AN78646 - Integrated Power Manager using PSoC® 1: Introduction to Power Management Computi... #psoc #cypresssemi
AN78646 describes power management - a critical component of System Management Control (SMC) for computing and communication systems - and explains key concepts of power management such as voltage sequencing, fault detection, voltage and current monitoring, real-time trimming, and I2C host communication. The associated example project delivers a fully integrated power management system solution using a CY8C28645 PSoC® 1 device. Introduction to Power Management Computing and communication systems are complex and are made up of multiple subsystems. Each subsystem can have its own voltage domain, also known as a power rail. Each of the power rails needs to be powered up and monitored individually, thus creating a need for power management activity. Because this activity is a health indicator of the system, it cannot be incorporated in any of the subsystems. For this reason, a...
