8 Keys BS818A-2 Touch Switch IC , Common IC Chips With Sensitivity Adjustment

Description

The BS81x is a series of 2~16 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 BS81x series devices are equipped with serial or parallel interfaces 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 standby current, excellent resistance to voltage fluctuation and other features, this range of touch key devices provide a simple and effective means of implementing touch key operation in a wide variety of applications.

Feature

• Operating voltage: 2.2V~5.5V
• Low standby current
• Auto-calibration
• Reliable touch detections
• Standby and normal operating modes
• Maximum key on duration time detection
• Adaptive voltage drop function
• Level Hold, selectable active level- low or high
• NMOS output with internal pull-high/CMOSDirect Output
• Both serial interface and parallel outputs
• Sensitivity adjustment using an external capacitor
• Minimal number of external components
