AAT4610A
Current Limited Load Switch
General Description
Features
SmartSwitch™
The AAT4610A SmartSwitch is a current limited P-
channel MOSFET power switch designed for high-
side load switching applications. This switch oper-
ates with inputs ranging from 2.4V to 5.5V, making it
ideal for both 3V and 5V systems. An integrated
current-limiting circuit protects the input supply
against large currents which may cause the supply
to fall out of regulation. The AAT4610A is also pro-
tected from thermal overload which limits power dis-
sipation and junction temperatures. It can be used
to control loads that require up to 1A. Current limit
threshold is programmed with a resistor from SET to
ground. The quiescent supply current is typically a
low 9µA. In shutdown mode, the supply current
decreases to less than 1µA.
The AAT4610A is available in a Pb-free 5-pin
SOT23 or 8-pin SC70JW package and is specified
over the -40°C to +85°C temperature range.
