General Description
The EAAPMST3923A1 integrates a proximity sensor (PS), an infrared emitting diode (IRED) driver and an SMBus compatible I2C interface into one chip. The fast I2C interface (up to 750 kHz) is for easy connection to a micro-controller or embedded controller. A flexible interrupt scheme is provided for minimal micro-controller utilization. The EAAPMST3923A1 is featuring low power operation, most suitable for battery powered apparatus.
