Working Principles

The MAX690EPA+G002 is a monolithic CMOS circuit that utilizes an internal oscillator to generate precise timing signals. The timer duration is determined by an external resistor and capacitor connected to the CT pin. When the timer is enabled, the internal oscillator starts counting, and when the count reaches the preset value, the timer output changes state. The trigger input can be used to start or restart the timer, while the reset input allows manual or external control over the timer operation.
