Output block power supply and output current
detection
Connect low-resistance resistors Rf between
these pins and VCC.
The output current is limited to the current
value set by IOUT = VREF/Rf.

Hall device inputs
These inputs return a high level when IN+ >
IN- and a low level when IN– > IN+.
A Hall signal amplitude of at least 100 mV p-p
(differential) is desirable. Insert a capacitor
between IN+ and IN- if noise on the Hall signal
is a problem.

capacitor and a resistor.
