[2] Since the output 2 of the AN8017SA is assuming the bipolar transistor driving, it is necessary to pay attention to
the following points when an n-channel MOSFET is driven directly.
1. Select an n-channel MOSFET having a low input
capacitance
The AN8017SA is of the constant current (50 mA
maximum) output source current type circuit assum-
ing the bipolar transistor driving. Also, its sink cur-
rent capability is around 80 mA maximum. For those
reason, it is necessary to pay attention to the increase
of loss due to the extension of the output rise time and
the output fall time.
If any problem arises, there is a method to solve it
by amplifying with inverters as shown in figure 1.
