L9953LXP
Door actuator driver
Features
■ Three half bridges for 0.75A loads
(R_DSon=1600mΩ)
■ Two configurable high side driver for up to 1.5A
load (R_DSon=500mΩ) or 0.35A load
(R_on=1800mΩ)
■ One full bridge for 6A load (R_on=150mΩ)
■ One highside driver for 6A load (R_on=100mΩ)
■ Programmable soft start function to drive loads
with higher inrush currents (i.e. current >6A,
>1.5A)
■ Very low current consumption in standby mode
(I_S < 6µA typ; T_j ≤ 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
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 and/or LEDs.
Description
The L9953LXP is a 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.
