Power Reduction Modes On many microcontrollers (MCU), there will be a selection of low-power modes to choose from. Some may be more appealing than others, but careful consideration must be made on power consumption sources and the speed at which modules may resume operation. Do note that not all of these power reduction modes are […]
Power Supply A consistent but highly efficient voltage regulator is crucial in power design. While there are many regulators to choose from, each comes with its own set of tradeoffs that must be accounted for. Linear Regulators Linear regulators may appear to be a low cost and cheap solution at first glance but are flawed […]
Battery Chemistries When searching for a battery for an application, a myriad of choices are at your feet. One of the first choices is battery chemistry. The question you must ask is, after consideration of your challenging requirements, what option is the best for my specific application? Alkaline Alkaline cells run the mill consumer battery, […]
Low Power Design Overview The bane of any battery-operated device, too much power draw and not enough storage capacity. If designed poorly, creating a device to last as long as the user requires will be a challenge. However, if some ingenuity and unconventional thinking are used, many new possibilities will arise and allow for the […]
Mark Omo will be giving a presentation on Qi Wireless Charging at Microchip Technology’s 2019 Worldwide MASTERs conference, along with Santosh Bhandarkar from Microchip. Their class is 23104 PC12: Fundamentals of Wireless Power, and if you’ll be at MASTERs this year, you should check it out. To accompany his presentation, Mark developed a spreadsheet that […]
