    Abstract: Disclosed examples include methods and circuits to drive a haptic actuator, in which a single input signal from a host device has a first state representing a command to drive the actuator and a second state representing a command to stop the actuator. A control circuit provides a drive control signal to a driver circuit to drive the haptic actuator in response to the control signal transitioning to the first state, and to stop the haptic actuator in response to the control signal transitioning to the second state. A timer circuit places the circuit in a low power mode a predetermined time after the control signal transitions to the second state, or the control circuit places the circuit in the low power mode in response to a feedback signal indicating that the actuator has reached a stopped condition.

    Abstract translation: 公开的示例包括用于驱动触觉致动器的方法和电路，其中来自主机设备的单个输入信号具有表示驱动致动器的命令的第一状态和表示停止致动器的命令的第二状态。 控制电路向驱动电路提供驱动控制信号，以响应于控制信号转变到第一状态来驱动触觉致动器，并且响应于控制信号转变到第二状态来停止触觉致动器。 定时器电路在控制信号转变到第二状态之后的预定时间内将电路置于低功率模式，或者控制电路响应于指示致动器已经达到停止的反馈信号而将电路置于低功率模式 条件。
