Operation in Current Limit
When a heavy load is applied to the output of the
AAT4608, the load current is limited to the value of
I
LIM
determined by R
SET
. See the figure "Overload
Operation". Since the load is demanding more cur-
rent than I
LIM
, the voltage at the output drops. This
causes the AAT4608 to dissipate a larger than nor-
mal quantity of power, and its die temperature to
increase. When the die temperature exceeds an
over temperature limit, the AAT4608 will shut down
until is has cooled sufficiently, at which point it will
startup again. The AAT4608 will continue to cycle
on and off until the load is removed or power is
removed.
Reverse Voltage
The AAT4608 is designed to control current flowing
from IN to OUT. If a voltage is applied to OUT which
is greater than the voltage on IN, large currents may
flow. This could cause damage to the AAT4608.
