Description
The L9954LXP is a microcontroller driven
multifunctional door actuator driver for automotive
applications. Up to two DC motors and three
grounded resistive loads can be driven with three
half bridges and three high-side drivers. The
integrated standard Serial Peripheral Interface
(SPI) controls all operation modes (forward,
reverse, brake and high impedance). All
diagnostic information is available via SPI.
