Embodiment Construction

[0035] figure 1 is a schematic diagram of a system 1 involving a multi-logic power management integrated circuit (MTPMIC) 2 . The server 3 stores program code 4 , information 5 using the MTPMIC2 as a reference design, debugger 6 , and development kit software 7 . The server 3 can store a large number of reference designs using the MTPMIC2, where each reference design and corresponding program codes have been thoroughly verified by the power company that produces the MTPMIC2 and runs the server 3.

[0036] Computer 8 is paired with server 3 via network 9 . A user uses a computer 8 to access a website supported by the server 3 and download information about MTPMIC2 and reference designs from the website. Using this information, the user can assemble the reference design or other user-specific circuits based on the reference design. In the example given, the user assembled circuit 10 is the reference design. Circuit 10 includes MTPMIC2 and a corresponding amount of external h...

Abstract

Provided is a multi-logic unit power management circuit (MTPMIC), comprising a plurality of logic units including an MCU / ADC logic unit and a power management logic unit. The power management logic unit comprises one set of components capable of configuring a switching power supply pulse width modulator (CSPSPWM). The combinations and external circuits of other integrated circuits can be together configured to form one of a plurality of selected switching power supply circuits. In powering up, an internal voltage stabilizer supplies power for the CSPSPWM; and then, the CSPSPWM controls a power supply and starts to switch to a low frequency starting mode; according to the external circuits of integrated circuits, the CSPSPWM determines a current detection method in a starting period; a power supply voltage is supplied to a processor in the MCU / ADC logic unit through leads of a standard bus; the processor starts to execute instructions so as to configure a plurality of logic units in the MTPMIC through inscribing by the standard bus.

Description

technical field [0001] The content of the present invention relates to the technical field of general power management integrated circuits. Background technique [0002] There are many types of microcontroller ICs available for power conversion and power control applications. Existing microcontrollers usually include a processor with I / O terminals, simple I / O functions, or an analog-to-digital converter (ADC) and / or a digital-to-analog converter (DAC). To use such a microcontroller in a total power control system, some kind of power supply is generally required to provide the voltage so that the power can be used or converted under the control of the microcontroller. The microcontroller's own circuitry must also be powered by DC voltage. Typically the microcontroller is powered by a different DC voltage than the other blocks in the system. The design of a power supply or power pack is therefore usually part of the overall microcontroller control system design task. The p...
