BU21170MUV

Datasheet Capacitive Controller ICs Capacitive Switch Controller IC BU21170MUV General Description BU21170MUV is a capacitive sensor controller for switch operation. BU21170MUV has five sensors and provides the simple switch function by each sensor. If external noise and temperature drift are detected, the automatic self-calibration is operated. Include LED controller with PWM function. Features  5 capacitive sensor ports.  Automatic self-calibration.  Continued touch detection.  LED controller with PWM function.  Inform the detected result of switch operation by interrupt.  2-wire serial bus interface.  Single power supply.  Built-in Power-On-Reset and Oscillator.
