Supercapacitor backup power management module for 2.9 to 5.5-V supply rails
Analog Devices announces the Power by Linear LTC4041, a complete supercapacitor backup power management system for 2.9V to 5.5V supply rails that must be kept active during a main power failure. Supercapacitors have higher power density than batteries, making them ideal for systems requiring high peak power backup for short periods of time. View the LTC4041 product […]
Dual-mode power monitoring IC includes power calculations and event monitoring
In systems that use both AC and DC power, the implementation of dual-mode power monitoring traditionally requires multiple ICs to ensure superior performance and accuracy. Growing applications such as solar inverters, smart lighting and cloud servers often use both modes to maintain safe operation, with AC as the main power source and DC as backup […]
Expansion of high-performance, off-the-shelf, flat and round heat pipes
Advanced Thermal Solutions, Inc. (ATS), announces the expansion of its line of high-performance, off-the-shelf, flat and round heat pipes. The application of heat pipes in the thermal management of electronics continues to grow significantly and ATS high-performance copper heat pipes with grooved or sintered, copper powder wick structures are the perfect solution for cooling a […]
Single-chip power monitor targets FPGA, GPU circuits
Managing and reducing power consumption is crucial in low-voltage, high-power applications such as Field-Programmable Gate Arrays (FPGAs), Graphics Processing Units (GPUs) and embedded computing devices. These devices must first accurately measure power before they can manageit, but precision power measurement solutions are often costly and require multiple ICs or power configurations to measure different rails. […]
High-voltage multi-chemistry synchronous step-down battery charger/power manager includes optional MPPT
Analog Devices announces the Power by Linear LTC4162, a highly integrated, high voltage multi-chemistry synchronous monolithic step-down battery charger and PowerPath manager with onboard telemetry functions and optional maximum power point tracking (MPPT). The LTC4162 efficiently transfers power from a variety of input sources, such as wall adapters, backplanes and solar panels, to charge a Li-Ion/Polymer, […]
The multiport USB-C architecture takes charge
Xunwei Yu and Sungkeun Lim, Renesas Electronics Corporation The USB-C interface is revolutionizing the way we charge our electronics devices. Its USB Type-C connector cable slides right into your smartphone or ultrabook no matter what orientation you use. Physically, the Type-C connector is both bidirectional (either end of the cable can be inserted into either […]
How USB Type-C connectors hold the key to maximizing data speeds and power delivery
Bruce Rose, CUI The new USB Type-C connector should become a common sight in new laptops and mobile devices over the next couple of years. Smaller and easier to use – allowing plugs to be inserted in either direction – the new mechanical interface has all of the features needed to support the advanced USB electrical […]
PCBs automatically balance two-cell supercap low-voltage systems
Two-Channel printed circuit boards provide production-ready automatic balancing for two-cell supercapacitor low-voltage systems. The SABMB2 offers over-voltage protection and ultra-low power usage for supercapacitors required in industrial controls, remote monitoring, and battery backup applications. Developed by Advanced Linear Devices Inc., the PCB balances leakage current, manages over-voltage and dissipates zero power. Each SABMB2 balances two […]
