General Description

The BS801B/02B/04B/06B/08B are a range of 1 to 8 key

touch key devices which can detect human body contact

using external touch pads. The high level of device

integration enable applications to be implemented with

a minimum number of external components.

The BS804B and BS808B are equipped with a One-line

serial interface to allow easy communication with an external

MCU for device setup and for touch pin monitoring purposes.

Special internal circuitry is also employed to ensure

excellent power noise rejection to reduce the possibility

of false detections, increasing the touch switch application

reliability under adverse environmental conditions.
