VN7020AJ-E High-side driver with MultiSense analog feedback for automotive application Datasheet - production data Loss of ground and loss of V CC Configurable latch-off on overtemperature or power limitation with dedicated fault reset pin PowerSSO-16 GAPGCFT00327 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 capacitive loads Operating voltage range V 4 to 28 V CC Specially intended for Automotive Turn Typ. on-state resistance R 20 m ON Indicators (up to 2 x P27W or SAE1156 and Current limitation (typ) I 63 A LIMH R5W paralleled or LED Rear Combinations) Stand-by current (max) I 0.5 A STBY Description General The VN7020AJ-E is a single channel high-side Automotive qualified driver manufactured using ST proprietary Single channel smart high-side driver with VIPower technology and housed in MultiSense analog feedback PowerSSO-16 package. The device is designed to drive 12 V automotive grounded loads through Very low standby current a 3 V and 5 V CMOS-compatible interface, and to Compatible with 3 V and 5 V CMOS provide protection and diagnostics. outputs The device integrates advanced protective MultiSense diagnostic functions functions such as load current limitation, overload Multiplexed analog feedback of: load active management by power limitation and current with high precision proportional overtemperature shutdown with configurable current mirror, V supply voltage and CC latch-off. A FaultRST pin unlatches the output in T device temperature CHIP case of fault or disables the latch-off functionality. Overload and short to ground (power limitation) indication A dedicated multifunction multiplexed analog 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 V detection CC 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 similar devices.
