VND5T050AK-E STMicroelectronics

VND5T050AK-E Double channel high-side driver with analog current sense for 24 V automotive applications Datasheet production data Self limiting of fast thermal transients Protection against loss of ground and loss of V CC Thermal shutdown Electrostatic discharge protection PowerSSO-24 Application All types of resistive, inductive and capacitive Features loads Max transient supply voltage V 58 V CC Description Operating voltage range V 8 to 36V CC The VND5T050AK-E is a monolithic device made Typ On-State resistance (per ch.) R 50 m ON using STMicroelectronics VIPower technology, Current limitation (typ) I 34 A intended for driving resistive or inductive loads LIM with one side connected to ground. Active V CC Off state supply current I 2 A S pin voltage clamp protects the device against low energy spikes. General This device integrates an analog current sense Very low standby current which delivers a current proportional to the load 3.0 V CMOS compatible input current. Optimized electromagnetic emission Fault conditions such as overload, Very low electromagnetic susceptibility overtemperature or short to V are reported via CC Compliant with European directive the current sense pin. 2002/95/EC Output current limitation protects the device in Fault reset standby pin (FR Stby) overload condition. The device will latch off in Diagnostic Functions case of overload or thermal shutdown. Proportional load current sense The device is reset by a low level pass on the fault High current sense precision for wide range reset standby pin. currents A permanent low level on the inputs and fault Off-state open load detection reset standby pin disable all outputs and set the Output short to V detection CC device in standby mode. Overload and short to ground latch off Thermal shutdown latch-off Very low current sense leakage Protections Undervoltage shutdown Overvoltage clamp Load current limitation February 2016 DocID022694 Rev 4 1/33 This is information on a product in full production. www.st.comContents VND5T050AK-E Contents 1 Block diagram and pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2 Electrical specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.1 Absolute maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.2 Thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 2.3 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 2.4 Electrical characteristics curves . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 3 Application information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.1 GND protection network against reverse battery . . . . . . . . . . . . . . . . . . . 21 3.1.1 Solution 1: resistor in the ground line (RGND only) . . . . . . . . . . . . . . . . 21 3.1.2 Solution 2: diode (DGND) in the ground line . . . . . . . . . . . . . . . . . . . . . 22 3.2 Load dump protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 3.3 MCU I/Os protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 3.4 Maximum demagnetization energy (VCC = 24 V) . . . . . . . . . . . . . . . . . . 23 4 Package and PCB thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24 4.1 PowerSSO-24 thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24 5 Package and packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 5.1 PowerSSO-24 mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 5.2 PowerSSO-24 packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 6 Order codes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 31 7 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32 2/33 DocID022694 Rev 4
