PI FU CTIO S
ADIN (QFN Package): ADC Input. A voltage between 0V
and 1.235V applied to this pin is measured by the onboard
ADC. Tie to ground if unused.
ADR0, ADR1, ADR2 (ADR1, ADR2 Available in QFN Pack-
age): Serial Bus Address Inputs. Tying these pins to ground,
to the INTV
addresses. See Table 1 in Applications Information.
⎯ A ⎯ L ⎯ E ⎯ R ⎯ T : Fault Alert Output. Open-drain logic output
that is pulled to ground when a fault occurs to alert the
host controller. A fault alert is enabled by the ⎯ A ⎯ L ⎯ E ⎯ R ⎯ T

if unused.
⎯ E ⎯ N : (QFN package) Enable Input. Ground this pin to
indicate a board is present and enable the N-channel
MOSFET to turn on. When this pin is high, the MOSFET
is not allowed to turn on. An internal 10µA current source
pulls up this pin. Transitions on this pin are recorded in
the Fault register. A high-to-low transition activates the
logic to read the state of the ON pin and clear Faults. See
Applications Information.
