1 / 42 page  VNQ7050AJ Quad channel high-side driver with CurrentSense 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 50 mΩ Current limitation (typ) ILIMH 27 A Stand-by current (max) ISTBY 0.5 µA • Automotive qualified • General − Quad channel smart high-side driver with CS analog feedback − Very low standby current − Compatible with 3 V and 5 V CMOS outputs • CurrentSense diagnostic functions − Analog feedback of load current with high precision proportional current mirror − 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 Signal Lamps (up to P27W or SAE1156 or LED Rear Combinations) Description The device is a quad channel high-side driver manufactured using ST proprietary VIPower® M0-7 technology and housed in PowerSSO-16 package. The device is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing protection and diagnostics. The device integrates 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 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.
