VND5E025AS-E Double channel high-side driver with analog current sense for automotive applications Datasheet production data Features Max transient supply voltage V 41 V CC SO-16L Operating voltage range V 4.5 to 28 V CC 1( 5 Max on-state resistance (per ch.) R 25 m ON Current limitation (typ) I 60 A LIMH Overtemperature shutdown with auto (1) Off-state supply current I 2A S restart (thermal shutdown) 1. Typical value with all loads connected. Reverse battery protected Electrostatic discharge protection General Applications AEC-Q100 qualified 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 The VND5E025AS-E is a double 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 Diagnostic functions 12 V automotive grounded loads, and to provide Proportional load current sense protection and diagnostics. It also implements a 3 V and 5 V CMOS-compatible interface for the High current sense precision for wide use with any microcontroller. currents range Current sense disable The device integrates advanced protective Off-state open- load detection functions such as load current limitation, inrush 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 Thermal shutdown indication output channel providing enhanced diagnostic Protections functions including fast detection of overload and Undervoltage shutdown short-circuit to ground through power limitation indication, overtemperature indication, short- Overvoltage clamp circuit to V diagnosis and on-state and off-state Load current limitation CC open-load detection. The current sensing and Self limiting of fast thermal transients diagnostic feedback of the whole device can be Protection against loss of ground and loss disabled by pulling the CS DIS pin high to share of V CC the external sense resistor with similar devices.
