Circuit Sense is MCC’s I2C Bus voltage sensing technology. Circuit Sense, when enabled on a device, allows the device to monitor the pull-up Vcc voltage (0.5v to 5v) on the I2C Bus and automatically adjust internal voltage sense circuits to match (0.3Vcc LowMAX, 0.7Vcc HighMIN). A device equiped with Circuit Sense, but with Circuit Sense disabled, will use the pull-up Vcc voltage set by the device.
