Enhanced Touch Key

Features

General Description

• Operating voltage: 2.2V~5.5V

• Low standby current

• Auto-calibration

The BS81x is a series of 1~16 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.

• Reliable touch detections

• Standby and normal operating modes

• Maximum key on duration time detection

• Adaptive voltage drop function

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.

• Level Hold, selectable active level-low or high

• NMOS output with internal pull-high/CMOS-

Direct Output

• Both serial interface and parallel outputs

• Sensitivity adjustment using an external capacitor

• Minimal number of external components

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.

Selection Table

For this device series, most of the feature are similar. The BS818C-3, BS8112C-3 and BS8116C-3 provide I²C

function. The BS814C-2 and BS818C-2 include a serial interface function while the BS811C-1, BS812C-1,

BS813C-1, BS814C-1 and BS816C-1 have parallel outputs. Meanwhile the BS818C-3, BS8112C-3 and

BS8116C-3 can set up some options and the sensitivity through the I²C communication interface and the

BS816C-1 and BS818C-2 include two hardware options. The following table summarizes the main characteristics

of each device.
