Description
The L9947 is a bus controlled power interface intended 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 compatible bidirectional parallel bus allows several interfaces connected on the same bus (multiplex system). The full diagnostic information is available on the bus.
