Distribution Spotlight Innovations Embedded Ambient Light Sensor ICs for LCD Display Backlighting ROHM ambient light sensor (ALS) ICs (BH16xx analog/BH17xx digital) are designed to control the brightness of LED-backlit LCD displays based on ambient light for optimum visibility and energy efficiency. These compact ALS ICs are the ideal choice for LCD-equipped portable devices as well as LCD monitors and high-defenition (HDTV) backlight control. Applications Key Features LCD-equipped devices • Mobile phones • Digital cameras • Video players • Notebook PCs • Car navigation systems • LCD TVs • LCD monitors/displays • Higher light-sensing accuracy: ±15% compared to competitive devices that range from ±30% to ±55% • More stable ambient light detection: ±10% maximum difference regardless of light source (vs. comparable products with up to 4x the variation) • Wide operating temperature range: -40°C to 85°C • Wide light detection range: up to 100,000 lux • Small, surface-mount package • RoHS-compliant and halogen-free Pricing Quantity per reel: 3,000 pieces Price: $0.58 – $2.25 Analog Output Digital Output (up to 16bit) Brightness Control Microcontroller or Baseband Processor •DC •PWM •I2C I2C I/F ALS (BH16xx) ADC IOUT GC2 Driver S/W more info: click here GC1 GC2 LED Driver Microcontroller or Baseband Processor LED Driver Light Driver S/W SCL ALS (BH17xx) SDA SCLGC2 SDA Light Gain Control visit us: www.rohm.com
