AAT4290/91
I/O Expander Load Switches with Serial Control
General Description
Features
SmartSwitch™
The AAT4290 and AAT4291 SmartSwitch products
• 1.8V to 5.5V Input Voltage Range
are members of AnalogicTech’s Application
• 5 or 3 Independent Load Switches
Specific Power MOSFET™ (ASPM™) product
• S2Cwire Interface
family. The AAT4290 and AAT4291 are five and
three P-channel MOSFETs, respectively, config-
• 1.1Ω RDS(ON) Per Switch
• Low Quiescent Current
ured for use as a microprocessor I/O expander.
— 5µA
Having independent drain outputs and a common
— 0.1µA in Shutdown
source input, they operate with an input voltage
• -40°C to +85°C Temperature Range
ranging from 1.8V to 5.5V, making them ideal for
• 8-Pin SC70JW Package
2.5V, 3.3V, or 5V systems, as well as systems pow-
ered by lithium-ion/polymer batteries. Each switch
features a 500ns turn-on time. The switch states
are controlled by AnalogicTech’s Simple Serial
Control™ (S2Cwire™) interface which permits ease
Applications
of control and efficiency of size. The quiescent
supply current is very low, typically 5µA. In shut-
down mode, the supply current is reduced to less
than 1µA.
• Cell Phones
• I/O Expansion
• Multiple Low Power Switching
• Personal Communication Devices
The AAT4290 and AAT4291 are offered in a Pb-
• Portable Electronic Devices
free, 8-pin SC70JW package specified over the
-40°C to +85°C temperature range.
