Abstract:
An apparatus, such as a haptic-enabled device, and a method for providing boost protection logic are presented. The method comprises receiving, by a control circuit of the apparatus, a nonzero drive signal to be used by the haptic actuator to generate a haptic effect. The control circuit causes a first portion of the nonzero drive signal to be applied to the haptic actuator in a boost mode. The control circuit detects a boost duration exceeding a first defined time threshold, such as a boost timeout threshold, or detects an accumulated boost time exceeding the first defined time threshold. In response, the control circuit causes a second portion of the nonzero drive signal to be applied to the haptic actuator in an amplitude-limited mode.
