Product Description

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 impedance). All diagnostic informations are available via SPI.
**Key Features**
One full bridge for 6A load (Ron=150 mΩ )
Two half bridges for 3A load (Ron=300 mΩ )
Two half bridges for 1.5A load (Ron=800 mΩ )
One highside driver for 6A load (Ron=100 mΩ )
Four highside drivers for 1.5 A load (Ron=800 mΩ )
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 μA typ; ICC <25 μA typ; Tj ≤ 85 °C)
All outputs short circuit protected
Current monitor output for 300 mΩ, 150 mΩ and 100 m highside drivers
All outputs over temperature protected
Open load diagnostic for all outputs
Overload diagnostic for all outputs
Seperated half bridges for door lock motor
PWM control of all outputs
Charge pump output for reverse polarity protection
