VN5010AK-E 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 36 V CC TM PowerSSO-24 Max on-state resistance R 10 m ON Reverse battery protection (see Figure 26) Current limitation (typ) I 65 A LIMH Electrostatic discharge protection Off-state supply current (typ) I 2A S Application Main features All types of resistive, inductive and capacitive Inrush current active management by power limitation loads Very low standby current 3.0v CMOS compatible input Description Optimized electromagnetic emission The VN5010AK-E is a monolithic device made Very low electromagnetic susceptibility using STMicroelectronics VIPower M0-5 In compliance with the 2002/95/EC technology. It is intended for driving resistive or European directive inductive loads with one side connected to Diagnostic functions ground. Active V pin voltage clamp protects the CC Proportional load current sense device against low energy spikes (see ISO7637 High current sense precision for wide range transient compatibility table). This device currents integrates an analog current sense which delivers Current sense disable a current proportional to the load current Thermal shutdown indication (according to a known ratio) when CS DIS is Very low current sense leakage driven low or left open. When CS DIS is driven high, the CURRENT SENSE pin is in a high Protections impedance condition. Output current limitation Undervoltage shutdown protects the device in overload condition. In case Overvoltage clamp of long overload duration, the device limits the Load current limitation dissipated power to safe level up to thermal Self limiting of fast thermal transients shutdown intervention. Thermal shutdown with Protection against loss of ground and loss automatic restart allows the device to recover of V CC normal operation as soon as fault condition Thermal shutdown disappears.
