1 / 55 page  October 2016 DocID027400 Rev 3 1/55 This is information on a product in full production. www.st.com VN7040AJ, VN7040AS High-side driver with MultiSense analog feedback for automotive applications Datasheet - production data Features Max transient supply voltage VCC 40 V Operating voltage range VCC 4 to 28 V Typ. on-state resistance (per Ch) RON 40 mΩ Current limitation (typ) ILIMH 34 A Standby current (max) ISTBY 0.5 µA • AEC-Q100 qualified • General − Single channel smart high-side driver with MultiSense analog feedback − Very low standby current − Compatible with 3 V and 5 V CMOS outputs • MultiSense diagnostic functions − Multiplexed analog feedback of: load current with high precision proportional current mirror, VCC supply voltage and TCHIP device temperature − Overload and short to ground (power limitation) indication − Thermal shutdown indication − OFF-state open-load detection − Output short to VCC detection − Sense enable/disable • Protections − Undervoltage shutdown − Overvoltage clamp − Load current limitation − Self limiting of fast thermal transients − Configurable latch-off on overtemperature or power limitation with dedicated fault reset pin − Loss of ground and loss of VCC − Reverse battery with external components − Electrostatic discharge protection Applications • All types of Automotive resistive, inductive and capacitive loads • Specially intended for Automotive Turn Indicators (up to P27W or SAE1156 and R5W paralleled or LED Rear Combinations) Description The devices are single channel high-side drivers manufactured using ST proprietary VIPower® M0- 7 technology and housed in PowerSSO-16 and SO-8 packages. The devices are designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, and to provide protection and diagnostics. The devices integrate advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown with configurable latch-off. A FaultRST pin unlatches the output in case of fault or disables the latch-off functionality. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions including high precision proportional load current sense, supply voltage feedback and chip temperature sense, in addition to the detection of overload and short circuit to ground, short to VCC and OFF-state open-load. A sense enable pin allows OFF-state diagnosis to be disabled during the module low-power mode as well as external sense resistor sharing among similar devices. |
