ORDERING NUMBER:
tended for automotive applications realized in
multipower BCD60II technology. Up to three DC
motors and one grounded resistive load can be
driven with its four half-bridge and one high-side
driverpower outputs. The microcomputer compatible bidirectional parallel bus allows several interfaces connected on the same bus (multiplex system). The full diagnosticinformation is available on
thebus.
