Integrated circuit delivering logic levels at a voltage independent from the mains voltage, with no attached regulator for the power section, and corresponding communication module

摘要

The invention concerns an integrated circuit comprising means of delivering, on at least one output, a predetermined output voltage representative of a logic level, means of distributing a mains voltage and means of generating an internal voltage reference lower than the mains voltage, comprising means of connecting the mains voltage to the output and means of limiting and/or detecting the voltage at the output at the predetermined output voltage value, taking into account the reference voltage.
