The L9950 is a microcontroller driven multifunc-
tional door actuator driver for automotive applica-
tions.Up to five DC motors and five grounded
resistive loads can be driven with six half bridges
and five highside drivers. The integrated standard
serial peripheral interface (SPI) controls all opera-
tion modes (forward, reverse, brake and high im-
pedance).
All diagnostic informations are available via SPI.
