L9947 Produktdetails

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.


■ LOW CONSUMPTION IN STANDBY MODE
   (<100µA AT ROM TEMP; < 150µA AT 130°C)
■ TWO HALF BRIDGES FOR 3A LOAD
   (RDSON = 0.25Ω TYP; Tj = 25°C)
■ TWO HALF BRIDGES FOR 0.5A LOAD
   (RDSON = 2.5Ω TYP; Tj = 25°C)
■ HIGH SIDE DRIVER FOR 2.5A LOAD
   (RDSON = 0.45Ω TYP; Tj = 25°C)
■ DIRECT CONTROLLED BY µC (MULTIPLEX SYSTEM)
■ OUTPUT HIGH/LOW LEVEL DIAGNOSTIC
■ OVERCURRENT SWITCH OFF AND DIAGNOSTIC
■ OVERTEMPERATURE DIAGNOSTIC BEFORE SWITCH OFF
■ OPEN LOAD DIAGNOSTIC
