VND5E160AJ-E Double channel high side driver with analog current sense for automotive applications Features Max transient supply voltage V 41 V CC Operating voltage range V 4.5 to 28V CC PowerSSO-12 Max On-state resistance (per ch.) R 160 m ON Reverse battery protected (see Application Current limitation (typ.) I 10 A LIMH schematic) (1) Off state supply current I 2 A S Electrostatic discharge protection 1. Typical value with all loads connected. Application General All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Suitable as LED driver Very low stand-by current 3.0 V CMOS compatible inputs Description Optimized electromagnetic emissions Very low electromagnetic susceptibility The VND5E160AJ-E is a single channel high-side In compliance with the 2002/95/EC driver manufactured in the ST proprietary european directive VIPower M0-5 technology and housed in the tiny PowerSSO-12 package. The VND5E160AJ-E is Very low current sense leakage designed to drive 12V automotive grounded loads Diagnostic functions delivering protection, diagnostics and easy 3V Proportional load current sense and 5V CMOS compatible interface with any High current sense precision for wide microcontroller. currents range The device integrates advanced protective Current sense disable functions such as load current limitation, inrush Off state openload detection and overload active management by power Output short to V detection CC limitation, over-temperature shut-off with Overload and short to ground (power auto-restart and over-voltage active clamp. A limitation) indication dedicated analog current sense pin is associated Thermal shutdown indication with every output channel in order to provide Ehnanced diagnostic functions including fast Protections detection of overload and short-circuit to ground Undervoltage shutdown through power limitation indication, over- Overvoltage clamp temperature indication, short-circuit to Vcc Load current limitation diagnosis and ON & OFF state open load Self limiting of fast thermal transients detection. The current sensing and diagnostic feedback of the whole device can be disabled by Protection against loss of ground and loss pulling the CS DIS pin high to allow sharing of of V CC the external sense resistor with other similar Over-temperature shutdown with devices. autorestart (thermal shutdown) September 2013 Rev 3 1/37 www.st.com 37Contents VND5E160AJ-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 : 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 PowerSSO-12 thermal data . 29 5 Package and packing information . 32 5.1 ECOPACK packages . 32 5.2 Package mechanical data 32 5.3 Packing information . 34 6 Order codes . 35 7 Revision history . 36 2/37
