BS801B - (BS801B - BS808B) Touch Key

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.

Key Features

  • Operating voltage: 2.2V~5.5V.
  • Ultra low standby current: 1.5mA at 3V.
  • Auto-calibration.
  • High reliability touch detections.
  • High PSRR.
  • Output type: Level-hold or Toggle.
  • One-key or Any-key Wake-up Mode.
  • Wake-up Mode set by pins or serial command.
  • Open drain NMOS output.
  • Key status monitored using pins or serial bus General.
