说明

AW93103CSR is 3-channel low-power capacitive controller mainly used for in-ear detection and touch key detection in TWS headset. Each channel can be independently configured as sensor input, shield output.
Advanced self-capacitance technology is adopted, which supports parasitic capacitance compensation for each channel up to 150pF. The device has a high resolution ADC, the minimal capacitance that can be detected is as low as 1fF.
A high performance 32bit MCU is integrated by executing the firmware-program in the ROM, it implements all AFE sampling controlling and complicated data processing algorithms including signal filtering, RF noise suppression, baseline calculation, touch status decision, in-ear detection , etc.
With the proprietary sensing algorithm of AWINIC, the device is able to accurately identify the operations such as putting on and taking off the TWS headset, single tap, double tap, slide and so on.
