VND5160AJ-E Double channel high side driver with analog current sense for automotive applications Features Max supply voltage V 41 V CC Operating voltage range V 4.5 to 36V CC PowerSSO-12 Max on-state resistance (per ch.) R 160 m ON Reverse battery protection (see Application Current limitation (typ) I 5 A LIMH schematic) (1) Off state supply current I 2 A S Electrostatic discharge protection 1. Typical value with all loads connected. Application General features All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Suitable as LED driver Very low stand-by current 3.0V CMOS compatible input Description Optimized electromagnetic emission Very low electromagnetic susceptibility The VND5160AJ-E is a monolithic device made using STMicroelectronics VIPower technology. It In compliance with the 2002/95/EC is intended for driving resistive or inductive loads European directive with one side connected to ground. Active V pin Diagnostic functions CC voltage clamp protects the device against low Proportional load current sense energy spikes (see ISO7637 transient High current sense precision for wide range compatibility table). This device integrates an currents analog current sense which delivers a current Current sense disable proportional to the load current (according to a Thermal shutdown indication known ratio) when CS DIS is driven low or left 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 restart allows the device to recover normal Protection against loss of ground and loss operation as soon as fault condition disappears. of V cc Thermal shut down Table 1.
