TMD2621

Proximity Sensor Module for Behind

OLED Applications

The TMD2621 features an advanced proximity measurement.

The device integrates an IR VCSEL and an advanced VCSEL driver

within an optimized 4.65mm x 1.86mm x 1.3mm OLGA package.

The proximity function synchronizes IR emission and detection

to sense nearby objects. The architecture of the engine features

self-maximizing dynamic range, ambient light subtraction,

advanced crosstalk cancellation, and interrupt-driven I²C

communication. Sensitivity, power consumption, and noise can

be optimized with adjustable IR VCSEL timing and power. The

proximity engine recognizes detect/release events and

produces a configurable interrupt whenever the proximity

result crosses upper or lower threshold settings.

Ordering Information and Content Guide appear at end of

datasheet.
