General Description
Figure 1:
Added Value of Using TMD3700
The device features advanced Proximity measurement, Digital
Ambient Light Sensing (ALS) and Color Sensing (CRGB). The slim
module incorporates an IR LED and factory calibrated LED
driver. The Proximity detection feature provides object
detection (e.g. mobile device screen to user’s ear) by
photodiode detection of reflected IR energy (sourced by the
integrated LED).
Detect/release events are interrupt driven, and occur when
proximity result crosses upper and/or lower threshold settings.
The proximity engine features offset adjustment registers to
compensate for unwanted IR energy reflection at the sensor.
Proximity results are further improved by automatic ambient
light subtraction. The Color and ALS detection feature provides
red, green, blue and clear light intensity data. Each of the C, R,
G, B channels have a UV and IR blocking filters and a dedicated
data converter producing16-bit data simultaneously. This
architecture allows applications to accurately measure ambient
light and sense color which enables devices to calculate
illuminance and color temperature, control display backlight,
and chromaticity.
