... Auto-calibration High reliability touch detections High PSRR General Description The BS801B/02B/04B/06B/08B are a range key touch key devices which can detect human body con- tact using external touch pads. The high level of device integration enable applications to be implemented with a minimum number of external components. ...

... Mode and the Normal Mode. After the device is powered up it will automatically enter the Standby Mode to con- serve power. The BS801B and BS802B devices can then be woken up by touching any of their Keyn pins. The BS804B, BS806B and BS808B devices can how- ever be woken up by either a One-key Wake-up using Key0 Any-key Wake-up ...

... BS80xB device. Therefore the sensitivity will vary according to the actual PCB layout and design. Rev. 1.00 BS801B/02B/04B/06B/08B An external capacitor, Cs, connected to the Cref pin, is used to set the overall sensitivity of all pins. Some of the most important factors affecting sensitivity are the fol- ...
