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.
