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 […]
Highly integrated PMIC optimized for NXP i.MX 8M application processors
ROHM today announced the availability of a programmable system power management IC (PMIC) optimized for NXP Semiconductors’ i.MX 8M family of applications processors that excels in processing audio, video, and graphics in a wide range of applications, from home audio/video to industrial automation and mobile computing. BD71837MWV integrates all power rails required by i.MX 8M processors and system […]
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 […]
Powering battery-free low-power sensors, embedded circuits, wireless devices
Smart suitcases can be wirelessly tracked, they can weigh themselves, and their locks can be opened and closed by remote control. But all such luggage now depends on batteries, which run down and can also, in some cases, explode. The Face Companies of Norfolk, Virginia, announced today that they’ve solved the problem that’s been inhibiting […]
Multiphase PMICs provide up to 20A of output current, 94 percent peak efficiency
Renesas Electronics Corporation announced three programmable power management ICs (PMICs): the ISL91302B, ISL91301A, and ISL91301B PMICs. The PMICs also deliver power to artificial intelligence (AI) processors, FPGAs, and industrial microprocessors (MPUs), and they are ideal for powering the supply rails in solid-state drives (SSDs), optical transceivers, and a wide range of consumer, industrial and networking […]
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 […]
Power system manager combines digital measurements, PMBus interface computation
Analog Devices announces the Power by Linear LTC2972, a 2-channel power system manager, featuring current, power and energy monitoring of the intermediate bus input to point-of-load (POL) converters. Monitoring circuit board power and energy use is a prerequisite for managing, optimizing and reducing their consumption in order to lower server rack and data center cooling and […]
