Door actuator driver

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 m

Ω, 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

Applications

■ Door actuator driver with bridges for door lock

and safe lock, mirror axis control, mirror fold

and highside driver for mirror defroster and four

10W-light bulbs.

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.
