VN5E016AFH-E 16 m high-side driver with analog current sense for automotive applications Features HPak Max supply voltage V 41V CC Operating voltage range V 4.5 to 28V CC Max on-state resistance (per ch.) R 16 m Reverse battery protected ON Electrostatic discharge protection Current limitation (typ) I 73 A LIMH (1) Off-state supply current I 2 A S Applications 1. Typical value with all loads connected. All types of resistive, inductive and capacitive loads General Suitable as LED driver Inrush current active management by power limitation Very low standby current Description 3.0 V CMOS compatible inputs The VN5E016AFH-E is a single channel high-side Optimized electromagnetic emissions driver manufactured using ST proprietary Very low electromagnetic susceptibility VIPower M0-5 technology and housed in HPak In compliance with the 2002/95/EC package. The device is designed to drive 12 V European directive automotive grounded loads, and delivering protection and diagnostics. It also implements 3 V Diagnostic functions and 5 V CMOS compatible interface for use with Proportional load current sense any microcontroller. High current sense precision for wide The device integrates advanced protective current range functions such as load current limitation, inrush Current sense disable and overload active management by power Off-state open-load detection limitation, overtemperature shut-off with auto Output short to V indication CC restart and overvoltage active clamp. Overload and short to ground (power A dedicated analog current sense pin is limitation) indication associated with every output channel providing Thermal shutdown indication enhanced diagnostic functions. These functions Protections include fast detection of overload and short-circuit Undervoltage shutdown to ground through power limitation indication, overtemperature indication, short-circuit to V Overvoltage clamp CC diagnosis and ON-state and OFF-state open-load Load current limitation detection. Self limiting of fast thermal transients The current sensing and diagnostic feedback of Protection against loss of ground and loss the whole device can be disabled by pulling the of V CC CS DIS pin high to share external sense resistor Overtemperature shutdown with auto with similar devices. restart (thermal shutdown) September 2013 Doc ID 18043 Rev 2 1/37 www.st.com 1Contents VN5E016AFH-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 Waveforms 18 2.5 Electrical characteristics curves 21 3 Application information . 24 3.1 GND protection network against reverse battery . 24 3.1.1 Solution 1: resistor in the ground line (RGND only) 24 3.1.2 Solution 2: a diode (DGND) in the ground line . 25 3.2 Load dump protection 25 3.3 MCU I/Os protection . 25 3.4 Current sense and diagnostic 26 3.4.1 Short to VCC and OFF-state open-load detection . 27 3.5 Maximum demagnetization energy (VCC = 13.5V) . 28 4 Package and PC board thermal data . 29 4.1 HPak thermal data 29 5 Package and packing information . 32 5.1 ECOPACK . 32 5.2 HPak mechanical data . 32 5.3 Packing information . 34 6 Order codes . 35 7 Revision history . 36 2/37 Doc ID 18043 Rev 2
