Dual output Hall-effect sensors save space while detecting speed and direction

Thu, Sep 21, 2023

For high voltage, automotive and industrial applications, the AH39xxQ series of Hall-effect sensors provide speed and directional data, said Diodes.

The high-voltage, dual output, automotive-compliant sensors provide accurate speed and directional data or two independent outputs. They are designed for industrial and automotive applications such as detecting rotational and linear speed/direction and determining the angular position of a rotating shaft.

They operate over a wide supply voltage range of 2.7 to 27V to meet automotive battery requirements. They also have a 40V absolute maximum rating, enabling them to safely handle 40V load dumps.

There is also -18V of reverse voltage protection to guard against incorrect battery connections.

For added robustness, the ESD (electrostatic discharge) protection exceeds the automotive norms of 5kV human body model (HBM) and 2kV charge device model (CDM).

Three BOP/BRP (operating/release) options are offered, with typical values of 10/-10, 25/-25 and 75/-75 Gauss and the narrow operating window ensures accurate and reliable switching points, confirmed Diodes.

Dual-channel operation means these sensors can replace two latch switches, reducing both PCB space and overall component costs. Combining chopper-stabilised amplifiers with an advanced Hall plate design mitigates switch point drift, ensuring accurate measurements over a broad temperature range.

The self-diagnostic features make the AH39xxQ sensors suitable for ISO 26262-compliant systems. There is also a safe operating mode which is entered if an error, such as over-temperature or under-voltage lockout, is detected.

The AH39xxQ series Hall-effect sensors from Diodes are AEC-Q100 Grade 0 qualified, manufactured in IATF 16949 certified facilities, and support PPAP (production part approval process) documentation.

They are supplied in TSOT25 packages.

Diodes supplies semiconductor products to the world’s leading companies in the automotive, industrial, computing, consumer electronics, and communications markets. Its product portfolio consists of discrete, analogue and mixed-signal products and packaging technology.

The company has worldwide operations of 32 sites, including engineering, testing, manufacturing.

MAC-PHY devices connect automotive devices with 10BASE-T1S Ethernet

Fri, Sep 15, 2023

A family of LAN8650/1 MAC-PHY devices developed by Microchip Technology can be used to connect low-cost microcontrollers without a built-in Ethernet MAC (media access controller) to a 10BASE-T1S Ethernet network.
In automotive designs, 10BASE-T1S technology makes it possible for low speed devices to connect to a standard Ethernet network, eliminating the need for dedicated communication systems. Expanding its portfolio of automotive-qualified Ethernet solutions, the LAN8650 and LAN8651 MAC-PHYs are qualified for automotive applications. They include a MAC and SPI (serial peripheral interface) to connect devices at the edge of automotive networks.
The built-in MAC and SPI enable designers to connect 8-, 16-, and 32-bit microcontrollers that do not have a built-in Ethernet MAC to 10BASE-T1S SPE (single pair Ethernet) networks. As a result, sensors and actuators that interface between the digital and the real world to become part of an all-Ethernet architecture. Connecting to even the simplest microcontrollers can reduce the overall size and cost of a design, said Microchip.
Matthias Kaestner, corporate vice president of Microchip’s automotive business, commented: “This new technology will connect sensors and actuators in the physical world all the way to the cloud, enabling a seamless Ethernet architecture in vehicles, which in turn reduces development effort and time to market”.

These devices are equipped with time-sensitive networking (TSN) support, which allows for synchronised timing across Ethernet networks. This synchronisation is critical for many automotive applications such as advanced driving assistance systems (ADAS).
The automotive-qualified LAN8650/1 devices comply with AEC-Q100 Grade 1 for enhanced robustness in harsh environments, including extended operational temperature range from -40 to +125 degrees C. They are also functional safety ready and designed for use in ISO 26262 applications.
The LAN8650/1 MAC-PHYs are supported with a set of network analysis tools, the LAN8651 SPI evaluation board and MPLAB Harmony 3. The MAC-PHYs are available to purchase now.

STM32H5 discovery kit builds a case for secure, smart, connected devices

Fri, Sep 15, 2023

Support for Secure Manager, a turnkey SoC which integrates core security services certified and maintained by ST is included in the STM32H5 discovery kit by STMicroelectronics.
The development board is for creating diverse applications with the company’s STM32H5 microcontrollers. The STM32H5 devices are intended for high performance processing and advanced security in a wide range of applications, including smart sensors, smart appliances, industrial controllers, networking equipment, personal electronics and medical devices.   The STM32H573I-DK discovery kit enables developers to explore all the integrated features of the STM32H5, such as analogue peripherals, timers, the ST ART (Adaptive Real-Time) accelerator, media interfaces and mathematical accelerators. This makes it easy to evaluate new designs for industrial programmable logic controllers (PLC), motor drives, and smart controllers for appliances, for example, air conditioners, refrigerators and washing machines. Other potential applications include alarm controllers, communication hubs and smart lighting controls.
The STM32H573I-DK Discovery kit is a development board that includes an STM32H5 microcontroller, colour touch display, digital microphone, and interfaces such as USB, Ethernet, and Wi-Fi. The board also features an audio codec, flash memory, and headers for connecting expansion shields and daughterboards.
To simplify the development process, the STM32CubeH5 microcontroller software package consolidates all the necessary components required to develop an application on the STM32H5, including examples and application code. The package is fully integrated into the STM32Cube ecosystem, which contains additional software to assist with application development. ST also offers the STM32CubeMX tool for configuring and initialising the microcontroller.
The STM32H5 microcontroller features the Arm Cortex-M33 embedded microcontroller core running at 250MHz and is the first microcontroller to support ST’s Secure Manager SoC security solutions. The microcontrollers combine Arm TrustZone security with ST’s STM32Trust framework to provide trusted storage, cryptography, attestation and updates. They embed side-channel protected hardware cryptographic accelerators and target recognised security certifications, PSA Certified Level 3 and GlobalPlatform SESIP3.
ST has created the STM32H573I-DK Discovery kit with examples showing how to use the security services and integrated all the necessary software tools and support in the STM32Cube development ecosystem.
The Discovery kit as well as the H5 Nucleo Board Nucleo-H563ZI are available now available from ST’s eStore and authorised distributors.
