Abstract

The present invention provides a current output circuit and device. The circuit includes: a micro-control module for generating a first control signal; a digital-to-analog conversion module for receiving the first control signal and converting and outputting a first voltage signal; a voltage The current conversion module is used to receive the first voltage signal and output the first current signal corresponding to the first voltage signal, and the first current signal is used to drive the external load; the acquisition module is used to collect the power in the voltage-current conversion module The voltage difference between the first and second ends of the tube is used as the first feedback signal and output to the micro-control module; the micro-control module receives the first feedback signal, compares the voltage difference with the preset voltage and generates a second control signal, The second control signal is used to adjust the voltage difference between the first and second ends of the power tube. The current output circuit can dynamically adjust the power consumption inside the circuit according to the load, so as to control the temperature of the chip, prolong the life of the chip, and enhance the reliability of the circuit.

Description

technical field [0001] The invention relates to the technical field of ship control, in particular to a current output circuit and a current output device. Background technique [0002] In recent decades, electronic equipment components required for ship control systems have long relied on imports. However, with the rapid development of domestic chips, domestic chips have been able to meet the various needs of ship control systems. [0003] At the same time, with the continuous development of ship control systems, its complexity is also increasing. As a result, the integration requirements of each module within the ship control system have also increased. [0004] However, with the increase of electronic equipment components in the ship control system, the power consumption of the circuit inside each module is increasing, and with the increase of power consumption, the operating temperature of the circuit also rises accordingly, which will affect the circuit. The service ...
