BU21170MUV - Capacitive Switch Controller

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.

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. Key Specifications.
  • Power Supply Voltage Range: 3.0V to 5.5V.
  • Operating Temperature Range: -25°C to +85°C.
  • Operating Current: 3.5mA(Typ without load).
  • Scan R.
