Ambient Light Sensor ICs

ROHM ambient light sensor ICs are designed to detect the brightness over a wide range, from, from darkness to direct sunlight, and output the data in order to adjust LCD brightness for optimum visibility and lower power consumption. The lineup is offered in different output types (i.e. current, comparator, digital) for maximum compatibility.

Broad Lineup Ambient Light Sensor ICs

| Analog Current Output Type Ambient Light Sensor ICs | Digital 16bit Serial Output Type Ambient Light Sensor ICs | Single Chip Optical Proximity + Ambient Light Sensor IC |

Analog Current Output Type Ambient Light Sensor ICs Uniform sensitivity regardless of light source Built-in shutdown function Wide output range	Digital 16bit Serial Output Type Ambient Light Sensor ICs 16bit ADC and direct output utilized for high accuracy measurement(except BH1730FVC) Operation with 2 lines of ADC output makes it possible to suitable for various color of optical window(BH1730FVC) I²C I/F compatible with voltages from 1.65V to Vcc(3.6V max.)

Single Chip Optical Proximity + Ambient Light Sensor IC With combination of IrLED (Rohm:SIM-030 recommended), it realizes proximity sensing(BH1772GLC) It can detect proximity of 1 to 10cm by the proximity output of 8bit digital value (log compression).
