General 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.
The device provides a serial data bus for comunication with a µC and 8 identical power drivers. All outputs are short circuit protected. A thermal shut-off protects the device against thermal overload. Readback capability enables fault detection as well as simple switch monitoring.
