Hi forum.
I need to drive a small solenoid valve that operates at 24VDC 10W in a continuous selectable frequency range from 1 to 250Hz PWM frequency with a selectable duty cycle from 2-100%.
PWM frequency is relatively low, but I need to vary it together with the duty cycle.
I explain: Duty Cycle controls the percentage of time that the valve is ON within a given cycle period: consider for example 150 Hz (cycles/second). (1) At a 50% duty cycle, the valve will be ON for 3.3 msec and will be OFF for 3.3 msec. I need to control this accurately.
Is there an IC that maybe has multiple outputs like the DRV110?
Any help appreciated,
best regards
