Temperature controller operates from -40 to +250°C
A temperature controller that creates a seamless transition between heating and cooling devices, as it serves as the commander of thermoelectric modules, has been introduced by Oven Industries. The 5R7-001 features a bi-directional or unidirectional H-bridge configuration.
Battery monitoring LSI offers 25μA current consumption
LAPIS Semiconductor, a ROHM Group company, has recently announced the development of a 10-cell lithium-ion battery monitoring LSI that provides a current consumption of only 25μA (typ.), the lowest in the industry, making it suitable for battery protection systems in cordless vacuum cleaners, electric tools, and other portable equipment.
Single-output DIN-rail power supplies provide up to 96W
Powersolve has introduced a family of 10 to 96W DIN-rail power supplies designed for installation on DIN rail TS35/7.5 or 15. The PDN10, 20, 40, 60 and 100 series are high efficiency, high reliability power supplies that will operate from a universal 88-264VAC input.
Li-ion battery monitoring LSI delivers a current consumption of 25μA
A 10-cell Li-ion battery monitoring LSI that provides a current consumption of only 25μA, which is claimed to be the lowest in the industry, has been introduced by LAPIS Semiconductor. Suitable applications include battery protection systems in cordless vacuum cleaners, electric tools, and other portable equipment.
The world’s lowest-power energy harvesting PMICs
A family of energy harvesting PMICs that enable tiny, solar-powered wireless sensors for IoT applications has been introduced by Cypress Semiconductor. The new devices are claimed to be the world’s lowest-power, single-chip energy harvesting PMICs, and can be used with solar cells as small as 1cm2.
Zero-drift, low-noise op amp includes on-chip EMI filtering
Analog Devices has introduced the first model in a series of high-voltage, low-noise, zero-drift, precision operational amplifiers that reduce system noise, cost, board space, and development time by providing on-chip EMI filtering and eliminating the need for calibration circuitry. The dual-channel ADA4522-2 op amp operates within a supply voltage range of 4.5-55V and exhibits noise performance that is at least 35% better than its closest c...
FPGAs withstand differential power analysis attacks
Microsemi has announced that its SmartFusion2 SoC FPGAs and IGLOO2 FPGAs have passed certification for resistance to Differential Power Analysis (DPA) in the DPA Countermeasure Validation Programme developed by Rambus Cryptography. This allows Microsemi to use the Cryptography Research trademarked “DPA Lock” security logo under license from the organisation in connection with these products.
1.5A, 15V sync boost regulator offers 95% efficiency
Linear Technology Corporation has announced the LTC3121, a 3MHz current mode, synchronous boost DC/DC converter with integrated output disconnect. Its internal 1.5A switches deliver output voltages as high as 15V from an input voltage range of 1.8V at start-up (0.5V when running) to 5.5V, making it suitable for battery or standard 3.3V and 5V power sources.
Battery charger and power analysis packed into one tool
A new 10-slot battery charger from VOLTCRAFT has been introduced by distributor Conrad Business Supplies. Added to the in-house designed range of power devices, power supplies and accessories is the Charge Manager 2024 which blends the role of battery charger and power analysis tool and features a graphical display to show the charging status of batteries and ensure their optimised use.
Battery forum to discuss Li-ion potential, optimisation & safety
At the 9th Developer Forum Battery Technologies, taking place 3rd to 4th November 2015 at Lindner Park-Hotel Hagenbeck in Hamburg, Germany and organised by Batteryuniversity, participants will acquire information about the latest trends and development potential in the area of lithium-ion batteries, possibilities for optimal utilisation of their capacity and determining the 'state of health', strategies for maximising safety with statio...
