The ML610Q101/102 have a single output PWM modules on chip. This function generates a pulse width modulated output, which would typically be used to modulate drivers of analog electronics. A PWM signal can be used to control analog components with a high level of control. A PWM signal allows an analog integrating circuit, which is a circuit that averages the input signal over time to be controlled by a digital signal that appears to the analog component as an analog signal. This is done by relatively quickly pulsing the power to a device on and off. The quick pulsing is referred to as modulating. The integrating nature of the load averages the modulated signal so that it appears as a continuous constant analog signal. As the modulation period or duty cycle increases or decreases the effective analog voltage increases and decreases proportionally. The PWM module in the ML610Q101/102 have a single output that can be routed to one of three pins, for maximum flexibility in PCB layout. The period of the PWM can range from 122nS to 2 seconds depending upon the reference clock. The duty cycle has 16-bit resolution. The graphs above show in a general way the effect of changing the period, or duty cycle, of the PWM output. The advantage of this module is that both characteristics can be modified depending upon the needs of the system. As is shown from the block diagram of the PWM module, there are wide arrays of features, including emergency stop that allow the designer to control the analog components of the system.
