Avago Technologies announced two new miniature voltage/current threshold detection optocouplers for use in a wide range of industrial control applications Avago Technologies announced two new ...

while a feedback voltage of 4.5V results in a maximum duty cycle. The UCC2897A also provides a 5V reference, which you can use to bias the photo detector of the optocoupler through R6 in Figure 1.

These voltage/current sensing optocouplers are suitable for use in applications such as limit switch sensors, low voltage detectors, relay contact monitors, relay coil voltage monitors, and current ...

Meanwhile, output voltage regulation of ±8% is attainable without an optocoupler; when using an optocoupler, ±1.5% regulation is possible. A programmable volt-second clamp safeguards against ...
