1 / 44 page Digital Ambient Light and UVB Energy Sensor ZOPT2201 Datasheet © 2016 Integrated Device Technology, Inc 1 September 2, 2016 Brief Description The ZOPT2201 Sensor integrates an ambient light sensor (ALS) and ultraviolet energy sensor (UVBS). The device can be connected via an I²C interface to an external microcontroller. Other I²C or SMBus devices can be connected to the same interface. The device has a programmable interrupt with hys- teresis to respond to events and reduce the microcontroller tasks. A major application of the device is in smart phones or other mobile devices to enable brightness control of display panels (ALS) and diverse health care applications or contextual awareness algorithms (UVBS). Features High ambient light and UVB energy sensitivity Superior infrared energy suppression Very stable spectral response over angle of light incidence Wide dynamic range Excellent temperature compensation Lowest conversion repeat noise I²C interface capable of standard mode (100kHz) or fast mode (400kHz) communication; 1.8V logic compatible Programmable interrupt function for ALS and UVBS with upper and lower thresholds ALS Features Integrated ALS closely matches human eye response for high lux accuracy over different light sources Absolute sensitivity: 0.008 lux to 157000 lux Configurable output resolution: 13 to 20 bits Configurable analog gain: x1 to x18 Linear output code 50Hz/60Hz light flicker immunity Fluorescent light flicker immunity UVBS Features Linear UV index measurement (1 to >11) Tailored temperature compensation Physical Characteristics Wide operation temperature: - 40°C to +90°C Wide supply voltage: 1.7V to 3.6V Minimum active current at maximum duty cycle: — ALS: 110µA typical — UVBS: 100µA typical Note: Average current is proportionally lower with lower measurement rates. Low standby current: 1µA typical Packages: — LGA6 (2.0 2.2 0.7 mm) — TSV (1.1 1.2 0.26 mm) ZOPT2201 Application Circuit VDD GND INT SDA SCL SDA SCL VDD1 VDD GND INT ZOPT2201 µC VDD2 VDD2 VDD1: 1.7 to 3.6 V VDD2: 1.7 to 3.6 V |
