FLAG Indicator
FLAG is an open-drain fault indicator output and requires
an external pullup resistor to a DC supply. FLAG goes
low when any of the following conditions occurs:
"   The device is in current-limit mode.
"   The OUT voltage is above the IN voltage by more
than 110mV (typ).
"   The die temperature exceeds the thermal-shutdown
temperature limit of +150癈.
"   SETI is connected to ground.
Thermal Shutdown
Thermal-shutdown circuitry protects the devices from
overheating. The switch turns off and FLAG goes low
immediately when the junction temperature exceeds
+150癈 (typ). The switch turns on again after the device
temperature drops by approximately 15癈 (typ).
