Datasheet File OCR Text:

The VN808 is the first octal single chip high-side driver developed in VIPower M0-3 technology. Both the control and power stage use N-MOS technology. VN808 has 8 different channels with single protection and diagnostic functions integrated on a single chip. The VN808 has been developed considering the needs of the industrial process control market.
High-power capability PowerSO-36; V cc /2 compatible inputs; Junction over-temperature protection; Case over-temperature protection for thermal independence of the channel; Current limitation; Shorted load protection; Under-voltage shutdown; Protection against loss of ground; Very low stand-by current; Compliance with 6100-4-4 IEC test up to 4.4kV.
The VN808 has built-in junction over-temperature protection which is thermally independent for each of the eight channels, it has a current limitation (1.1A typical), and a fast demagnetization block clamped at -52V typical. Thanks to the built-in protection each channel is self-protected against load short-circuiting and overloading. The device is able to manage large inductive loads, however care must be taken of the power dissipation related to the switching frequency in free-wheeling conditions. Both undervoltage protection and loss of ground protection with shutdown are added. For the very first time a case over-temperature protection is integrated into the VIPower switch. The typical RDS(on) of the VN808 is 150m per channel at 25C, while the operating voltage is inside the industrial range of 10.5V to 45V.

Double integrated thermal protection exists in VN808 in the form of: Junction temperature detection (TTSD) and protection, related to the single channel; Case temperature detection (TCSD) and protection, related to the whole device dissipation. The case temperature protection avoids PCB degradation if a large number of channels are overloaded. In fact the TCSD acts only on the overloaded channel; channels that are not overloaded continue to operate normally.
