.
●The HD70402Q also integrates a multiplexed analog output through the CS pin to provide complex diagnostic functions, including accurate analog output proportional to loading current, overload and output short to ground alarms, output short to VCC, and open load detection in OFF state.
●The HD70402Q SEn pin provides the function of enable/disable of diagnostic functions, which can be used to obtain low power consumption if disabled. When multiple HD70402Q devices are used in one system, MCU can achieve sampling of CS voltage through one single ADC channel by connecting CS outputs of multiple HD70402Q devices together. This greatly reduces system cost.
●The HD70402Q supports the SSOP16PP and SSOP14PP packages.
