MAX44000GDT+T

The MAX44000GDT+T is an ambient and infrared proximity sensor in 6 pin OTDFN package. This industry's lowest power integrated ambient light and proximity sensor provides reliable measurements combines wide dynamic range ambient light sensor with an integrated infrared proximity sensor. 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 ability to make wide dynamic range from 0.03lux to 65535lux measurements. An on-chip IR proximity detector is matched with an integrated IR LED driver. A programmable interrupt pin minimizes need to poll device for data, freeing up microcontroller resources, reducing system software overhead and educing power consumption. It has low power operation (5μA in ambient mode, 7μA in ambient plus proximity mode, 70μA in ambient plus proximity mode including 100mA LED current).

• Supply voltage range from 1.7V to 3.6V
• Operating temperature range from -40°C to 105°C
• I2C communication bus and internal ambient cancellation
• Excellent light source matching, programmable green and IR channel gains
• Integrated single pulse IR LED driver and 10mA to 110mA programmable range
• Maximum ambient light sensitivity of 0.03lux/LSB and quiescent current proximity of 375μA
• Gain error of 15% (green LED 538nm response, TA = +25°C)
• Maximum proximity detection sensitivity of 1.5mW/cm2/LSB
• Quiescent current (ambient mode) of 5μA and software shutdown current of 0.1μA
• Designed to drive an external IR LED and can operate from 1.7V to 3.6V VDD
