BU21079F - Capacitive Switch Controller
BU21079F is a capacitive switch controller used for operating switches.
Low power consumption is achieved using the intermittent operation mode.
In addition to a regular simple switch, it supports matrix switches which are arranged in the matrix sensors.
If external noise and temperature drift are d
