Hall effect


Posted on Feb 5, 2014

A series resistor, and a bypass capacitor along with a zener in parallel with the hall sensor to clamp transients that still get through. I use hall sensors here at work on a daily basis. After 15 years of working with them, I know that they`re generally robust, but do fail under certain conditions and I`m well versed in what they are. Want to see the inside of a failed sensor Look here.

This circuit works fine but I have yet to run more than a few minutes before the Hall effect goes T*ts up and dies. I have put protection diode and capacitor as recommended elsewhere but no luck. Any ideas By the way Creast, what hall sensor are you using Can you give us the part number If not, verify you have the correct pin out. Generally they are as follows: I can`t help but wonder if you have output and power pins reversed. The hall will actually sort of work that way, but it shorts out the power supply through itself every time it turns on. Luc, He did give his circuit diagram. It`s in his original post. And, bipolar, non-latching, hall sensors are "you`ve seen one, you`ve seen them all". My suggestions were for general filtering, bypassing, and transient protection. If you`d draw out my recommendations, you`d see that it is not wrong.

Designing robot is a part of my hobby, I teach robotic engineering as a job. As far as the diagram is...
