VND5025AK-E Double channel high side driver with analog current sense for automotive applications Features Max transient supply voltage V 41V CC Operating voltage range V 4.5 to 36V CC PowerSSO-24 Max on-state resistance (per ch.) R 25 m ON Electrostatic discharge protection Current limitation (typ) I 41 A LIMH (1) Off-state supply current I 2 A S Application 1. Typical value with all loads connected. All types of resistive, inductive and capacitive loads Main Suitable as LED driver In-rush current active management by power limitation Very low standby current Description 3.0V CMOS compatible input The VND5025AK-E is a monolithic device made Optimized electromagnetic emission using STMicroelectronics VIPower M0-5 Very low electromagnetic susceptibility technology, intended for driving resistive or In compliance with the 2002/95/EC inductive loads with one side connected to European directive ground, and suitable for driving LEDs. Active V Package: ECOPACK CC pin voltage clamp protects the device against low Diagnostic functionsDoc ID 12581 energy spikes (see ISO7637 transient Proportional load current sense compatibility table). This device integrates an High current sense precision for wide range analog current sense which delivers a current currents proportional to the load current (according to a Current sense disable known ratio) when CS DIS is driven low or left Thermal shutdown indication open. When CS DIS is driven high, the Very low current sense leakage CURRENT SENSE pin is in a high impedance Protection condition. Output current limitation protects the Undervoltage shut-down device in overload condition. In case of long Overvoltage clamp overload duration, the device limits the dissipated Load current limitation power to safe level up to thermal shut-down Self-limiting of fast thermal transients intervention. Thermal shut-down with automatic Protection against loss of ground and loss restart allows the device to recover normal of V CC operation as soon as fault condition disappears.
