Optical Sensor Si1151-AB00-GM
Si1151-AB00-GM contains the following:
- IR Proximity sensor
- Long range
- Low power
- High sensitivity with a various amount of LED drivers in a 2x2 DFN 10 pin package
Key benefits
- Module simplifies optics and eliminates need for on board blocking/lensing
- Module has matched LED and Filter for optimum performance in sunlight
- Can add additional external LEDs for gesture applications
- No need for additional blocking
- Up to 3 LED drivers and up to 360mA drive through each
- Module version occupies 1 leaving 2 for external use
- Packaged as integrated module with LED, or as a standalone sensor
- Long range capabilities up to 2 meters
- Dual ADCs / Dark current cancellation
Operation
Forced
- Host commands an IR or ALS reading and reads the resulting value
- Can be configured to generate an interrupt after reading to free the host
- Typically 155us for a conversion
Autonomous
- Si115x will update the ALS and IR registers automatically at a frequency selected by the ho
Can also be set to generate an interrupt based 3 factors
- Any measurement
- Any measurement above OR below a set threshold
- Any measurement that leaves a specific threshold “window”
Benefit
- Flexibility for the host and specific modes based on power to performance ratio required as well as application
