Embodiment Construction

[0032] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Such as figure 1 As shown, a single-chip integrated fully isolated RS-232 transceiver of this embodiment includes an isolated RS-232 communication module 200 and an isolated power supply module 100. The isolated power supply module 100 is directly used for the isolated RS-232 inside the chip. The -232 communication module 200 provides power, and the isolated RS-232 communication module 200 has an isolated transmission circuit for implementing isolated data transmission. The monolithic integrated fully isolated RS-232 transceiver is also provided with an external interface.

[0034] In this embodiment, the isolation transmission circuit is set in the isolated RS-232 communication module to achieve the purpose of data iso...

Abstract

The invention relates to a monolithic integrated full-isolation RS-232 transceiver, comprising an isolated RS-232 communication module and an isolated power supply module, wherein the isolated power supply module directly supplies power to the isolated RS-232 communication module inside the chip. The isolated RS-232 communication module has an isolated transmission circuit for implementing data isolation transmission. The invention achieves the purpose of data isolation transmission by setting an isolation transmission circuit in the RS-232 communication module, and the isolated RS-232 communication module and the isolated power supply module are integrated and packaged in the same package, thereby realizing the monolithic integrated full isolation of the RS-232 transceiver.

Description

Technical field [0001] The invention relates to a serial communication device, in particular to a monolithic integrated fully isolated RS-232 transceiver. Background technique [0002] Communication interface equipment allows multiple power domains to coexist and communicate. In order to prevent high-voltage hazards and data interference, and improve the anti-interference ability and reliability of interface equipment, power and data isolation must be carried out. The RS-232 interface is currently the most commonly used serial communication device. The RS-232 transceiver chip on the market such as ADM3252 can realize the function of full isolation of power and data, but the single power supply solution with four external charge pump capacitors cannot realize the monolithic integration of charge pump and RS-232 transceiver. This leads to a larger chip area. With the development of application requirements, the functions of RS-232 transceivers also need to be continuously improve...
