Method of forming a semiconductor device and structure therefor
In one embodiment, a control circuit for a linear vibration motor may be configured to drive the linear vibration motor to vibrate using a closed loop run mode or an open loop run mode, and may be configured to control the linear vibration motor to stop vibrating using an anti-drive signal wherein the frequency is adjusted to be near to an estimated value of the natural frequency of the linear vibration motor.
