Problems solved by technology

Therefore, when better configurable flexibility is required, or more bits are required, and / or the number of power modules 14 on a chip is increased, the result is a significant increase in the signal lines of the bus structure
[0004] In addition to the lack of flexibility, it is very difficult and risky to increase the design of a given conventional power management IC, especially when the number of required functions is greatly increased.

Abstract

The invention discloses an extensible and programmable power management integrated circuit system comprising a master control module and various slave modules which comprise a power supply function, a battery management function and an analog and digital input / output function. The master control module writes data to configuration registers of the slave modules by a communication network to configure the slave modules. Each module comprises various configuration registers for determining module operation and parameter characteristics. The modules are configured to response proper signals on a configurable interconnecting network to realize programmability.

Description

technical field [0001] The invention relates to a power integrated circuit, in particular to an expandable and programmable power management integrated circuit system. Background technique [0002] Power integrated circuits (ICs), especially circuitry that uses multiple voltages, are becoming increasingly complex, with many different features and configurations. State-of-the-art power management ICs, such as the DA9011 / 9030 / 9031 designed by Dialog Semiconductor, Inc. (Irvine, CA) and the MAX1586A designed by Maxim Integrated Products Inc. (Sunnyvale, CA), include a variety of output voltage adjustable However, these power management ICs are basically fixed in design and developed for a specific, limited range of power supply applications. For example, figure 1 It is a power management integrated circuit 11 in the prior art, and the main controller 12 in the power management integrated circuit 11 controls the power module through a parallel configuration bus driven by confi...
