Typical value with all loads connected General features Application Inrush current active management by All types of resistive, inductive and capacitive power limitation loads Very low stand-by current 3.0 V CMOS compatible input Description Optimized electromagnetic emission Very low electromagnetic susceptibility The VN5012AK-E is a monolithic device made In compliance with the 2002/95/EC using STMicroelectronics VIPower M0-5 european directive technology. It is intended for driving resistive or 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 driven low or left open. When CS DIS is driven Very low current sense leakage 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 shutdown intervention. Thermal shutdown with Self limiting of fast thermal transients automatic restart allows the device to recover Protection against loss of ground and loss normal operation as soon as fault condition of V CC disappears.
