Industry Experts Assess Power’s Frontiers
The future of the grid is spelled IEC 61850, and many pieces of the infrastructure are available. And, greater efficiency and innovation are still on the way for the common ac-dc and dc-dc digital power supply …
The Basics Of PMBus Design
The PMBus standard for digital power management is the result of collaboration between power supply and semiconductor companies …
Design Touchscreen-Based Handheld Systems For Low Power Consumption
Keep an eye on how your system operates in four key modes—active power, sleep, deep sleep, and hibernate—to improve power efficiency …
High-Side Switch Provides Overvoltage Protection With Only Four Components
Low-voltage microcontrollers often need to control higher-voltage loads via high-side switching. This simple two-transistor circuit enables that control and provides over-voltage protection.
Multiple Power Supplies Fortify High-Side Gate Control
A switching power supply was devised to ensure high-side FET gate control, particularly in light of a wildly floating high-side rail. The design’s “VeeDrive” delivers a sharp and muscular square-wave that’s robust enough to drive several charge pumps.
Test Setup Checks Transistors’ hFEs When Tight Control Is Important
This circuit uses pulsed current to check transistor hFE on an oscilloscope. The circuit creates the biasing conditions specified by the transistor’s manufacturer.
Add Short-Circuit Protection, Diagnostics To Automotive High-Side/Low-Side Driver
Smart switches for automotive applications are costly, may not be readily available for 24-V operation, and often come in unneeded dual and quad configurations. By adding a few standard, low-cost components to a basic driver, you can make a smarter one which includes short-circuit protection and built-in diagnostics.
