protection

2 APPLICATIONS
Door Actuator Driver with bridges for door lock and
safe lock, mirror axis control, mirror fold and highside
driver for mirror defroster and four 5W-light bulbs.

3 DESCRIPTION
The L9950 is a microcontroller driven multifunctional door actuator driver for automotive applications.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 operation modes (forward, reverse, brake and high impedance).
All diagnostic informations are available via SPI
