AAT4295

Single/Dual RGB Controller

Skyworks Solutions 

General Description

The AAT4295/97 SmartSwitch is a member of Skyworks'

Application Specific Power MOSFET (ASPM™) product

family. The AAT4295/97 is comprised of three/six low-side

N-channel MOSFET switches that gate an applied load to

ground. This device is intended for controlling RGB fash-

ion 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 limitations by eliminating the

need for multiple GPIO control lines and discrete MOSFETs

to control product features.

The state of each output channel is controlled with a

single GPIO line via the EN/SET pin using Skyworks'

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 configuration. In the enabled state, the

AAT4295/97 typically consumes less than 3μA of quies-

cent 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.

The AAT4295 and AAT4297 operate over an input volt-

age range of 1.8V to 5.5V, making them ideal for bat-

tery-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.
