VN5E160AS-E Single channel high side driver with analog for automotive applications Features Max supply voltage V 41 V CC Operating voltage range V 4.5 V to 28 V CC 62 Max ON-state resistance 1( 5 R 160 m ON (per ch.) Reverse battery protected Current limitation (typ) I 10 A LIMH Electrostatic discharge protection (1) OFF-state supply current I 2 A S Application 1. Typical value with all loads connected. All types of resistive, inductive and capacitive General loads Inrush current active management by Suitable as LED driver power limitation Very low standby current Description 3.0 V CMOS compatible inputs The VN5E160AS-E is a single-channel high-side Optimized electromagnetic emission driver manufactured in the ST proprietary Very low electromagnetic susceptibility VIPower M0-5 technology and housed in the In compliance with the 2002/95/EC tiny SO-8 package. The VN5E160AS-E is european directive designed to drive 12 V automotive grounded Very low current sense leakage loads delivering protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any Diagnostic functions microcontroller. Proportional load current sense The device integrates advanced protective High-precision current sense for functions such as load current limitation, inrush wide-range currents and overload active management by power Current sense disable limitation, overtemperature shut-off with OFF-state open-load detection auto-restart and overvoltage active clamp. A Output short to V detection CC dedicated analog current sense pin is associated Overload and short to ground with every output channel in order to provide (power limitation) indication ehnanced diagnostic functions including fast detection of overload and short-circuit to ground Protections through power limitation indication, Undervoltage shutdown overtemperature indication, short-circuit to V CC Overvoltage clamp diagnosis and ON & OFF state open-load Load current limitation detection. The current sensing and diagnostic Self-limiting of fast thermal transients 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 the external sense resistor with other similar CC devices.
