	■ CMOS-compatible input					SO-16L
	■ Proportional load current sense
	■	Shorted load protection				Description
	■ Under-voltage and over-voltage shutdown					The VND600 is a double chip device designed in
		Over-voltage clamp
	■					STMicroelectronics VIPower M0-3 technology.
	■	Thermal shutdown				The VND600 is intended for driving any type of
	■	Current limitation				load with one side connected to ground. The
						active VCC pin voltage clamp protects the device
	■ Protection against loss of ground and loss of
						against low energy spikes (see ISO7637 transient
		VCC				compatibility table). Active current limitation
	■ Very low standby power dissipation					combined with thermal shutdown and automatic
	■ Reverse battery protected (see Application					restart protects the device against over-load.
		schematic )				The device integrates an analog current sense
						output which delivers a current proportional to the

load current. The device automatically turns off in the case where the ground pin becomes disconnected.

2.1Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to Absolute maximum rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics sure program and other relevant quality document.
