VN7010AJ High-side driver with MultiSense analog feedback for automotive applications Datasheet - production data Loss of ground and loss of V CC Reverse battery with external components Electrostatic discharge protection Applications All types of Automotive resistive, inductive Features and capacitive loads Max transient supply voltage V 40 V CC Specially intended for Automotive Headlamps Operating voltage range VCC 4 to 28 V Typ. on-state resistance (per Ch) R 10 m ON Description Current limitation (typ) ILIMH 91 A The device is a single channel high-side driver Standby current (max) I 0.5 A STBY manufactured using ST proprietary VIPower M0- 7 technology and housed in PowerSSO-16 package. The device is designed to drive 12 V Automotive qualified automotive grounded loads through a 3 V and General 5 V CMOS-compatible interface, providing Single channel smart high-side driver protection and diagnostics. with MultiSense analog feedback The device integrates advanced protective Very low standby current functions such as load current limitation, overload Compatible with 3 V and 5 V CMOS active management by power limitation and outputs overtemperature shutdown with configurable MultiSense diagnostic functions latch-off. Multiplexed analog feedback of: load current with high precision proportional A FaultRST pin unlatches the output in case of current mirror, V supply voltage and CC fault or disables the latch-off functionality. TCHIP device temperature Overload and short to ground (power A dedicated multifunction multiplexed analog limitation) indication output pin delivers sophisticated diagnostic Thermal shutdown indication functions including high precision proportional OFF-state open-load detection load current sense, supply voltage feedback and Output short to VCC detection chip temperature sense, in addition to the Sense enable/disable detection of overload and short circuit to ground, Protections short to V and OFF-state open-load. CC Undervoltage shutdown A sense enable pin allows OFF-state diagnosis to Overvoltage clamp be disabled during the module low-power mode Load current limitation as well as external sense resistor sharing among Self limiting of fast thermal transients similar devices. Configurable latch-off on overtemperature or power limitation with dedicated fault reset pin May 2015 DocID027394 Rev 1 1/45 www.st.com This is information on a product in full production.
