Door Actuator Driver 36-Pin PowerSO T/R

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.

One full bridge for 6A load (Ron=150 mO )

Two half bridges for 3A load (Ron=300 mO )

Two half bridges for 1.5A load (Ron=800 mO )

One highside driver for 6A load (Ron=100 mO )

Four highside drivers for 1.5 A load (Ron=800 mO )

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="">

All outputs short circuit protected

Current monitor output for 300 mO, 150 mO 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
