MAX44000
Ambient and Infrared Proximity Sensor
General Description
The MAX44000 combines a wide-dynamic range ambient
light sensor with an integrated infrared proximity sensor. The
IC is a perfect solution for touch-screen portable devices.
The IC can consume as low as 11μA (time averaged) in
ambient light sensing plus proximity sensing, including
external IR LED current.
The on-chip ambient sensor has the ability to make wide
dynamic range 0.03 lux to 65,535 lux measurements. An
on-chip IR proximity detector is matched with an inte-
grated IR LED driver. All readings are available on an
I 2 C communication bus. A programmable interrupt pin
minimizes the need to poll the device for data, freeing
up microcontroller resources, reducing system software
overhead, and ultimately, reducing power consumption.
Features
S Tiny, 2mm x 2mm x 0.6mm UTDFN-Opto Package
S V DD = 1.7V to 3.6V
S Low-Power Operation
5μA in Ambient Mode
7μA in Ambient Plus Proximity Mode
70μA in Ambient Plus Proximity Mode,
Including 100mA LED Current
S Excellent Light Source Matching
Programmable Green and IR Channel Gains
S Integrated Single-Pulse IR LED Driver
10mA to 110mA Programmable Range
Internal Ambient Cancellation
S -40 N C to +105 N C Temperature Range
The IC is designed to drive an external IR LED and can
operate from a V DD of 1.7V to 3.6V. It consumes just 5μA
operating current when only the ambient light sensor is
enabled and 7μA when the proximity receiver and driver
are enabled.
