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 […]
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 […]
ICs comply with USB Power Delivery 3.0 standards for fast charging of smartphones, tablets, and notebooks
Power Integrations announced that a range of adapter designs based on Power Integrations’ InnoSwitch3-Pro and InnoSwitch3-CP ICs have achieved compliance with USB Power Delivery (PD) 3.0 standards. During a recent workshop in Portland, Oregon, nine adapter designs featuring InnoSwitch3 devices – including several designs submitted by leading power-supply manufacturers – successfully completed USB PD 3.0 […]
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 […]
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, […]
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 […]
