· Smart Battery Backup for Uninterrupted Energy Part 2: BBU Microcontroller Functions and Operations

AbstractThe Open Compute Project (OCP), a nonprofit organization that exchanges data center product designs and best practices across businesses, recently published its Open Rack Version 3 (ORV3) specification. The most significant change in the specification is that the design is now migrating from a 12 V to a 48 V architecture. This is Part 2 of a five-part series highlighting Analog Devices’ reference design for the battery backup unit (BBU). The first part, “Smart Battery Backup for Uninterrupted Energy Part 1: Electrical and Mechanical Design”, discusses the BBU’s electrical and mechanical design considerations. Part 2 goes into further detail about the main microcontroller’s software, which is responsible for guaranteeing the smooth functioning of processes, hence ensuring the BBU’s high efficiency and capacity. Hardware and software must collaborate smoothly to deliver system-level solutions that meet the required specifications.IntroductionI...
