The device provides a serial data bus for comunication with a µC
and
8
identical power drivers. All outputs are short circuit pro-
tected. A thermal shut-off protects the device against thermal
overload. Readback capability enables fault detection as well as
simple switch monitoring.
DESCRIPTION
The IC is developed for automotive applications and can also
be used in several other application areas. The IC is well suited
to drive relays, lamps, bus systems etc. with medium power
consumption.
