TPS7B86-Q1 Automotive LDO Linear Regulator

Posted on 17 March, 202217 March, 2022 by mixos

Texas Instruments’ adjustable regulator features power-good and is designed for powering always-on components in standby systems

Texas Instruments’ TPS7B86-Q1 is a low-dropout (LDO) linear regulator that is designed to connect to the battery in automotive applications. The device has an input voltage range extending to 40 V, which allows the device to withstand transients (such as load dumps) that are anticipated in automotive systems. With a 17 µA quiescent current at light loads, the regulator is an optimal solution for powering always-on components such as microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems.

The TPS7B86-Q1 has a state-of-the-art transient response that allows the output to quickly react to changes in load or line such as during cold-crank conditions. Additionally, the device has a novel architecture that minimizes output overshoot when recovering from dropout. During normal operation, the device has a tight DC accuracy of ±0.85% overline, overload, and overtemperature. The power-good delay can be adjusted by external components, allowing the delay time to be configured to fit application-specific systems. The TPS7B86-Q1 is available in thermally conductive packaging to allow the device components to efficiently transfer heat to the circuit board.

Instrumems Launches Into Flow Sensor Market With a Breakthrough Multi-sense Solution

Posted on 16 March, 202216 March, 2022 by mixos

Instrumems announced its formal entry into the flow sensor market with a breakthrough solution that offers multi-sense capabilities. The company is an innovative spin-off of Princeton University research developed by Professor Marcus Hultmark and Dr. Gilad Arwatz. Instrumems was founded to advance flow sensing capabilities and broaden adoption into more markets such as medical, IoT, and industrial applications. Instrumems’ product is a multi-sense solution that is the first-and-only to measure accurate flow and temperature, including very low flow, using a single sensor. The company is also expanding capabilities of the physical sensor by using real-time edge computing with advanced algorithms.

Instrumems’ platform is ideal for low-power applications that require real-time sensing in respiratory devices, such as CPAP machines, smart inhalers, and ventilators. Its multi-sense solution is also optimal for thermal management and instrumentation that requires precise flow measurement. Instrumems plans to announce expanded support for additional sensing parameters, such as bubble detection and gas detection.

The flow sensor market is estimated to be approximately $7.5 billion. Demand for airflow sensors is growing across industrial automation and end-user industries, including automotive, data centers, healthcare, medical devices, building automation, food and beverage, and more.

Instrumems’ vision is to bring smart sensing solutions to any device by digitizing data and providing real-time flow sensor visibility and control in areas previously impossible. Products that require flow sensors face many constraints, including form factor, battery life, cost, speed, and sensor accuracy. Today’s flow sensors are exorbitant and bulky, making them uneconomical and inadequate to adopt into consumer products or high-volume applications.

“There’s no other combined temperature and flow sensor in the market today that is as small, low power, fast, and economical as Instrumems’ multi-sense flow solution. Our sensing technology opens the door for a multitude of industries to integrate cutting-edge flow sensors into places previously unworkable due to cost, accuracy, and form factor,” said Gilad Arwatz, Instrumems’ founder and CEO. “Our innovative sensing technology enables customers to modernize, miniaturize, or reinvent their products to be more competitive and aesthetically appealing.”

Instrumems executive team brings expertise in several areas, including flow control, high-precision nano sensors, fluid mechanics, and microelectronics design and development. The executive team includes CEO Gilad Arwatz, who holds a Ph.D. in Mechanical and Aerospace Engineering from Princeton University. Gilad is a serial entrepreneur, having founded other startups in IoT, smart packaging, and AdTech. Vice President of Operations, Ashish Shah, is responsible for developing a high-volume supply chain and project management. Sun Choi serves as Vice President of Business Development and is responsible for expanding into new markets. Instrumems has raised $4 million in seed funding from IP Group and PeopleFund.

Instrumems has an evaluation kit available to demonstrate its flow and temperature sensing and can quickly customize the sensor’s packaging to fit a range of applications. Interested parties can contact info@instrumems.com

New R&S LCX strengthens Rohde & Schwarz portfolio for high performance impedance measurements

Posted on 15 March, 2022 by mixos

With a completely new family of high performance LCR meters, the frequency range of impedance measurements provided by Rohde & Schwarz test equipment is dramatically extended to cover AC components operating from 4 Hz to 10 MHz, supporting all practical applications.

The R&S LCX family of LCR meters serves all established impedance measurements plus specialized measurements for selected component types and provides both, the high accuracy required in R&D, and the high speed needed in production test and quality assurance.

Rohde & Schwarz launches its new LCR meter family of high-performance general-purpose impedance testers covering a wide range of applications. With its supported frequency range from 4 Hz to 10 MHz, the R&S LCX is suitable not only for the vast majority of devices operating at conventional 50 or 60 Hz domestic power frequencies or 400 Hz for aircraft but also for everything from low-frequency seismic sensors to high power communication circuits operating at several Megahertz.

For engineers selecting suitable capacitors, inductances, resistors, and analog filters to match the device application, the R&S LCX models provide high precision impedance values with market-leading accuracy. Equally, higher speed measurements at production-use accuracy for quality control and monitoring are also supported. All the essential software and hardware required for production environments is available, including remote control and result logging, as well as rack mounting for the instrument, and a full range of test fixtures for handling components.

The auto-balancing bridge technology used by the R&S LCX supports conventional impedance measurements by measuring the AC voltage and current for the device under test, including the phase shift. This is then used to calculate complex impedance at any given operational point. As a general purpose LCR meter, the R&S LCX covers many applications, such as the measurement of equivalent series resistance (ESR) and equivalent series inductance (ESL) of electrolytic capacitors and DC-link capacitors. Furthermore, users can test transformers and measure DC resistance in addition to the full range of impedance measurements. To investigate components with impedance values varying at different frequencies and levels, option R&S LCX-K106 supports dynamic impedance measurements with the frequency, voltage or current as the swept parameter.

The R&S LCX family is launched with two models; the R&S LCX100 covers a frequency range from 4 Hz to 300 kHz, the R&S LCX200 a basic frequency range from 4 Hz to 500 kHz with options to cover all frequencies up to 10 MHz. Both models feature a large capacitive touchscreen and virtual keyboard to support tap-and-test for all main measurements. Alternatively, voltage, current, and frequency values can be set using the rotary knob. Less frequently used functions are menu-operated. Settings, results, and statistics can be displayed on the screen or output for automated post-processing. Up to four measurements can be selected and plotted versus time, with minimum and maximum values included in the display for at-a-glance pass/fail analysis.

For investigating impedance in a wider range of materials, the MFIA impedance analyzer from Zurich Instruments AG, a subsidiary of Rohde & Schwarz, complements the R&S LCX perfectly. With the MFIA researchers can characterize semi-conductors or undertake material research into materials including dielectrics, piezoelectrics, ceramics and composites, as well as tissue impedance analysis, cell growth, food research, microfluidics, and wearable sensors.

The R&S LCX family of LCR meters is part of the R&S Essentials portfolio and is now available from Rohde & Schwarz and selected distribution partners.
