Hi All,

Today's press announcement:

Wide-bandwidth 3-axis vibration sensor saves space, energy, and bill of materials in industrial and automotive applications

Combining sensing for three axes in a single digital device, STMicroelectronics’ IIS3DWBG1 wide-bandwidth vibration sensor simplifies design and cuts bill-of-materials costs in industrial and automotive condition-monitoring applications.

The 3-axis IIS3DWBG1 is suitable for use in industrial condition-monitoring systems, where sensor placement and mounting govern measurement accuracy. Its tiny dimensions and wide operating-temperature range of -40°C to 125°C enhance flexibility to place small, externally attached sensors at optimal diagnostic locations regardless how difficult they are. The compact footprint also facilitates integration inside smart motors and smart gearboxes, while the low power consumption helps designers ensure long-lasting operation in battery-powered applications. The sensor’s wide bandwidth and high resolution, as a 3-axis device, simplify capturing patterns associated with defects or wear, as well as equipment setup issues such as looseness and misalignment, to assist with installation, maintenance, and repairs.


In addition to general monitoring of motors and equipment, the IIS3DWBG1 can detect electromechanical vibrations in coils, transformers, snubber capacitors, busbars, connectors and in general vibrations originating in the power electronics module like traction inverter. Automotive brands can thus extend remote diagnostics to cover power modules, as well as traction inverters of electric vehicles to further enhance customer support through predictive maintenance. With its maximum operating temperature of 125°C, the IIS3DWBG1 is also chosen for monitoring circuits and mechanisms in very harsh environments like in hybrid motors.

Featuring extremely stable sensitivity over the operating-temperature range, the IIS3DWBG1 requires no calibration in the final application. Combining flat frequency response from DC to above 6kHz (-3dB point), and noise density of 75µg/√Hz in 3-axis mode, the sensor detects extremely small vibrations and thus provide enhanced early warning to prevent equipment failures. The sensor is highly resistant to mechanical shocks and integrates digital features including configurable low-pass or high-pass filter with selectable cutoff frequency, an embedded FIFO, interrupts, a temperature sensor, and self-test capability.

Housed in a 2.5mm x 3mm LGA-14L package that saves PCB space and eases circuit layout and final product design, the IIS3DWBG1 is in production now. Pricing starts from $12.00 for orders of 1000 pieces.

Power management optimized ICs for STM32 microprocessors in industrial applications

STPMIC1L and STPMIC2L power-management ICs (PMICs) help designers leverage the embedded-processing muscle of ST’s Arm® Cortex®-A microprocessors (MPUs) in performance-oriented industrial applications.

STEVAL-PMIC1LKV1 STMICROELECTRONICS, Evaluation Board, STPMIC1L, Highly integrated Power Management IC | Farnell® UK

STEVAL-PMIC2LKV1 STMICROELECTRONICS, Evaluation Board, STPMIC2L, Highly integrated Power Management IC | Farnell® UK

Tailored for the 32-bit STM32MP1x and 64-bit STM32MP2x series, the new PMICs deliver cost-effective power and protection while saving board space, simplifying hardware design, and minimizing the bill of materials. With multiple fixed and adjustable LDOs and DC/DC buck converters for all MPU power rails, each PMIC also contains an LDO suited to powering external DDR DRAM.

The PMICs target equipment such as point-of-sale (POS) terminals, network gateways, home-automation systems, edge-processing platforms, printers, barcode scanners, and metering systems. With their extended junction temperature rating from -40°C to 125°C, the devices withstand harsh environments in applications like industrial controls, thermostats, and smart-factory devices.

The STPMIC1L for the STM32MP1 series has two DC/DC buck converters and four LDOs, one LDO for DRAM, and two external pins for power control. The STPMIC2L for the STM32MP2 series has three DC/DC buck converters and seven LDOs for the 64-bit MCUs, one DRAM LDO, and three pins for power control. Each has a large input voltage range, from 2.8V to 5.5V, easing the design of equipment powered from a low-voltage AC/DC wall adaptor, USB outlet, or Li-ion or Li-Po batteries.

The buck converters of these PMICs implement adaptive constant on-time (COT) to ensure fast transient response, as well as supporting dynamic voltage scaling for optimal efficiency. Safety and protection include programmable output discharge modes, selectable overcurrent protection (OCP), and power-rail monitoring. The PMICs also handle power-up/down sequencing and meet the MPUs’ accuracy and settling-time specifications.

Two evaluation boards, STEVAL-PMIC1LKV1 and STEVAL-PMIC2LKV1, are available to help engineers kick-start their projects and accelerate development. Each has a dedicated graphical user interface that eases configuring and monitoring the PMIC on the evaluation board and setting up the NVM parameters.

Both STPMIC1L and STPMIC2L are fully supported by the STM32 MPU ecosystem, in OpenSTLinux.

Hi All,

Developer news:

Accelerating AI‑enhanced motor control with machine-learning software pack

Motor-control software has been released to simplify enhancing drives with AI for optimization and predictive maintenance, ready to load on the EVLSPIN32G4-ACT evaluation board and start exploring.

The FP-IND-MCAI1 function pack helps designers navigate the workflow and tools for implementing smart capabilities in industrial drives and servos, home appliances, robotics, and diverse types of actuators. The software includes a sample application to drive a low-voltage three-phase brushless motor with field-oriented control (FOC), HAL and board-specific drivers, and a machine-learning (ML) solution for motor-behavior classification. The ML model is preconfigured to identify normal, high-vibration, and unstable motor conditions.

 Providing a convenient hardware platform, the EVLSPIN32G4-ACT drives 3-phase brushless DC motors up to 250W and provides connections for a vibration-sensing module such as the STEVAL-C34KAT1 or STWIN.box multi-sensor kit. Users can parameterize and interact with the motor through the STM32 Motor-Control Software Development Kit (MCSDK) and customize the ML model using NanoEdge AI Studio to add their own classes.

As a reference design, the EVLSPIN32G4-ACT features the STSPIN32G4 motor-drive system-in-package, which integrates an Arm^® Cortex^®-M4 microcontroller, half-bridge gate drivers, bootstrap diodes, and protection in a 9mm x 9mm outline. Combining the STSPIN32G4 with a MOSFET power stage, current-sense amplifiers, and a temperature sensor, the EVLSPIN32G4-ACT can handle FOC or 6-step control and three-shunt or single-shunt current sensing. Inputs allow speed and position feedback using digital Hall sensors or incremental quadrature encoders.

The FP-IND-MCAI1 function pack is ready to download free of charge. The EVLSPIN32G4-ACT is available through Farnell.
