L9950XP Door actuator driver

The L9950 and L9950XP are microcontroller driven multifunctional door actuator driver for automotive applications.Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five highside drivers. The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedan.

Features

■ One full bridge for 6A load (Ron=150 m )
■ Two half bridges for 3A load (Ron=300 m )
■ Two half bridges for 1.5A load (Ron=800 m )
■ One highside driver for 6A load (Ron=100 m )
■ Four highside drivers for 1.5 A load (Ron=800 m )
■ Programmable softstart function to drive loads with higher inrush currents (i.e. current >6 A,>3 A,>1.5 A)
■ Very low current consumption in standby mode (IS < 6 A typ; ICC <25 A typ; Tj 85 °C)
■ All outputs short circuit protected
■ Current monitor output for 300 m, 150 m and 100 m highside drivers
■ All outputs over temperature protected
■ Open load d.
