Door actuator driver

Features

■

Three half bridges for 1.5A load (Ron=800mΩ)

■

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

■

Two highside drivers for 1.5A load (Ron=800mΩ)

■

Programmable softstart function to drive loads

with higher inrush currents (i.e. current >6A,

>1.5A)

■

Very low current consumption in standby mode

(IS < 6µA typ; Tj ≤ 85 °C)

■

All outputs short circuit protected

■

Current monitor output for highside OUT1,

OUT4, OUT5 and OUT6

■

All outputs over temperature protected

■

Open load diagnostic for all outputs

■

Overload diagnostic for all outputs

■

PWM control of all outputs

■

Charge pump output for reverse polarity

protection

Applications

■

Door actuator driver with bridges for mirror axis

control and highside driver for mirror defroster

and two 10W-light bulbs.

Description

The L9954 and L9954XP are microcontroller

driven, multifunctional door actuator drivers for

automotive applications. Up to two DC motors

and three grounded resistive loads can be driven

with three half bridges and three highside 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.
