DESCRIPTION
The L9947 is a bus controlled power interface in-
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
driver power outputs. The microcomputer compat-
ible bidirectional parallel bus allows several inter-
faces connected on the same bus (multiplex sys-
tem). The full diagnosticinformation is available on
thebus.
