AAT4295/97
Single/Dual RGB Controller
™
SmartSwitch
General Description
Features
The AAT4295/97 SmartSwitch is a member of
AnalogicTech's Application Specific Power MOS-
FET™ (ASPM™) product family. The AAT4295/97
is comprised of three/six low-side N-channel MOS-
FET switches that gate an applied load to ground.
This device is intended for controlling RGB fashion
lighting in portable products; it can also be used for
a combination of general purposes where a load
requires a low-side switch connection to ground.
The AAT4295/97 simplifies design and layout limi-
tations by eliminating the need for multiple GPIO
control lines and discrete MOSFETs to control
product features.

— AAT4295 in 8-Pin SC70JW
— AAT4297 in 12-Pin TSOPJW
The state of each output channel is controlled with a
single GPIO line via the EN/SET pin using
AnalogicTech's Simple Serial Control™ (S2Cwire™)
interface. After a short set of data pulses is sent to
the EN/SET input and the line is pulled to logic high,
the device is enabled with the desired switch config-
uration. In the enabled state, the AAT4295/97 typi-
cally consumes less than 3µA of quiescent current.
When EN/SET is pulled to a logic low, the device is
disabled and each output switch is placed in a high
impedance open state.

Portable Electronic Devices
The AAT4295 and AAT4297 operate over an input
voltage range of 1.8V to 5.5V, making them ideal for
battery-powered applications. The three-switch
AAT4295 is offered in a Pb-free, 8-pin SC70JW
package, while the six-switch AAT4297 is offered in a
Pb-free, 12-pin TSOPJW package. Both devices are
rated over the -40°C to +85°C temperature range.
