ZOPT3100 Digital RGB/Ambient Light + Proximity Sensor IC Brief Description ALS Features The ZOPT3100 Sensor IC integrates an ambient light sensor (ALS), a color sensor (CS), and a proximity sensor (PS), as well as an LED driver on a single chip. The device is connected by an I²C™* interface to a microcontroller. Other I²C™ or SMBus devices can be connected to the same interface. The device has a programmable interrupt with hysteresis to respond to events and reduce the microcontroller tasks. Dynamic range : 0.006 lux to 32,000 lux ALS measurement uses CS green filtered values Temperature compensation CS/ALS output resolution: 14 to 18 bits Linear output code 50ms conversion rate for 14-bit resolution 50Hz/60Hz light flicker immunity Fluorescent light flicker immunity The device allows adjusting the brightness as well as the color of the display panel. This device can also measure distance in parallel with ALS and CS measurements in order to deactivate the touch screen during phone calls. CS Features Temperature compensation CS/ALS output resolution: 14 to 18 bits Linear output code 50ms conversion rate for 14-bit resolution 50Hz/60Hz light flicker immunity Fluorescent light flicker immunity Features 5 integrated photodiodes (1 proximity diode and 4 diodes for white, green, blue, and red channels) 5 analog-to-digital converters (ADCs) to measure PS in parallel to ALS/CS I²C™ capable of standard mode (100kHz) or fast mode (400kHz) communication; 1.8V logic compatible Programmable interrupt function for ALS (green channel) and PS with upper and lower thresholds PS measurement parallel to ALS/CS measurements Many measurement modes: PS+ALS+CS, ALS+CS, PS+ALS, PS only, ALS only, CS only Physical Characteristics Wide operation temperature: -40 to +90 °C Wide supply voltage: 2.4 to 3.6 V Low supply current: < 200µA (LED driver excluded) Low standby current: < 2µA ZOPT3100 Application Circuit VDD PS Features High ambient light suppression Built-in LED driver and detector Detection of movement (in/out) Cancelation of crosstalk (lowest PS value is stored and subtracted from output value to memorize the reflection quantity) Programmable pulsed LED driver: up to 125mA output current 11-bit resolution * I2C is a trademark of NXP.
