TCS3701 ALS/Color and Proximity Sensor for Use Behind OLED Displays The TCS3701 features ambient light and color (RGB) sensing in General Description parallel with proximity detection. The device comes in a low-profile and small footprint, L2.5mm x W2.0mm x H0.5mm package. The Ambient Light and Color Sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB and Clear channels have a UV/IR blocking filter. This architecture accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The Proximity function synchronizes IR emission and detection to sense nearby objects. The internal IR LED driver needs to be connected to an external emitter. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced crosstalk cancelation, 14-bit data output and interrupt-driven IC communication. Sensitivity, power consumption, and noise can be optimized with adjustable IR LED 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. ams Product Brief Page 1 v1-03 2018-Dec-19 Document FeedbackT C S3701 Key B e nefits & F e atur es The benefits and features of TCS3701 are listed below: Key Benefits & Features Figure 1: Added Value of Using TCS3701 Benefits Featur es Configurable, high sensitivity Programmable gain and integration time 1024x dynamic range by gain adjustment only 1mlux minimum detectable illuminance (100ms) Invisible ALS and color sensing under any glass type Tailored ALS and color response UV/IR blocking filter for RGBC channels Wideband reference channel without filters ALS/color interrupt with thresholds Capable to drive external IR emitter LED or VCSEL Crosstalk and threshold calibration on chip Invisible proximity detection behind OLED displays Programmable timings and sensitivity Calibrated LED output power 1.8V operation DD Low power consumption and minimum IC Configurable sleep mode traffic Interrupt-driven device On-chip self-calibration of ALS and proximity functions Digital and analog ALS saturation flags Integrated status checking for all functions Proximity saturation flag TCS3701 integrates multiple applications within one device.
