General Features    CMOS COMPATIBLE INPUT    ON STATE OPEN LOAD DETECTION    OFF STATE OPEN LOAD DETECTION    SHORTED LOAD PROTECTION   UNDERVOLTAGE AND OVERVOLTAGE SHUTDOWN    PROTECTION AGAINST LOSS OF GROUND   VERY LOW STAND-BY CURRENT   REVERSE BATTERY PROTECTION (*)   IN COMPLIANCE WITH THE 2002/95/ECEUROPEAN DIRECTIVE DESCRIPTION The VN920DSP is a monolithic device made byusing STMicroelectronics VIPower M0-3Technology, intended for driving any kind of loadwith one side connected to ground.Active V CC  pin voltage clamp protects the deviceagainst low energy spikes (see ISO7637 transientcompatibility table). Figure 1. Package Active current limitation combined with thermalshutdown and automatic restart protect the deviceagainst overload. The device detects open load condition both is onand off state. Output shorted to V CC  is detected inthe off state. Device automatically turns off in caseof ground pin disconnection. Table 2.
