Actuator detection

摘要

A voltage control circuit in an electronic device receives an actuator identification signal from a personality module of an actuator in the electronic device. The voltage control circuit determines, based on the actuator identification signal, an operating voltage for the actuator and providing a drive signal at the operating voltage to the actuator.
