Operating Description
Input Schmitt Triggers
circuits to prevent the NCP5008/NCP5009 against
uncontrolled operation. The typical dynamic characteristics
of the related pins are depicted in Figure 18.

the output current is derived by equation I
internal constant k being equal to 746.
ESD Protection
protect the pins against the ESD spikes voltages. To cope
with the different ESD voltages developed in the
applications, the built−in structures have been designed to
handle $2.0 kV in Human Body Model (HBM) and
$200 V in Machine Model (MM) and on each pin.
