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 […]

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 […]
