APPLICATION INFORMATION

interface is easy to access “Proximity Signal” and “Light Intensity” without complex calculation and programming by external

controller. Beside the digital output also a flexible programmable interrupt pin is available.

1. Application Circuit

Fig. 12 - Application Circuit

(x) = Pin Number

Note

• The interrupt pin is an open drain output. The needed pull-up resistor may be connected to the same supply voltage as the application

controller and the pull-up resistors at SDA/SCL. Proposed value R2 should be >1 k

Ω , e.g. 10 kΩ to 100 kΩ.

Proposed value for R3 and R4, e.g. 2.2 k

For detailed description about set-up and use of the interrupt as well as more application related information see AN: “Designing VCNL4010

into an Application”.
