VND5E025AK-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 28 V CC Max on-state resistance (per ch.) R 25 m ON PowerSSO-24 Current limitation (typ) I 60 A LIMH (1) Reverse battery protected Off-state supply current I 2A S Electrostatic discharge protection 1. Typical value with all loads connected. Applications General All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Suitable as LED driver Very low standby current 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility The VND5E025AK-E is a double channel high- In compliance with the 2002/95/EC side driver manufactured in the ST proprietary european directive VIPower M0-5 technology and housed in the tiny Very low current sense leakage PowerSSO-24 package. The VND5E025AK-E is designed to drive 12 V automotive grounded Diagnostic functions loads delivering protection, diagnostics and an Proportional load current sense easy 3 V and 5 V CMOS compatible interface with High current sense precision for wide 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 Thermal shutdown indication output channel in order to provide enhanced 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 CC Load current limitation on-state and off-state open-load detection. The Self limiting of fast thermal transients current sensing and diagnostic feedback of the Protection against loss of ground and loss whole device can be disabled by pulling the of V CS DIS pin high to allow sharing of the external CC sense resistor with other similar devices.
