R 160 m ON Overtemperature shutdown with Current limitation (typ.) I 10 A LIMH autorestart (thermal shutdown) (1) Off-state supply current I 2 A S Reverse battery protected 1. Typical value with all loads connected. Electrostatic discharge protection General Application Inrush current active management by All types of resistive, inductive and capacitive power limitation loads Very low standby current Suitable as LED driver 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility Compliance with European directive The VND5E160ASO-E is a single channel high- 2002/95/EC side driver manufactured using ST proprietary VIPower M0-5 technology and housed in Very low current sense leakage SO-16L package. The device is designed to drive AEC-Q100 qualified 12 V automotive grounded loads, and to provide Diagnostic functions protection and diagnostics. It also implements a Proportional load current sense 3 V and 5 V CMOS-compatible interface for use High current sense precision for wide with any microcontroller. currents range The device integrates advanced protective Current sense disable functions such as load current limitation, inrush Off-state open-load detection and overload active management by power Output short to V detection CC limitation, overtemperature shut-off with auto- Overload and short to ground (power restart and overvoltage active clamp. A dedicated limitation) indication analog current sense pin is associated with every output channel providing enhanced diagnostic Thermal shutdown indication functions including fast detection of overload and Protections short-circuit to ground through power limitation Undervoltage shutdown indication, overtemperature indication, short- Overvoltage clamp circuit to V diagnosis and on-state and off-state CC Load current limitation open-load detection. The current sensing and Self limiting of fast thermal transients diagnostic feedback of the whole device can be disabled by pulling the CS DIS pin high to share Protection against loss of ground and loss the external sense resistor with similar devices. of V CC September 2013 Doc ID 022480 Rev 6 1/37 This is information on a product in full production. www.st.com 1Contents VND5E160ASO-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 25 3.4.1 Short to VCC and off-state open-load detection 26 3.5 Maximum demagnetization energy (VCC = 13.5 V) . 28 4 Package and PC board thermal data . 29 4.1 SO-16L 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 Doc ID 022480 Rev 6
