Built-in analog current sense output delivers a current proportional to the load current. Device automatically turns off in case of ground pin disconnection. REVERSE BATTERY PROTECTION (**) ■ IN COMPLIANCE WITH THE 2002/95/EC EUROPEAN DIRECTIVE ■ t c u d o r DESCRIPTION The VND920-E is a double chip device made by using STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). P e t e l o s b O Table 2.
