Capacitive Switch Controller ICs - BU21079F

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 detected, the automatic self-calibration is activated.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
