ISL29101

Small, Low Power, Voltage-Output Ambient Light Photo Detect IC

DATASHEET

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.

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.

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).

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. The compliance of

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.

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.
