APPLICATION INFORMATION
Error Flag
An error Flag is an open-drained output of an
N-channel MOSFET. FLG output is pulled low to
signal
the
following
fault
conditions:
input
undervoltage, output current limit, and thermal
shutdown.
the thermal shutdown function will only turn off
the switch that is in overcurrent condition and the
other switch can still remain its normal operation.
In other words, the thermal shutdown function of
the two switches is independent of each other in
the case of overcurrent fault.
Current Limit
The current limit threshold is preset internally. It
protects the output MOSFET switches from
damage resulting from undesirable short circuit
conditions or excess inrush current, which is often
encountered during hot plug-in. The low limit of
the current limit threshold of the AIC1529 allows a
minimum current of 1A through the MOSFET
switches. The error flag signals when any current

device,
is
strongly
recommended to control supply transients.
Without a bypass capacitor, an output short may
cause sufficient ringing on the input (from supply
lead inductance) to damage internal control
circuitry.
USB supports dynamic attachment (hot plug-in)
Thermal Shutdown
When temperature of AIC1529 exceeds 135°C
for any reasons, the thermal shutdown function
turns both MOSFET switches off and signals the
error flag. A hysteresis of 10°C prevents the
MOSFETs from turning back on until the chip
temperature drops below 125°C. However, if
