CT8517 is a capacitive in-ear detection touch chip with voltage detection reset function. Manufactured by CMOS process, based on MCUBase, high performance, low power consumption, it is mainly used in the Bluetooth master control solution of high-level power-on with touch output.

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 modes through MCU software control.

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.
