General Description

The BS801C/02C/04C/06C/08C 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 de-

vice integration enable applications to be implemented

with a minimum number of external components.

Special internal circuitry is also employed to ensure

excellent power noise rejection to reduce the possibility

of false detections, increasing the touch switch applica-

tion reliability under adverse environmental conditions.

With auto-calibration, low operating current and a low

power one-key operating state, this range of touch key

devices provides a simple and effective means of imple-

menting touch switches in a wide variety of applications.

The BS804C and BS808C are equipped with a One-line

serial interface to allow easy communication with an exter-

nal MCU for device setup and for touch pin monitoring pur-

poses.
