  • Discharge circuit integrated in chip of slave device to follow bus rectifier bridge
    Patent number: 10545564
    Abstract: A discharge circuit integrated in a chip of a slave device to follow a bus rectifier bridge includes: a digital control module for generating, when an output result of a comparator is that a bus voltage falls, a high-level and time-configurable pulse width to drive a discharge circuit to discharge a bus; a discharge current source module for enabling the discharge of the bus by means of a digital control module and adjusting a discharge current; a comparator for obtaining a status of a change in the bus voltage; and a peripheral circuit for monitoring the change in the bus voltage, providing to the comparator a voltage signal which reflects divided bus voltage fall information, and generating a comparison reference voltage.
