description
The IC is developed for automotive applications and can also
ÿ 8 high current outputs
be used in several other application areas. The IC is well suited
(RON typ. 1.5 Ý / Imax=350mA)
ÿ Wide output operating voltage range
to drive relays, lamps, bus systems etc. with medium power
consumption.

ÿ Output open- and short - circuit detection
The device provides a serial data bus for comunication with a µC
ÿ Individual output short - circuit protection
and 8 identical power drivers. All outputs are short circuit pro-
ÿ Thermal overload protection
tected. A thermal shut-off protects the device against thermal
ÿ – 40°C to + 125°C operating temperature
overload. Readback capability enables fault detection as well as
ÿ SO20w package or QFN 5x5 20Ld package
simple switch monitoring.
