DESCRIPTION
The IC is an 8 channel parallel power driver circuit (low side) with
microcontroller compatible bidirectional dataports and output
status monitoring.
This IC is designed for driving and controlling medium loads such
as relays, lamps, LED, bus systems or other. It has got a bidirec-
tional 8 bit-data bus and 8 identical power outputs.
With its readback capability the status of the load can be deter-
mined. That makes easy diagnosis possible and lets the designer
even control simple switches.
Two versions are available: 910.32 in standard CMOS technology
and 910.13 in SOI technology, which has high immunity against
substrate currents.
