“These latest solutions are pin-to-pin compatible with some of our previous-generation sensors so customers can seamlessly upgrade to higher resolution devices. OS04J10 features Omnivision’s unique DCG Technology that extends HDR by sampling conversion gains twice and adding exposures for accurate scene reproduction, delivering the most accurate, low-noise and motion artifact-free captures both indoors and outdoors” said Cheney Zhang, senior marketing manager at Omnivision.

Key features of the OS04J10 image sensor:
● 2560 x 1440 resolution (4MP)
● Frame rate of 60fps
● 2-exposure staggered HDR and DCG HDR technology
● NIR quantum efficiency: 850nm and 940nm
● Ultra-low power (<200mW) and noise, long battery life
● High performance 2.9 µm PureCel Plus BSI Pixel
● 1/1.88-inch optical format
● Interface: MIPI/LVDS: 2/4-lane
● CSP package
Key features of the OS05L10 image sensor:
● 2880 x 1620 3K resolution (5MP) to capture real-time fast moving objects
● Frame rate of 30fps
● 2-exposure staggered HDR
● High sensitivity 2.0 µm OmniPixel®3-HS FSI Pixel
● 1/2.7-inch optical format (common size for cost-effective upgrades)
● Interface: MIPI: 1/2-lane
● CSP package

The OS04J10 also features a spread spectrum clocking (SSC) mode that reduces electromagnetic interference (EMI) and radiation. Both sensors are available for sampling now and will be in mass production in Q3 2024.

ST releases energy-efficient autonomous inertial measurement unit

Thu, Jun 06, 2024

The STMicroelectronics ISM330BX 6-axis inertial measurement unit (IMU) combines edge-AI processing, an analog hub for sensor expansion, and ST’s Qvar electric charge variations sensing with product-longevity assurance for energy-efficient industrial sensing and motion tracking applications.

The IMU contains a 3-axis gyroscope and a 3-axis accelerometer with a low-noise architecture and bandwidth up to 2kHz, suitable for vibration sensing in machine-tool condition-monitoring applications. Additional use cases include industrial and domestic robots and automated guided vehicles (AGV), intelligent appliances, and motion trackers.

Also integrating ST’s edge-processing engine that teams a machine-learning core (MLC) with AI algorithms and a finite state machine (FSM), the ISM330BX offloads the host processor and saves system power. The IMU also embeds ST’s Sensor Fusion Low-Power (SFLP) algorithm for 3D orientation tracking, which can enhance energy efficiency in applications like robotics and smart safety helmets. Leveraging adaptive self-configuration (ASC), the sensor can also automatically optimise its settings in real-time for best performance and power.

With its autonomous capabilities, the ISM330BX alleviates data transmission between the IMU and host system, as well as offloads the main processor, ensuring low latency and low power consumption. The integrated analog hub provides more opportunities for energy-efficient system integration by directly connecting external analog sensors to the edge-processing engine for data filtering and AI inference. The many power-saving aspects of the ISM330BX help engineers realize innovative industrial sensors and other battery powered smart devices that can be used also to upgrade existing industrial assets making them smarter and ready for industry 5.0

With ST’s Qvar electric charge variation detector also built-in, the IMU can integrate touch and close-proximity detection, or value-added functionality such as water leak sensing, to boost system integration and energy efficiency.

DC-DC converter series from TDK is enhanced with adjustable current limit option

Thu, Jun 06, 2024

TDK has announced the addition of adjustable current limit models to the TDK-Lambda brand 300W rated i7C non-isolated DC-DC converter series. These buck-boost board mount power modules have input ranges of 9 up to 53Vdc with output voltage adjustment from 5 to 28V, 8 to 24V or 9.6 to 48V depending upon the output current rating. The i7C topology enables a seamless transition from buck (voltage reduction) to boost (voltage increase) operation. The “Itrim” output current limit function enables parallel operation of modules for higher power requirements, operation in constant current, or reducing device stress where overloading may occur due to charging large capacitive loads.

The new models are ideal for generating additional high-power DC outputs from 12, 24, and 48V system voltages in medical, automated guided vehicles (AGV), Industrial Mobile Robots (IMR), drones, industrial, test, measurement, and battery-powered equipment.

Having high efficiencies of up to 97% reduces waste heat, allowing the product to operate and deliver high useable power in demanding thermal environments. Under light load conditions, the i7C’s control techniques significantly reduce power consumption. Under zero load conditions, the typical input current for these modules is 5mA. When the module is inhibited, this current can be further reduced to approximately 0.25mA. The low quiescent current allows battery-powered equipment to remain functional longer during periods of non-operation.

These additional models include output voltage adjustment, negative logic remote on-off, output current monitoring, positive remote sense, plus input under-voltage, over-current and thermal protection. A sync function enabling a common operating switching frequency between multiple converters to reduce system noise is also included.

Three mechanical configurations are available; low profile open frame measuring 34 x 36.8 x 14.7mm (LxWxH), baseplate construction for conduction cooling (15.5mm in height), or integral heat sink for convection or forced air cooling (24.9mm in height). The i7C converters have the industry standard 1/16th brick pin-out.

All models are certified to IEC/UL/CSA/EN 62368-1 and carry the CE and UKCA marks for the Low Voltage and RoHS Directives.
