APDS-9130 Digital Proximity Sensor Data Sheet Description Features The APDS-9130 provides IR LED and a complete proximity IR LED and Proximity Detector in an Optical Module detection system in a single 8 pin package. The proximity Proximity Detection function offers plug and play detection to 100 mm Fully Calibrated to 100 mm Detection (without front glass) thus eliminating the need for factory Integrated IR LED and Synchronous LED Driver calibration of the end equipment or sub-assembly. The Eliminates Factory Calibration of Prox proximity detection feature operates well from bright Programmable Wait Timer sunlight to dark rooms. The wide dynamic range also Wait State Power 90 A Typical allows for operation in short distance detection behind dark glass such as a cell phone. Programmable from 2.7 ms to > 8 sec 2 I C Interface Compatible The proximity function is targeted specifically towards 2 Up to 400 kHz (I C Fast-Mode) near field proximity applications. In cell phones, the Dedicated Interrupt Pin proximity detection can detect when the user positions the phone close to their ear. The device is fast enough Sleep Mode Power - 2.2 A Typical to provide proximity information at a high repetition Small Package L3.94 x W2.36 x H1.35 mm rate needed when answering a phone call. This provides Applications both improved green power saving capability and the added security to lock the computer when the user is not Cell Phone Touch-screen Disable present. The addition of the micro-optics lenses within Notebook/Monitor Security the module, provide highly efficient transmission and Automatic Speakerphone Enable reception of infrared energy which lowers overall power Automatic Menu Pop-up dissipation.

The reduce the need for factory calibration that is required digital output of the APDS-9130 device is inherently more for most discrete proximity sensor solutions. While the immune to noise when compared to an analog interface. APDS-9130 is factory calibrated at a given pulse count, The APDS-9130 provides a separate pin for level-style the number of proximity LED pulses can be programmed interrupts. When interrupts are enabled and a pre-set from 1 to 255 pulses, which will allow greater proximity value is exceeded, the interrupt pin is asserted and distances to be achieved. Each pulse has a 16 s period. remains asserted until cleared by the controlling firmware. The interrupt feature simplifies and improves system efficiency by eliminating the need to poll a sensor for a proximity value. An interrupt is generated when the value of proximity conversion exceeds either an upper or lower threshold. Additionally, a programmable interrupt per- sistence feature allows the user to determine how many consecutive exceeded thresholds are necessary to trigger an interrupt. Interrupt thresholds and persistence settings are configured independently for proximity. 2 2 I C Interface
