Capacitive Switch Controllers

ROHM Semiconductor Capacitive Switch Controllers are highly integrated devices that interface via I²C to a host processor to provide a simple solution for adding capacitive switch operation. These capacitive switch controllers integrate sensor data processing and application functions, greatly reducing host CPU load. These low-power devices support up to 20 sensor input channels, with the BU2107 Controller ICs supporting 4x4 and 6x6 sensor matrixes. These ROHM Semiconductor Capacitive Switch Controllers also feature automatic self-calibration if external noise and temperature drift are detected.

BU2107 Capacitive Switch Controller ICs

ROHM Semiconductor BU2107 Capacitive Switch Controller ICs are used for operating switches and feature low power consumption using the intermittent operation mode. The BU2107 supports matrix switches which are arranged in the matrix sensors. The automatic self-calibration is activated if external noise and temperature drift are detected. Included blocks are Analog Front End (AFE) detecting capacitance, A/D converter, MPU, LED ports with PWM function and a 2-wire serial bus interface, power-on-reset, and oscillator. ROHM Semiconductor BU2107 Capacitive Switch Controller ICs operate with a 3.0 to 5.5V single power supply.
