1 / 43 page  VND7140AJ12 Double 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 V to 28 V Minimum cranking supply voltage (VCC decreasing) VUSD_Cranking 2.85 V Typ. on-state resistance (per Ch) RON 140 mΩ Current limitation (typ) ILIMH 12 A Standby current (max) ISTBY 0.5 µA • Automotive qualified • Extreme low voltage operation for deep cold cranking applications (compliant with LV124, revision 2013) • General − Double channel smart high-side driver with CurrentSense analog feedback − Very low standby current − Compatible with 3 V and 5 V CMOS outputs • CurrentSense diagnostic functions − Multiplexed 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 − 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 R10W or LED Rear Combinations) Description The device is a double channel high-side driver manufactured using ST proprietary VIPower® technology and housed in PowerSSO-12 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. A current sense delivers high precision proportional load current 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.
