Port controllers, transceivers, and special dc/dc converters now simplify the task of adding USB Type-C functions. DANIEL LEIH, MICROCHIP TECHNOLOGY INC. CONSIDER THE VIRTUES of the USB-C connector. In addition to its 10 Gbit/sec (Gbps) bandwidth and Alt Mode video capabilities, two attributes, in particular, make this form factor incredibly valuable: a reversible plug and […]
Maximizing efficiency and safety with rechargeable batteries
Some rechargeable lithium battery chemistries need more TLC than others when it comes to safety precautions. TOM BLAHA, MEMORY PROTECTION DEVICES RECHARGEABLE BATTERY TECHNOLOGY has come a long way, continually boosting performance with fewer annoying memory effects that severely limited the useful operating life of earlier generation cells. The most common rechargeable battery chemistries commercially […]
Nanopower PMIC maximizes battery life, minimizes board area
Dialog Semiconductor plc announced its first fully-integrated nanopower PMICs for IoT applications, the DA9070 and DA9073. The new, more powerful PMICs build on the success of Dialog’s first nanopower offerings, further highlighting how Dialog has pushed the boundaries of its PMIC technology to improve low-power IoT applications. Today’s ‘always-on’ IoT devices such as fitness trackers, […]
Intelligent Power Modules for on-board charging 40% smaller than discrete options
ON Semiconductor’s new automotive FAM65xxxx Intelligent Power Modules (IPMs) offer class-leading power density and improve overall performance in on-board charging (OBC) and other high-voltage DC-DC conversion applications for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). The FAM65xxx APM16-packaged devices offer a fully-featured, integrated solution that eases design-in for automotive customers with one device outline covering H-Bridge, […]
Power Integrated Modules target 30KW & 50KW inverters
ON Semiconductor has launched new Power Modules that offer excellent energy efficiency, reliability and performance in highly integrated and compact packaging, adding to the company’s already robust portfolio of power semiconductor devices. Traditionally, power stages in applications such as solar power inverters, UPS inverter stages and industrial variable frequency drives (VFD) have been built from […]
Power-supply overvoltage protection, Part 1: Crowbars
Engineers who deal with power supplies (as most eventually do) often see the circuit-protection terms “crowbar” and “clamp.” No, there are no references to items purchased at the local hardware store, but they are essential “hardware” elements, meaning autonomous circuit components and functions with no related software. They are used to provide protection to a […]
USB Type-C and USB Power Delivery controllers source up to 200 W
Texas Instruments introduced two new USB Type-C and USB Power Delivery (PD) controllers, with fully integrated power paths to simplify designs, minimize solution size and speed time to market. The TPS65987D and TPS65988 offer system designers the industry’s highest level of integration which can reduce design complexity and overall cost. The devices are the industry’s […]
Super-low-voltage supervisors feature ±0.5% reset threshold accuracy for ASIC, FPGA, DSP, MCU, MPU architectures
Analog Devices announces the Power by Linear LTC2962-LTC2964 family of highly accurate 4-channel voltage supervisors for increased system voltage margin and enhanced reliability. ASIC, FPGA, DSP, MCU and MPU architectures that operate from supplies as low as 1V cannot utilize traditional 1%-2% accurate voltage supervisors without shedding valuable system voltage margin and shrinking the remaining load […]
HVDC power shelf accepts 240 to 380-Vdc inputs
Bel Power Solutions and Protection announces the SPSPFE3-07 power shelf, which provides rectification, system management and power distribution from HVDC mains (240/380Vdc) power into a main output of 12 VDC for powering intermediate bus architectures up to 15kW (5+1) in high performance servers, routers and network switches. Each SPSPFE3-07 shelf can be configured with up […]
Battery fuel-gauge ICs boast 5.2μA quiescent current
Designers of lithium-ion (Li-ion) battery-powered mobile and portable devices such as wearables, electric bicycles, power tools and internet of things (IoT) products can improve the end-user experience by extending run-time and delivering the most accurate battery state-of-charge (SOC) data in the industry with the MAX17262 single-cell and MAX17263 single-/multi-cell fuel-gauge ICs from Maxim Integrated Products, Inc. The MAX17262 features […]
