Accurate Fuel Gauging Through State-of-Charge Measurement

On December 4, 2019 in All, Power by Robert Huntley

Determining a battery’s state-of-charge using voltage alone is not an accurate method. By combining the open-circuit voltage, current flow, operating temperature, battery age, and discharge rate into a single algorithm, the Maxim MAX1730x series delivers a highly accurate fuel gauge for your product.

Solving BLDC Controller Design Challenges with the Qorvo PAC5556

On November 26, 2019 in All, Industrial, Motor Control, Power by Robert Huntley

Brushless DC motors have become a popular choice for use in a wide range of consumer and industrial appliances. Building a controller for a BLDC requires several key functions, all of which are combined in the single-package Qorvo PAC5556 Power Application Controller® (PAC™).

48V Electrical Systems Shift into High Gear

On November 18, 2019 in All, Automotive, Power by TDK

The development of so-called “micro hybrid” and “mild hybrid systems” based on 48V power has shifted into high gear. Learn how versatile automotive 48V electrical systems will reduce CO2 emissions and usher in practical, super-efficient electrical subsystems.

A Lesson from the Wind and the Sun

On October 31, 2019 in All, Power by Paul Golata

Gather round and let me tell you a story about the power of the wind and sun. These are gifts for us to enjoy. ADI is leading the way for humanity to harness their collective power through energy storage systems

Why SiC Devices Are Ideal for Level 3 EV Charging Applications

On September 24, 2019 in All, Power, Wide Bandgap by Robert Huntley

Charging an EV can be a lengthy process, however, Level 3 “fast” DC charging techniques promise much faster charging capabilities that reduce charging times to minutes instead of hours. This efficiency relies on high-speed power conversion, for which new wide-bandgap technologies are well suited.

Achieving a Single Higher Voltage from a Dual-Output DC/DC Converter

On September 10, 2019 in All, Power by Robert Huntley

As applications use more sophisticated devices, the demand for more complex supply voltages increases. One viable approach to meeting the requirement for a higher voltage rail includes the use of a dual-output DC/DC converter. This blog explains how to integrate this type of converter into your designs.

Selecting a No-Opto Flyback DC/DC Converter for Space-Constrained Designs

On August 29, 2019 in All, Power by Robert Huntley

Traditionally, isolated DC/DC flyback converters used an optocoupler or a third transformer winding for line regulation. This led to design complexity, increased cost, and the need for more PCB space. Simplify your design with a no-opto flyback converter IC to regain PCB space and lower your BOM cost.

USB-C Becomes Standard For Power Delivery

On June 12, 2019 in All, Connectors, Power by Robert Huntley

Need to update your product and replace the legacy barrel power connector? Discover how you can transition your device designs using a simple, no-firmware, highly integrated, and USB-IF-certified method from Cypress and Molex.

At 90W, Power over Ethernet Hits the Sweet Spot

On April 1, 2019 in All, Industrial, IoT, Power, Sensors by Barry Manz

The 802.3bt standard lets devices consume more power, which makes it a compelling solution for smart buildings and cities.
