#116391 - Cause or effect? Responding to: ???'s previous message |
Do you specifically need to detect that the supplies have shorted to earth, or just detect that the voltage has fallen below an acceptable level?
How do you distinguish a short to earth from some other overload? Does it matter? Vinita Dhamele said:
we have very little idea of how to ... transform the voltage level to ttl. How about a simple potential divider? and a comparator? |
