How telematics is evolving with the connected car
The embedded systems that control vehicle tracking grow more sophisticated by the day. Hope Bovenzi, Texas Instruments Inc. The phrase “car of the future” often invokes thoughts about autonomous driving. But it is fair to also consider what it will be like as a passenger once our driving habits change. With free hands and relaxed […]
Galvanic isolation for electric vehicle systems
High voltages and high currents circulating in EVs make the fundamentals of electrical isolation techniques an important topic. Ross Sabolcik, Silicon Labs AS automotive designs move toward electrification, high-wattage power electronics become critical to new electronic drivetrain and battery systems. In these applications, digital controllers safely interface with the high-voltage systems of modern electric vehicles […]
Primary lithium-manganese-dioxide cylindrical cell features long-term reliability
A high safety and energy density cell, the CR-AG offers important features within the meter market, particularly a long lifespan. This technology replaces thionyl chloride as standard battery. This cell utilizes Manganese-based cathode material to deliver better temperature tolerance so it can operate in harsh environments. For the CR-AG, features include: • High current pulse […]
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 […]
New 1.2-kV IGBTs provide better efficiency
Infineon Technologies AG is launching a new 1200 V IGBT generation TRENCHSTOP IGBT6. It is the first discrete IGBT duopack on the market manufactured on 12-inch wafer size. The new IGBT technology is designed to fulfill the increasing customer requirements for high efficiency and high power density. The product family was optimized for use in […]
Here’s what happens when lithium-ion batteries are drastically overcharged
Lithium batteries have a high energy density so they can store a lot of energy in a small volume. But they can go up in smoke when bad things happen. Recently we recorded a short video to show what can happen during one of those bad things – overcharging. Excessive charging can bring on thermal […]
Dual-input boost-buck charging ICs support USB Power Delivery spec
A growing number of portable devices, including notebook PCs, are adopting the USB Type-C PD standard that can charge up to 100W, providing a common charging platform. At the same time wireless charging is gaining traction, increasing the demand to support both charging methods. However, in order to deliver a wide power supply range required […]
Techargeable battery in SMD technology provides 100 µAh at 1.4 V
TDK Corporation presents CeraCharge – the first solid-state rechargeable battery in SMD technology. Depending on requirements, the number of charge/discharge cycles this battery is able to perform ranges from several dozens to up to 1000. With its compact EIA 1812 package (4.5 x 3.2 x 1.1 mm) it offers a capacity of 100 µAh at […]
