Description

The SX9210 is a capacitive controller used in wearable and hearable applications where package size, power consumption and small sensors are of special importance.

The SX9210 can use any of its three sensor inputs along with its Smart Sense Engine for features such as in-ear detection, on-table detection and proximity detection to intelligently power on/off, play/pause, change volume, as well as many other features specific for wearable/hearable applications.

Operating directly from an input supply voltage of 1.7 to 2V, the SX9210 outputs its data via I2C serial bus. The I2C serial communication bus port is compatible with 1.8V host control to report body detection/proximity and to facilitate parameter settings adjustment. Upon detection, the NIRQ output asserts, enabling the user to either determine the relative proximity distance, or simply obtain an indication of the type of detection.

The SX9210 includes an on-chip auto-calibration controller that regularly performs sensitivity adjustments to maintain peak performance over a wide variation of temperature, humidity and noise environments, providing simplified product development and enhanced performance.
