Function Description
Fault Flag
The FLG signal is an N-channel open-drain MOSFET output. FLG is asserted (active-low) when either an over current
or thermal shutdown condition occurs. In the case of and over current condition, FLG will be asserted only after the
flag response delay time, t
D
, has elapsed. This ensured that FLG is asserted only upon valid over current conditions
and that erroneous error reporting is eliminated. For example, false over current condition can occur during hot plug
event when a highly capacitive load is connected and causes a high transient inrush current that exceeds the
current-limit threshold for up to 1ms. The FLG response delay time t
D
is typically 3ms.
Undervoltage Lockout
Undervoltage lockout (UVLO) prevents the output MOSFET from turning on until VIN exceeds approximately 2.5V.
Undervoltage detection function only when the switch is enabled.
