  • Circuits and methods for controlling PWM input of driver circuit
    Patent number: 8638080
    Abstract: Circuits and methods for controlling Pulse Width Modulation (PWM) input of a driver circuit during transition of states are provided. The driver circuit is operative in one of a high state, a low state and a tri-state based on the PWM input. The method includes receiving a tri-state command for transition from the high state to the tri-state. A PWM output signal is enabled to transition from a high logic value to a low logic value for driving the driver circuit from the high state to the low state upon receipt of the tri-state command. The PWM output signal is enabled to transition from the low logic value to a tri-state logic value for driving the driver circuit from the low state to the tri-state upon elapse of a threshold time delay. The PWM input to the driver circuit is based on the PWM output signal.
