FFLG Indicator
The MAX4826–MAX4831 feature a current-limit fault
output, FFLG. Whenever a current-limit fault is activat-
ed, FFLG goes low and the switch turns off. FFLG is an
open-drain output transistor and requires an external
pullup resistor from FFLG to IN. During shutdown (ON
is low), the pulldown on the FFLG output is released to
limit power dissipation. FFLG goes low when any of the
following conditions occur:
• The die temperature exceeds the thermal shut-
down temperature limit of +150°C.
• The device is in current limit for more than the
fault-blanking period.
• VIN is below the UVLO threshold.
NOLD Indicator
The MAX4826–MAX4831 feature a no-load flag output,
NOLD (Figure 1). This output is pulled low every time
the current coming out of the switch is less than 10mA
(MAX4826–MAX4829), or 5mA (MAX4830/MAX4831).
NOLD is an open-drain output transistor and requires
an external pullup resistor from NOLD to a supply up to
+5.5V. Current through the switch is intended to be
positive (from IN to OUT), and for currents that are
large in magnitude but negative in sign (OUT to IN),
NOLD asserts low. For options with the autoretry fea-
ture (MAX4827/MAX4829/MAX4831), the NOLD output
is high impedance during the tRETRY period when a for-
ward-current-limit condition is present. However, NOLD
is pulled low if a reverse current-limit condition is pre-
sent during the tRETRY period. A constant time filter is
present at the output of NOLD that gives a 60µs delay
when a no-load condition is asserted. Deassertion of
NOLD is not delayed. During shutdown (ON is low), the
pulldown on NOLD is released to limit power dissipation.
Autoretry (MAX4827/MAX4829/MAX4831)
When the forward- or reverse-current-limit threshold is
exceeded, the tBLANK timer begins counting (Figure 2).
The timer resets if the overcurrent condition disappears
