Operation in Current Limit
When a heavy load is applied to the output of the
AAT4610A, 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 current than I
LIM
, the voltage at the output
drops. This causes the AAT4610A to dissipate a
larger than normal quantity of power, and its die
temperature to increase. When the die temperature
exceeds an over temperature limit, the AAT4610A
will shut down until is has cooled sufficiently, at
which point it will startup again. The AAT4610A will
continue to cycle on and off until the load is
removed, power is removed, or until a logic high
level is applied to ON (pin 4).
Enable Input
In many systems, power planes are controlled by
integrated circuits which run at lower voltages than
the power plane itself. The enable input ON (pin 4)
of the AAT4610A has low and high threshold volt-
ages that accommodate this condition. The thresh-
old voltages are compatible with 5 volt TTL, and 2.5
volt to 5 volt CMOS.
Reverse Voltage
The AAT4610A is designed to control current flow-
ing from IN to OUT. If a voltage is applied to OUT
which is greater than the voltage on IN, large cur-
rents may flow. This could cause damage to the
AAT4610A.
