Hamamatsu Photonics introduce a new RGB colour sensor Photo IC, the S11059-78HT. The new device features I2C compatibility and uses a small and highly reliable WL-CSP (Wafer Level Chip Size Package). To ensure low power consumption this sensor includes an auto-sleep function that automatically switches the detector to standby after a detection event. Another attractive feature of these devices is the ability to use lead-free reflow soldering, which improves the cost and speed of the manufacturing process.
The new devices compact size (1.18 x 1.68 x 0.58 mm) and simplicity of integration with products implementing the I2C protocol makes them ideal for LCD backlight and RGB-LED brightness adjustment in flat panel televisions and mobile phones.
