Abstract

The invention provides a reconfigurable digital isolator and electronic equipment, comprising: K channel modules; wherein each channel module comprises a channel circuit, an I / O port and a transmission port, and the channel circuit is respectively connected with the I / O port and the transmission port; K is greater than or equal to 2; the channel circuit is used for obtaining a current state indication; if the current state indication is a sending state indication, entering a sending state; if the current state indication is a receiving state indication, entering a receiving state; wherein the channel circuit in the receiving state can transmit a signal transmitted by the transmission port to the I / O port, and the channel circuit in the sending state can transmit a signal transmitted by the I / O port to the transmission port; the K channel modules comprise N first channel modules and N second channel modules; each group of transmission ports of each first channel module is connected with one group of transmission ports of one second channel module through bonding wires; wherein N is greater than or equal to 1.

Description

technical field [0001] The invention relates to the field of digital isolators, in particular to a reconfigurable digital isolator and electronic equipment. Background technique [0002] The isolator is a kind of isolation principle that uses linear optocoupler, magnetic coupler or capacitive coupling to convert the input signal to output. The input, output and working power are isolated from each other, especially suitable for use with equipment and meters that require electrical isolation. Digital isolators allow circuits to avoid data corruption when communicating with each other, and digitally isolated circuits can transmit data between electrically isolated circuits through digital isolators. [0003] In the prior art, two channel circuits connected to each other can be provided in the isolator chip, and the data transmission mode between the two channel circuits is fixed. For different transmission requirements, multiple different isolation circuits are required. To ...
