Magnachip Unveils Its First 8th-Generation MXT LV MOSFET

Wed, Jul 31, 2024

Magnachip has introduced its proprietary Super-Short Channel FET II (SSCFET II) technology for the first time in the Company’s new 12V Dual N-channel MOSFET (MDWC12D024PERH). SSCFET II is Magnachip’s latest design technology that significantly reduces the channel length.

Compared to the previous generation product of the same size, the RSS(on) of this product is reduced by approximately 22%. This reduction decreases power loss, shortens smartphone charging times, and lowers the internal temperature of smartphones by about 12% in fast charging mode.

With global smartphone manufacturers enhancing AI capabilities in smartphones, the importance of MOSFET products is growing. Magnachip’s new 12V MXT LV MOSFET features high power efficiency and is optimised for a wide range of battery protection applications in premium smartphones, particularly on-device AI smartphones.

“Following the development of Super-Short Channel FET I technology and the successful product rollout early last year, Magnachip has now introduced an upgraded Super-Short Channel FET II technology,” said YJ Kim, CEO of Magnachip. “We plan to continue developing innovative high-density cell trench technology and launch advanced power solutions targeting smartphones, smartwatches and earphones throughout the second half of this year.”

Mouser now stocking ST biosensor for smart devices and wearables

Fri, Jul 12, 2024

The ST1VAFE6AX provides design engineers with next generation biopotential signal detection and motion tracking for a variety of applications, including heart rate, pulse monitoring, electrocardiogram (ECG) and activity tracking for wearables and portable medical devices.

The ST1VAFE6AX features a vertical analogue front end (vAFE) channel to detect biopotential signals and includes a 6-axis inertial measurement unit (IMU) for motion tracking. This biosensor embeds advanced dedicated features and data processing for motion processing like the finite state machine (FSM), sensor fusion low power (SFLP), adaptive self-configuration (ASC), and machine learning core (MLC) with exportable artificial intelligence (AI) features and filters. The device fully synchronises biopotential and motion sensing for context-aware analysis. The ST1VAFE6AX biosensor’s compact 2.5 × 3.0 × 0.71 mm footprint makes it ideal for space-constrained applications. Application development with ST1VAFE6AX biosensor is supported by the STEVAL-MKI242A adapter board.

The STEVAL-MKI242A adapter can also be used with the STMicroelectronics STEVAL-MKI109V3 motherboard, the STEVAL-MKBOXPRO programmable wireless box kit, or the X-NUCLEO-IKS4A1 motion MEMS and environmental sensor expansion board.

Omnivision launches newest generation of the World’s smallest shutter image sensor

Wed, Jul 10, 2024

Omnivision has announced the new OG0TC BSI global shutter (GS) image sensor for eye and face tracking in AR/VR/MR consumer headsets and glasses. For the first time ever, Omnivision is bringing its patented DCG high dynamic range (HDR) technology to the AR/VR/MR market in the 2.2-micron (µm) pixel OG0TC GS image sensor.

With a package size of just 1.64mm x 1.64mm, the OG0TC is an ultra-small and low-power image sensor for optimizing primarily inward-facing tracking cameras. This small form factor is key to industrial designs as multiple cameras are required for tracking all aspects of the face (eyes, brows, lips, etc.). The OG0TC is pin-to-pin compatible with Omnivision’s previous-generation BSI GS image sensor for easy upgrades.

“Ultra-low power consumption is critical for AR/VR battery-powered devices, and our OG0TC BSI GS image sensor reduces power by more than 40% over our previous-generation OG0TB sensor, which is already an extremely low-power device,” says Devang Patel, marketing director – IoT/Emerging, Omnivision. “Pin-to-pin compatibility makes the upgrade to the OG0TC easy for our customers, so they do not need to make any change to their design to save power and enjoy new features like DCG™ technology.”

Key features of the OG0TC image sensor include:
● The sensor is built on Omnivision’s PureCel Plus-S stacked-die technology.
● It features Omnivision’s patented DCG HDR technology and offers 400×400 resolution with a 2.2µm pixel in a 1/14.46-inch optical format.
● Nyxel technology enables the best quantum efficiency at the 940nm near-infrared (NIR) wavelength for sharp, accurate images of moving objects.
● It consumes less than 40% of the power at 30 frames per second (fps) compared with the previous-generation sensor.
● The sensor’s high modulation transfer function enables sharper images with greater contrast and more detail.
● It supports a flexible interface, including MIPI with multi-drop, CPHY, etc.

Patel adds, “We are excited to introduce our single-exposure DCG HDR technology for ghost-free image capture to the AR/VR market. It already has proven to be extremely successful in the security, mobile and automotive industries.”
