TMD2672

Digital Proximity Detector

The TMD2672 family of devices provides a complete proximity

detection system and digital interface logic in a single 8-pin

surface mount module. The devices are register-set and

pin-compatible with the TMD2671 series and includes new and

improved proximity detection features. The proximity

detection includes improved signal-to-noise and accuracy. A

proximity offset register allows compensation for optical

system crosstalk between the IR LED and the sensor. To prevent

false proximity data measurement readings, a proximity

saturation indicator bit signals that the internal analog circuitry

has reached saturation. Interrupts have been enhanced with

the addition of a sleep-on-interrupt feature that also allows for

a single cycle operation. The device internal state machine

provides the ability to put the device in a low-power mode in

between proximity measurements, providing very low average

power consumption.

The proximity detection system includes an LED driver and an

IR LED, which are factory trimmed to eliminate the need for

end-equipment calibration due to component variations.
