R 160 m ON Overtemperature shutdown with Current limitation (typ) I 10 A LIMH autorestart (thermal shutdown) (1) Reverse battery protected Off-state supply current I 2 A S Electrostatic discharge protection 1. Typical value with all loads connected. Application General 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 Description Optimized electromagnetic emission Very low electromagnetic susceptibility The VN5E160ASO-E is a single channel high- Compliant with European directive side driver manufactured using ST proprietary 2002/95/EC VIPower M0-5 technology and housed in Very low current sense leakage SO-16L package. The device is designed to drive 12 V automotive grounded loads, and to provide AEC-Q100 qualified protection and diagnostics. It also implements a Diagnostic functions 3 V and 5 V CMOS-compatible interface for the Proportional load current sense use with any microcontroller. High-precision current sense for The device integrates advanced protective wide-range currents 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 Output short to V detection CC auto-restart and overvoltage active clamp. A Overload and short to ground dedicated analog current sense pin is associated (power limitation) indication with every output channel providing ehnanced diagnostic functions including fast detection of Protections overload and short-circuit to ground through Undervoltage shutdown power limitation indication, overtemperature Overvoltage clamp indication, short-circuit to V diagnosis and ON- CC Load current limitation state and off-state open-load detection. The Self-limiting of fast thermal transients current sensing and diagnostic feedback of the whole device can be disabled by pulling the Protection against loss of ground and loss CS DIS pin high to share the external sense of V CC resistor with similar devices.
