Pressure sensor is sensitive for extended temperatures

Tue, May 14, 2019

A ceramic port is included in the design of the Bourns Model BPS140 pressure sensor to enhance its compatibility with certain harsh media, explains the company.

The pressure sensor is added to Bourns’environmental sensors. It is based on microelectromechanical systems (MEMS) technology, which provides extremely accurate condition readings in a miniature package size. Designed to deliver high sensitivity/accuracy and long-term reliability, the BPS140 pressure sensors offer extended temperature capability and certain harsh media compatibility.

Model BPS140 is robust with a structure that is capable of handling high pressure ranges (15 to 500 PSI) even at high temperatures. This rugged structure is combined with rear pressure measurement that minimises the number of media-sensitive wetted materials. The purpose of this sensing design is to ensure the measured media only touches the back of the measurement element, explains Bourns.

The structure enhances sensor accuracy because all electronic components and other sensitive surfaces are isolated from the media, explains Bourns. In addition, by reducing the number of wetted materials, the media sensitivity of the sensor is effectively decreased, adds the company.

Bourns’ latest sensor family offers stable performance over the product’s lifespan, and the ability to work with a wide range of pressures offering a total error band of 2.5 per cent full scale over a temperature range of –40 to +150 degrees C (six sigma process), and a lifetime drift of 0.5 per cent full scale. These features make the BPS140 pressure sensor particularly suitable for a range of industrial, energy, heavy equipment, building and home control and medium/low risk medical designs.

Bourns¨ Model BPS140 pressure sensors are available now, and are RoHS** compliant. Bourns also offers port configuration and calibration customisation.

Bourns manufactures and supplies position and speed sensors, circuit protection solutions, magnetic components, microelectronic modules, panel controls and resistive products.

The company is headquartered in Riverside, California, USA, and serves a broad range of markets, including automotive, industrial, consumer, communications, medical (low/medium risk), audio and various other

Programmable PMIC increases ADAS reliability

Tue, May 14, 2019

Space can be saved in advanced driver assistance systems (ADAS) and reliability increased with the L5965 power management integrated circuit (PMIC), says ST Microelectronics.

The seven-output automotive PMIC enables more compact and reliable electronic control units leveraging direct operation from battery voltage with register-programmable output voltages and sequencing and integrated functional-safety mechanisms, explains ST Microelectronics.

With seven regulated outputs, a single L5965 can power an entire camera- or radar-based driver-assistance system including the sensors, memory ICs, processor, and CAN interface circuitry. One-time programmable (OTP) cells for setting the output voltages and sequencing allow the user to configure the PMIC for a variety of ADAS and other in-car applications.

The L5965 can operate directly from the vehicle battery which allows its use without a pre-regulator. Its register-programmable outputs also eliminate voltage setting resistors, and the on-chip regulators can be used without external compensation circuitry. The PMIC reduces both footprint and bill of materials. The savings in external components also increase system reliability and enhance accuracy, explains ST Microelectronics, by eliminating fluctuation due to environmental effects on external components.

The integrated functional-safety features are designed in compliance with ISO 26262 and enable systems to fulfil Automotive Safety Integrity Level (ASIL) requirements up to ASIL-D. The mechanisms include a failure status pin, voltage monitors, ground-loss comparators, analogue and digital built in self-test (BIST), and temperature monitors.

Samples of the L5965 are available now in a small and low-cost 7.0 x 7.0mm QFN48 package that requires no heatsink.

Ray tracing technology uses light modelling for realism

Mon, May 13, 2019

PowerVR Ray Tracing technology is now available for licensing from Imagination Technologies. The intellectual property (IP) enables realistic 3D graphics for any market, says the company.

PowerVR Ray Tracing technology uses light modelling techniques for realistic image rendering that can be integrated into graphics processing units (GPUs) across mobile, automotive, server and other markets.

The PowerVR Ray Tracing architecture is an efficient method of processing billions of rays per second (Gigarays, or GRays). According to Imagination, it makes it realistic for SoC manufacturers to offer ray tracing capable hardware within a range of power and thermal envelopes. The technology is particularly suited to adding realistic ray traced light, shadow and transparency capabilities to traditional GPUs and can even be used to create full ray tracing solutions.

Ray tracing available today is used for PC and consoles but does not offer the efficiency required for mobile, augmented reality (AR) or automotive applications, explains Imagination. Its approach is to design the architecture from the ground up for power efficiency with the ability to scale from battery-powered embedded designs to large-scale server farms.

“We are confident that ray tracing is going to happen across many applications, and in a 5G world it is likely to be very disruptive. Our ray tracing architecture matches much larger and less power efficient solutions gigaray for gigaray,” said Nigel Leeder, executive vice president, PowerVR.

Imagination PowerVR Ray Tracing technology available for licensing today includes patents, architecture, GPU integration references and standards-based application program interface (API) support for easy application integration.

Imagination holds over 220 patents and applications based on its ray tracing technology.

Imagination’s PowerVR Ray Tracing IP technology is available now for licensing. It can be used in conjunction with a wide range of GPU architectures, including Imaginations’ PowerVR graphics cores.

Imagination offers a broad range of silicon IP which includes the key processing blocks needed to create the SoCs that power all mobile, consumer and embedded electronics. Its software IP, infrastructure technologies and system solutions enable its customers to get to market quickly with complete and highly differentiated SoC platforms. Imagination’s licensees include many of the world’s leading semiconductor manufacturers, network operators and OEMs/ODMs who are creating some of the world’s most iconic products.
