Pin Function
Switch A Enable (Input): Logic-compatible, enable input. Active high (-1) or
active low (-2).
Fault Flag A (Output): Active-low, open-drain output. Low indicates overcurrent
or
thermal
shutdown
conditions.
Overcurrent
conditions
must
last
longer
than

B
in order to assert FLGA. FLGA pin can be left floating; however, fault status
information will not be available.
Fault Flag B (Output): Active-low, open-drain output. Low indicates overcurrent
or
thermal
shutdown
conditions.
Overcurrent

Switch B (Output)
Ground
Input: Switch and logic supply input.
