L9953XP
Door actuator driver
Features
One full bridge for 6A load (Ron=150mΩ)
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 stand-by
mode (IS < 6µA typ; Tj 85 °C)
All outputs short circuit protected
Current monitor output for highside OUT1,
OUT4, OUT5 and OUT8
All outputs over temperature protected
Open load diagnostic for all outputs
Overload diagnostic for all outputs
Separated half bridges for door lock motor
PWM control of all outputs
Charge pump output for reverse polarity
protection
PowerSO-36
PowerSSO-36
Applications
Door actuator driver with bridges for door lock ,
mirror axis control, mirror fold and highside
driver for mirror defroster and two 10W-light
bulbs.
Description
The L9953 and L9953XP are microcontroller
driven multifunctional door actuator driver for
automotive applications. Up to three DC motors
and three grounded resistive loads can be driven
with five 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 informations are available via SPI.
