Hall inputs
High is defined as IN
+
> IN
–
, and low as the opposite.
An amplitude of 100 mV p-p (differential) or more is
desirable in the Hall signals. Connect capacitors between
the IN
+
and IN
–
pins if noise on the Hall signals causes
problems.

Output current detection
Connect a resistor between this pin and ground.
The output limitation maximum current, I
