Description
AI
The NOA3302 combines an advanced digital proximity sensor and LED driver with an ambient light sensor (ALS) and tri-mode I2C interface with interrupt capability in an integrated monolithic device. Multiple power management features and very low active sensing power consumption directly address the power requirements of battery operated mobile phones and mobile internet devices.
