New Ultra-Compact and Surface Mount Photo-IC Sensor Reduces Power Consumption and Improves Visibility of Display
The TPS859 provides ultra-high sensitivity with light current (IL) of 230microA(1) compared with 40microA(1) in the previous generation TPS852 -- an almost 6x improvement. The device also employs a new optical filtering technology which achieves luminous efficiency near to that of the human eye. The filter is able to reduce the ratio of incandescent to fluorescent light sensitivity (IL) from 1.2 (typ.) in the TPS852 to 1.0 (typ.) for the TPS859. The combination of the 16 percent improvement in the sensitivity ratio and the six-fold increase in sensitivity makes TPS859 the most robust device in the Toshiba ALS product line.
"The ultra-compact surface-mount package expands the potential applications for the TPS859, which could range from large applications such as flat panel displays and various home appliances to small applications including cell phones and digital cameras," explains Roger Shih, business development engineer for the optoelectronics group at TAEC. "In addition, the new filtering technology and the lower operating voltage improve both the sensitivity and the power saving capabilities of the component."
With excellent output linearity across various light sources, Toshiba's RoHS-compatible(2) TPS859 photo-IC ALS features an ultra-compact surface-mount package that measures 1.6 x 1.6 x 0.55 mm. The TPS859 can operate from 1.8V to 5.5V, which makes it ideal for battery-powered applications.
