Abstract

The invention discloses a multi-output power management circuit which is in communication connection with an upper computer, wherein the upper computer outputs a power control instruction according toload demands; the multi-output power management circuit comprises a power input interface for inputting a power signal, a plurality of voltage conversion circuits, a controller and a power module; the plurality of voltage conversion circuits are connected with the power input interface separately and are arranged to carry out current and / or voltage conversion; the controller is connected with theupper computer, is provided with a plurality of enable pins connected with the plurality of voltage conversion circuits separately and is arranged to output corresponding enable signals to enable thecorresponding voltage conversion circuits to work to output required electric signals according to the power control instruction; and the power module is connected between the power input interface and a power pin of the controller and provides the controller with electricity. The problems that a traditional power management circuit is complicated in system, high in cost and large in occupied space are solved.

Description

technical field [0001] The invention belongs to the technical field of power supplies, in particular to a multi-output power supply management circuit. Background technique [0002] At present, as mobile robots are widely used in people's daily life and industrial production. More and more modules with different functions are integrated into the robot, which requires the power supply system of the mobile robot to provide corresponding voltage and current for different modules at the same time. In addition, the signal processing circuits on the robot are becoming more and more complex. This kind of hardware circuit has higher and higher requirements on the power supply. At present, the output voltage level of the power supply circuit of most robots is relatively single, so that every time a functional module is added, a power output module must be added, or because the output reserved by the power supply If the power is not enough, other power circuits must be added, which n...
