MAX4881–MAX4884/MAX4893B
Overcurrent Flag Output (
FLAGI)
The MAX4881–MAX4884/MAX4893B have an overcur-
rent-fault flag output (FLAGI) to indicate a current fault
condition. FLAGI asserts low to indicate a fault when the
current reaches the current limit for longer than the 50ms
blanking time. Toggle IN or CB or EN to release FLAGI
latched condition. FLAGI does not assert if the current-
limit fault occurs for less than the blanking time (Figure 5).
FLAGI is disabled when EN goes high. When CB is low,
the switch opens, but FLAGI is not active.
FLAGI is an open-drain active-low output. Connect a
pullup resistor from FLAGI to the logic I/O voltage of the
host system or to any voltage source up to 6V.
Current-Limit Switch
When the forward- or reverse-current-limit threshold is
exceeded, tBLANK timer begins counting. The timer
