VND5050AJ-E VND5050AK-E Double channel high side driver with analog current sense for automotive applications Features Max transient supply voltage V 41 V CC PowerSSO-12 PowerSSO-24 Operating voltage range V 4.5 to 36 V CC Max on-state resistance (per ch.) R 50 m ON Applications Current limitation (typ) I 18 A LIMH All types of resistive, inductive and capacitive (1) Off-state supply current I 2A S loads 1. Typical value with all loads connected Suitable as LED driver Main Inrush current active management by Description power limitation Very low standby current The VND5050AJ-E, VND5050AK-E is a 3.0 V CMOS compatible input monolithic device made using STMicroelectronics Optimized electromagnetic emission VIPower M0-5 technology. It is intended for driving resistive or inductive loads with one side Very low electromagnetic susceptibility connected to ground. Active V pin voltage CC In compliance with the 2002/95/ec clamp protects the device against low energy european directive spikes (see ISO7637 transient compatibility Diagnostic functions table). Proportional load current sense This device integrates an analog current sense High current sense precision for wide range which delivers a current proportional to the load currents current (according to a known ratio) when Current sense disable CS DIS is driven low or left open. When CS DIS Thermal shutdown indication is driven high, the current sense pin is in a high Very low current sense leakage impedance condition. Protections Output current limitation protects the device in Undervoltage shutdown overload condition. In case of long overload duration, the device limits the dissipated power to Overvoltage clamp safe level up to thermal shutdown intervention. Load current limitation Thermal shutdown with automatic restart allows Self limiting of fast thermal transients the device to recover normal operation as soon as Protection against loss of ground and loss fault condition disappears. of V CC Thermal shutdown Table 1.
