5.5v over-voltage solution uses OPMs
Until now, portable devices supplied by USB, Li-ion or NiMH batteries with voltage levels up to 5.5 V could not use standard process devices, such as 3.3 V CMOS I/O transistors. This lead fabless semiconductor companies to use expensive alternatives, such as external regulators or expensive process options, including HV/BCD processes.
LED matrix manager controls 96 high-brightness LEDs
Claimed to be the industry’s first fully integrated high-brightness LED matrix manager IC for adaptive automotive headlight systems, Texas Instruments has announced the TPS92661-Q1. This enables automobile manufacturers to create innovative LED headlamps that vary beam patterns and intensity dynamically for optimum roadway illumination and enhanced driver safety.
Motor drive power analysis software upgrades oscilloscopes
Teledyne LeCroy has introduced three-phase Motor Drive Power Analyser software for its HDO8000 oscilloscopes. The HDO8000 mixed-signal oscilloscopes, with 8 input channels, 12-bit resolution, and up to 1 GHz bandwidth, enable motor drive embedded control and power section debug.
Li-ion battery charger extends life of eCall systems
Designed to extend the life of Li-ion batteries in automotive emergency call (eCall) systems, a single-cell battery charger has been introduced by Intersil. The ISL78692's leakage current dissipation of 3μA and charging voltage of 4.1V enables a backup battery to remain charged and be used for a longer period of time.
RF Energy Alliance unveiled at European Microwave Week
NXP Semiconductor is amongst a group of companies that have come together to form the RF Energy Alliance announced at European Microwave Week. Joining NXP in the launch are EGO Elektro-Gerätebau, Huber+Suhner, ITW, Rogers Corporation and Whirlpool R&D (an affiliate company of Whirlpool Corporation).
Leveraging SiC properties to improve power switches
As the industry pushes forward to realise SiC’s full potential, Jochen Hüskens, Rohm Semiconductor, argues that the next generation of SiC power devices is well-positioned to enable new high-volume applications such as EVs and solid state transformers.
Solid-state RF power transistors modernise microwave ovens
The 250WMHT1003N and 350WMHT1002N RF power transistors, designed for consumer and commercial microwave oven appliance OEMs, have been released by Freescale Semiconductor. While theMHT1003N provides58% power added efficiency for 2.45GHz microwave oven applications, theMHT1002N provides63% for 915MHz microwave applications.
Cloud-scale switch series delivers 3.2Tb/s
Designed for cloud-scale data centres, the StrataXGS Tomahawk switch series has been released by Broadcom. Delivering 3.2Tb/s switching capacity, the series is claimed to be the industry's highest performing Ethernet switch. The switch series integrates more than 7bn transistors, enabling the transformation of next-gen cloud fabrics to all-25Gb/s per-lane interconnect and increasing link performance by 2.5 times.
