DATASHEET ISL29101 FN6510 Rev 1.00 November 5, 2012 Small, Low Power, Voltage-Output Ambient Light Photo Detect IC The ISL29101 is a low power ambient Light-to-Voltage optical sensor combining a photodiode array, a current amplifier and a micropower operational amplifier on a single monolithic IC. Similar to the human eye, the photodiode array has a peak response at 550nm and spans from 400nm to 600nm, rejecting UV light and IR light. The output voltage is proportional to the visible light intensity from 0.5 lux up to 10,000 lux. However, the input luminance range can go up to 30,000 lux with some compromise in linearity. A dark current compensation circuit aids the photodiode array to minimize temperature dependent leakage currents in the absence of light, improving the light sensity at low lux levels. Features • 0.5 lux to 10,000 lux range • 1.8V to 3.3V supply range • Low supply current • Fast response time • Excellent linearity of output voltage vs light intensity • Close to human eye response • Good IR rejection • Internal temperature compensation Housed in an ultra-compact surface mount 2mmx2.1mm ODFN clear plastic package, this device is excellent for power saving control functions in cell phones, PDAs, and other handheld applications. • Operating temperature range -40°C to +85°C Ordering Information Applications PART NUMBER (Notes 2, 3) • Ultra-compact surface mount package • Pb-free (RoHS compliant) TEMP.

TRANSIENT RESPONSE OF ISL29101 TO CHANGE IN LIGHT INTENSITY Page 5 of 7 ISL29101 the ISL29101’s output circuit may result in premature saturation when an excessively large REXT is used. The output compliance voltage is 700mV below the supply voltage, as listed in VO-MAX of the “Electrical Specifications” table on page 2. Application Information Light-to-Voltage Conversion The ISL29101 has responsiveness that is a linear function of the light intensity intercepted by the photodiode in lux. Because the photodiode has a responsivity that resembles the human eye, conversion rate is independent of the light source (fluorescent light, incandescent light or direct sunlight). V OUT = 1.6A 100lux E R EXT Optical Sensor Location Outline The green area in Figure 17 shows the optical sensor location outline of ISL29101. Along the pinout direction, the center line (CL) of the sensor coincides with that of the packaging. The sensor width in this direction is 0.39mm. Perpendicular to the pin-out direction, the CL of the sensor has an 0.19mm offset from the CL of packaging away from pin-1. The sensor width in this direction is 0.46mm. (EQ. 1) Here, VOUT is the output voltage and E is the light intensity. REXT is the value of the external resistor, which is used to set the light-to-voltage scaling constant.
