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, […]
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 […]
High-voltage contactors handle up to 500 A
TDK Corporation has extended its HVC series of high-voltage contactors with the new HVC300 and HVC500 types with current capabilities of 300 A and 500 A, respectively. The new contactors can switch high voltages of up to 900 V DC, while types for 1200 V DC are available on request. Their gas-filled switching chamber ensures that […]
Ultra-low-power switch features “Deep Sleep” function to hold battery charge
GLF Integrated Power introduces the GLF76321 IQSmart IC load switch with “Deep Sleep” power conservation mode. While in this mode, the device operates with a typical standby current (ISD) of just 7nA – which is negligible compared to the typical self-discharge of Li-ion batteries. By virtually disconnecting the battery during shipment and storage, the GLF76321 enables products […]
A low-dropout CC/CV 12V lead-acid battery charger with auto trickle-charge
by Crutschow, Electro-Tech-Online community member For the best charging of lead-acid batteries a three-step technique is often used, consisting of an initial constant-current charge, then a high constant-voltage top-off, and finally a lower constant voltage trickle-charge. But a simpler two-step technique can also work fairly well, which is to start with a constant-current until the […]
Ultra-Low-Power battery protection IC targets wearables and small IoT devices
The GLF73510 IQSmart IC is designed to virtually eliminate wearable and IoT device battery discharge during standby or deep-sleep operation. The GLF73510 consumes an industry-leading ultra-low leakage current (ISD) of 2 nA (typ.), as much as 1,000 times less than other chips commonly used in this application. Applications for wearable and smaller IoT battery powered […]
High-voltage smart sensor data-acquisition device targets vehicle lithium-ion battery packs
Automotive OEMs can enhance the safety of their lithium-ion battery packs with robust communications, comprehensive diagnostics, and lower system costs using the MAX17843 12-channel, high-voltage smart sensor data-acquisition device from Maxim Integrated Products, Inc. Electric vehicles (EVs), hybrid EVs, and plug-in hybrids rely on large lithium-ion battery packs filled with hundreds or even thousands of individual battery […]
How to hot plug sequence your BMS cell connections
By Robert Grist, Intersil, a Renesas Company Lithium-ion (Li-ion) batteries are used in a wide variety of portable system applications, including vacuum cleaners, lawn equipment, handheld power tools, e-bikes, and energy storage systems. Li-ion batteries are smaller, weigh less, and deliver longer battery life than other battery chemistries, but require monitoring and protection for safe […]
Improve automobile battery life with the right chemistry
by Theju Bernard, Intersil, a Renesas Company The automotive industry is quickly moving toward more electrification. The deployment of start-stop systems, emergency call (eCall) telematics, and hybrid vehicles is fueling the need for advanced battery management systems that not only charge the battery in a safe manner but also prolong its useful life. There are […]
Power monitoring IC boosts software power measurement accuracy to 99% in Windows 10 devices
A precision power and energy monitoring chip works in conjunction with a software driver that is fully compatible with the Energy Estimation Engine (E3) built into the Windows 10 operating system to provide 99% accuracy on all Windows 10 devices that have batteries. Developed by Microchip Technology, the PAC1934 and Windows 10 driver can improve […]
