Voltage rail splitters and virtual grounds for batteries and PFCs
Rail splitters are usually associated with battery-powered devices, but that’s not always the case. There are several definitions of a “rail splitter,” sometimes referred to as a “virtual ground” or “pseudo ground.” The most common meaning is creating a new “0V” reference point, usually the mid-point Vin/2 of a single supply voltage such as a […]
Don’t rush to choose rechargeable batteries…at least, not yet
Using energy harvesting and a rechargeable battery to power a remote wireless IoT node seems like an obvious and straightforward solution, but there are some unique aspects to consider. Don’t get me wrong: I really like rechargeable batteries; in fact, I like them a lot. Whether based on lead-acid, nickel-cadmium, lithium-ion, or other chemistry, our […]
Battery charger IC handles low-voltage charging of wearables, compact IoT devices
The BD71631QWZ battery charger IC from Rohm Semiconductor is designed to provide low-voltage charging of wearables (e.g., wireless ear buds) and thin, compact IoT devices (e.g., smart displays) powered by rechargeable batteries. In recent years, the need for safer, higher density rechargeable batteries has led to the development of new battery types. This includes all-solid […]
Lightweight dc/dc converters target fuel cell applications
With its new DCHV320 DC-DC converter, BrightLoop Converters is aiming to provide the best off-the-shelf DC-DC conversion solution to fuel cell vehicles by focusing on extreme power density and versatility. In a Fuel Cell Electric Vehicle (FCEV), the fuel cell produces electricity to power the high-voltage batteries needed to run the electric motor. However, fuel […]
Clearing up confusion about tracking multiple current levels
Multichannel power monitors help simplify battery-based systems employing multiple current sensors. Mitch Polonsky • Microchip Technology Inc. Designers of power systems can be forgiven for having some confusion about power monitors. Some of them may even be using a multichannel power monitor without knowing it. That’s because, regrettably, several different phrases are used to refer […]

Talk of EV fires still smolders
Leland Teschler • Executive Editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler The latest figures from the National Fire Protection Association show that only about 20% of all vehicle fires arise from problems in the vehicle electrical system—most fires have something to do with the fuel system. Seeing as electric vehicles will do away with problematic petrol, […]
