Magnetic speed sensor rejects offsets

Allegro A1667 sense

Allegro MicroSystems’ surface-mount magnetic speed sensor contains a compensating circuit that reduces the detrimental effects of magnet and system offsets. “Digital processing of the analogue signal provides zero-speed performance independent of air gap as well as dynamic adaptation of device performance to the typical operating conditions found in automotive applications, including reduced vibration sensitivity,” said the firm. Called A1667, to comes ...

Microchip extends PIC32 range downwards

PIC32MM

Microchip has created the lowest power and least costly family of PIC32 microcontrollers (MCUs), positioned between the PIC24F XLP and PIC32MX families, and the first PIC32s to have the firm’s ‘core independent’ peripherals. Called PIC32MM, the family is aimed at IoT, consumer, industrial and motor control applications. Key figures are: sleep down to 500nA and a 4x4mm package. The core-independent peripherals selected include: ...

TDK adds to DC-DC converter series

image

TDK Corporation has added two models to the TDK-Lambda i6A series of step-down, non-isolated DC-DC converters. The i6A4W is capable of supplying currents of up to 20A, and the i6AN allows the creation of negative voltages delivering currents up to 8A. Both can be used in conjunction with the previously announced 14A rated i6A series to generate additional system voltages ...

STM32 developers get access to low-layer APIs

STM32 Nucleo

STMicroelectronics has added low-layer application program interface (LL API) software to its STM32 development tool set. This is for experienced designers and will allow them to work with the ARM Cortex-M microcontrollers (MCUs) down to register-level code, to controlling device peripheral and to optimise performance and run-time efficiency. The LL APIs are integrated into the STM32Cube packages with example projects designed ...

GPS chip adds inertial dead-reckoning for car tracking

ublox C93-M8E

u-blox of Switzerland has introduced a GPS receiver that works with inertial sensors to add dead-reckoning navigation when satellites signals are weak or before the receiver has locked-on. It requires an external MEMS inertial sensor and flash memory, and also works with other satellite navigation (GNSS) systems (list below). “EVA-M8E adapts automatically to installations anywhere within a vehicle. Dead-reckoning with ...

Zeolites could make LEDs cheaper and more efficient

image

Researchers from KU Leuven (Belgium), the University of Strasbourg, and CNRS have discovered a new phosphor that could make next-generation fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites. Silver clusters consist of just a few silver atoms and have remarkable optical ...

Ekinops transponder/muxponder line doubles network capacity

image

Ekinops is introducing a flexible rate transponder/muxponder line which allows network operators to double their transport capacity. Using an advanced digital signal processor (DSP) combined with Ekinops’ enhanced T-Chip (transport-on-a-chip) technology to support both DP-QPSK and 16QAM modulation formats on a single line card, Ekinops is able to deliver a low-cost, programmable 400G solution. This can double the capacity of ...

TT Electronics launches SiC power mosfet

image

TT Electronics has launched an SiC power mosfet for high temperature, power efficiency applications with a maximum junction temperature of +225°C. As a result of this operating potential, the package has a higher ambient temperature capability and can therefore be used in applications, including distribution control systems with greater environmental challenges, such as those in close proximity to a combustion engine. ...

White Paper: Panasonic’s infrared array sensor explained

GetFileAttachment

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are adopted with thin film IR absorbers. Many applications are being developed, such as thermography, human detection, night vision and so on. Quantification of this energy allows users to determine the temperature and thermal behaviour ...
