Ct8527 is a capacitive in ear detection touch chip with voltage detection and reset function. It is manufactured by CMOS process and based on MCU base, with high performance and low power consumption. Built in anti-interference circuit and environment self calibration circuit.

The chip has three detection input channels: in ear detection input, touch detection input and reset voltage detection input. In ear and touch are output in two separate channels. The chip can output a variety of application modes through MCU software configuration.

The chip can be widely used in TWS, smart home, touch bracelet, AI intelligence and other DC touch key detection products to realize product intelligence.
