______________________________________________________________________________________
Figure 1 shows the detailed logic operation of the hot-
swap enable signals Chx_EN1, Chx_EN2, and ON_, as
well as the effect of various fault conditions.
An input undervoltage threshold control for enabling the
hot-swap channel can be implemented by placing a
resistive divider between the drain of the hot-swap FET
and ground, with the midpoint connected to ON_. The
turn-on threshold voltage for the channel is then:
VEN = 0.6V x (R1 + R2)/R2
The maximum rating for the ON_ pin is 6V; do not
exceed this value.
