The L9951 and L9951XP are microcontroller driven, multifunctional rear door actuator drivers for automotive applications. Up to two DC motors and two grounded resistive loads can be driven with three half bridges and two hide side drivers.The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic information is available via the SPI.One half bridge for 7.4 A load (Ron= 150 m)Two half bridges for 5 A load (Ron= 200 m)Two highside drivers for 1.25 A load (Ron= 800 m)Programmable softstart function to drive loads with higher inrush currents (i.e.current > 7.4A, >5A, >1.25A)Very low current consumption in stand-by mode (IS< 3µA, typ. Tj= 85°C)All outputs short circuit protectedCurrent monitor output for all highside driversAll outputs over temperature protectedOpen load diagnostic for all outputsOverload diagnostic for all outputsProgrammable PWM control of all outputsCharge pump output for reverse polarity protection
