Application Notes
Today’s consumers are incredibly comfortable using technology. As a result, we find an increase demand for digital consumer electronic (CE) products in the market today. The personal and mobile device market is undergoing a rapid change as the distinction blurs among mobile phones, personal entertainment devices, and ultra-mobile PCs.
As more digital content becomes available, consumers demand new and improved ways to access this content via wired and wireless technologies. And, in an increasingly portable world, consumers are demanding ways in which to take their digital content with them, wherever they go, whenever they go. Portable CE device designers are being challenged to design products that are able to integrate various features, and yet still remain light in weight, compact, and low in price.
This presents many tough challenges in portable CE devices circuitry design, one of which is power management. This application note describes how the Keysight Technologies, Inc. U2722A USB modular source measure unit (SMU) can act as a battery emulator to help you discover more about your portable CE devices’ chargers, particularly for devices with low current consumptions such as Bluetooth® headsets.
