STMicroelectronics has designed a group of actuator drivers to address all automotive door-zone applications for the multiplicity of door-electronics variants today. They are characterized by a scalable-actuator driving concept compatible with package and software.
The drivers support all regular door-zone loads such as door-lock motors, mirror folders and leveling, defroster and lighting functions from LEDs to incandescent bulbs.
The power-management system device enables applications to achieve a very low quiescent current. Control and diagnostics for all devices are managed via a serial peripheral interface (SPI).
ST’s actuator drivers are available in small power packages, offering superior thermal performance – ideal for compact and lightweight systems.
The car-body door actuator family housed in the same packages (PowerSO-36 and PowerSSO-36) is pin-to-pin compatible, therefore targeting different market segments.
This provides a real family approach since project designers can consider one option or another, without any further change on the board.
