FOperation notes
(1)
The power save input is an I / O circuit like the own
shown in Fig.1.
The thermal derating characteristics of the power save
pin is –8mV / _C, and the resistance will fluctuate be-
tween 30% so be careful of the input voltage range.
(2)
The input circuit shown in Fig.4 is used for the Hall inputs.
The Hall elements can be connected either in series or
in parallel.
