The BS801B is a 1-button touch key device that can detect human contact using an external touchpad. A high level of device integration allows applications to be implemented with a minimum of external components. Special internal circuitry is also employed to ensure good power noise rejection, reducing the possibility of false detection and increasing reliability in touch switch applications under adverse environmental conditions. With automatic calibration, low standby current and wake-up function options, this series of touch key devices provides a simple and effective means of implementing touch switches in a wide range of applications.
