The IS31SE5000 uses one infrared LED and 2-channel receivers which pick up the reflectance signal from the photodiodes. When horizontal motion or proximity motion is detected, the flag bits in the status register will be triggered and an interrupt signal is generated to inform the master to read the flag bit through I2C interface.

They project sense fields through any dielectric such as glass or plastic. On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off threshold levels to prevent false sensor activation. They support a fast 400kHz I²C serial bus data transfer with a programmable slave address. An interrupt is generated every time a sense electrode is touched or released 20 February 2015 • 1623 Buckeye Dr. Milpitas, CA. 95035 • 408.969.6600 • [email protected] • www.issi.com Ordering Information Product Selector Guide FxLED Driver No. of Channel No. RGB Group Gamma Correction Control Interface Audio Sync.
