TSM12触摸电子锁专用触摸芯片

TSM12低功耗触摸芯片

General
The TSM12 is 12-Channel capacitive sensor with auto sensitivity calibration. And the supply voltage range is from 1.8 to 5.0V.
The TSM12 has the IDLE mode to save the consumption. And the current consumption is 10 uA.
The TSM12 offers special functions. One is an embedded power key function on channel 1 for mobile phone application. The other is the sync function for multi chip application.
The result of touch sensing can be checked by the I2C serial interface. And touch intensity can be detectable within 3 steps (Low, Middle and High).
