CT8527 is a capacitive in-ear detection touch chip with voltage detection and reset function, manufactured by CMOS process, based on MCU Base, high performance, low power consumption. Built-in anti-interference circuit and environmental self-calibration circuit.

      The chip has three detection input channels: ear detection input, touch detection input, and reset voltage detection input. Ear and touch are output in two separate channels, and the chip can output multiple application modes through MCU software configuration.

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