High End Driver and Passenger Door
The actuator drivers designed by ST for automotive door zone applications are characterized by a scalable actuator driving concept, compatible with package and software, to satisfy the multiplicity of door electronics variants today. The drivers support all regular door zone loads such as door lock motors, mirror folder and leveling, defroster, and several lighting functions from LEDs to incandescent bulbs.
L9952 is a sophisticated power management device, enabling the application to achieve a very low quiescent current. Control and diagnostics for all devices are managed via a serial peripheral interface (SPI). They are available in small power packages, offering superior thermal performance – ideal for compact and lightweight systems. The combination of L9950 and L9952 offers an advanced system solution for high-end front door modules. Power management features are covered by the L9952, whereas L9950 is capable of driving a comprehensive actuator arrangement
