Single Hall Effect Switch
A grade
B grade
-Operating principle
ATS137 is a three pins Hall Effect switch IC which can turn magnetic flux variety to digital output signal. In
other words, it is an interface from magnetic system to electrical one by Hall effect. The illustrations are shown
in Fig.1.
Output driver is open-collector topology and maximum sink current (I
shown as Fig.2.
