BU21078MUV Datasheet (ROHM) - Capacitive Switch Controller

BU21078MUV, Capacitive Switch Controller

BU21072MUV/BU21078MUV/BU21078FV is a capacitive sensor controller for switch operation.

In addition to a regular simple switch, support matrix switches which are arranged in the matrix sensors.

If external noise and temperature drift are detected, the automatic self-calibration is operated.
