描述 Description

The TMD2672 family of devices provides a complete proximity detection system and digital interface logic in a single 8-pin surface mount module. The device is 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.
