The Challenge

Power management is the set of sources, rails, switches and resets that keeps every block inside its limits in the modes you intend, and in the modes that happen anyway: a plug inserted, a cell sagging during a radio burst, charge and load at once, a brown-out halfway through a write. A regulator symbol beside the microcontroller is not that set.

Start from the source you will ship and from a load profile written in modes. Name each rail, who may be awake, the order in which rails become valid, and what the firmware must refuse to do until they are.

Description

This Insights guide explains Power Management for founders and engineering teams building hardware that must be manufactured, tested, and handed off. Start from the source you will ship and from a load profile written in modes. Name each rail, who may be awake, the order in which rails become valid, and what the firmware must refuse to do until they are. It also covers start from the source, then draw modes; choose the converter from the profile, not from a habit; reset, brown-out, and the heavy event.

The Outcome

Every source the user or the factory can connect is named, including 'debug only' ports. Two sources at once have a winner, and the loser cannot back-feed. Each mode has a column: which blocks are powered, and which are merely 'off'.
