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.
