VN7040AS-E, VN7040AJ-E High-side driver with MultiSense analog feedback for automotive application Datasheet - production data Configurable latch-off on overtemperature or power limitation with dedicated fault reset pin Loss of ground and loss of V CC 62 Reverse battery with external components Electrostatic discharge protection Features Applications Max transient supply voltage V 40 V CC All types of automotive resistive, inductive and Operating voltage range V 4 to 28 V CC capacitive loads Typ. on-state resistance (per Ch) R 40 m ON Specially intended for Automotive Turn Indicators (up to P27W or SAE1156 and R5W Current limitation (typ) I 34 A LIMH paralleled or LED Rear Combinations) Stand-by current (max) I 0.5 A STBY Description General The VN7040AS-E and VN7040AJ-E are single Single channel smart high-side driver with channel high-side drivers manufactured using ST MultiSense analog feedback proprietary VIPower technology and housed in Very low standby current PowerSSO-16 and SO-8 packages. The devices Compatible with 3 V and 5 V CMOS are designed to drive 12 V automotive grounded outputs loads through a 3 V and 5 V CMOS compatible interface, and to provide protection and MultiSense diagnostic functions diagnostics. Multiplexed analog feedback of: load current with high precision proportional The devices integrate advanced protective current mirror, V supply voltage and functions such as load current limitation, overload CC T device temperature active management by power limitation and CHIP overtemperature shutdown with configurable Overload and short to ground (power latch-off. A FaultRST pin unlatches the output in limitation) indication case of fault or disables the latch-off functionality. Thermal shutdown indication OFF-state open-load detection A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic Output short to V detection CC functions including high precision proportional Sense enable/ disable load current sense, supply voltage feedback and Protections chip temperature sense, in addition to the Undervoltage shutdown detection of overload and short circuit to ground, Overvoltage clamp short to V and OFF-state open-load. CC Load current limitation A sense enable pin allows OFF-state diagnosis to Self limiting of fast thermal transients be disabled during the module low-power mode as well as external sense resistor sharing among similar devices.
