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 device integration enable applications to be implemented with a minimum number of external components.The BS804C and BS808C are equipped with a One-lineserial 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.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 implementing touch switches in a wide variety of applications.
