LG and Infineon to introduce LG G8ThinQ with front-facing Time-of-Flight camera

Posted on by mixos

With Infineon’s REAL3™ Image Sensor Chip, LG Offers Enhanced Security and Depth Measuring Selfie Camera

LG Electronics and Infineon Technologies AG have teamed up to introduce leading edge Time-of-Flight (ToF) technology to smartphone selfie photo lovers world over.

Infineon’s REAL3™ image sensor chip will play a key role in the front-facing camera of the upcoming LG G8 ThinQ, to be unveiled in Barcelona during Mobile World Congress 2019. Building upon the combined expertise of Infineon and pmdtechnologies in algorithms for processed 3D point clouds (a set of data points in space produced by 3D scanning), the innovative sensor will deliver a new level of front camera capability in a smartphone.

While other 3D technologies utilize complex algorithms to calculate an object’s distance from the camera lens, the ToF image sensor chip delivers more accurate measurements by capturing infrared light as it is reflected off the subject. As a result, ToF is faster and more effective in ambient light, reducing the workload on the application processor thereby also reducing power consumption.

And due to its fast response speed, ToF technology is widely used in various biometric authentication methods, such as face-recognition. What’s more, because ToF sees objects in 3D and is not affected by light from external sources, it delivers an excellent recognition rate, both indoors and out, ideal for implementation in augmented reality (AR) and virtual reality (VR) applications.

The world’s leading manufacturer of power semiconductors, Infineon is also recognized for its technological excellence in sensor solutions. The German chip maker enables highly reliable automotive, power management and digital security applications. The company developed the ToF technology featured in the LG G8 ThinQ for use in both premium, high-end smartphones as well as mid-end devices.

Infineon is poised to revolutionize the market, said Andreas Urschitz, division president of Infineon’s Power Management & Multimarket division.

We have demonstrated service beyond the mere product level – specifically catering to phone OEMs, associated reference design houses and camera module manufacturers. Within five years, we expect 3D cameras to be found in most smartphones and Infineon will contribute a significant share.

Keeping in mind LG’s goal to provide real value to its mobile customers, our newest flagship was designed with ToF technology from inception to give users a unique and secure verification system without sacrificing camera capabilities,

said Chang Ma, senior vice president and head of Product Strategy at LG Mobile Communications Company.

The LG G8 ThinQ featuring ToF will be the optimal choice for users in search of a premium smartphone that offers unmatched camera capabilities.

Linear LED controller ICs target dimmable lighting applications

Posted on by mixos

Two linear LED controller ICs have been added to the BCR portfolio, by Infineon Technologies. The BCR601 has voltage feedback to the primary side (also known as active headroom control or AHC), for cost effective and power efficiency LED driver applications.

The BCR602 targets dimmable LED applications such as light engines, modules and strips. It has a wide voltage range of up to 60V makes it suitable for 48V designs and DC/DC grids, confirms Infineon.

The supply voltage of both LED controller ICs ranges from 8.0 to 60V up to the SELV limit. Both the BCR601 and BCR602, operate with an external driver transistor, either an NPN bipolar transistors or an N-channel MOSFET to support a wide LED current and power range.

The ICs allow the LED current to be adjusted by resistors as well as dimmed analogue. The BCR602 also accepts digital PWM up to 3.5 kHz and combined dimming.

Both the BCR601 and BCR602 represent an inherent AC ripple suppression, driving a constantly stable LED current to prevent light flicker.

The AHC of the BCR601 allows controlling the output voltage of the primary side converter such as the XDPL8218 flyback controller from Infineon. This architecture helps a linear LED controller to achieve maximum system efficiency by actively adjusting the AC/DC feedback loop to set minimum voltage headroom.

Adjusting the minimum necessary voltage across the pass transistor optimises system efficiency which can normally only be achieved by secondary switched mode device, points out Infineon, to reduce component temperatures and stress. This construction also reduces EMI compared to switched mode supplies in combination with a low bill of materials, adds Infineon. Additionally, the BCR601 features an adjustable over-voltage protection to prevent any damage to the LEDs.

Both ICs also offer embedded hot-plug protection. This allows connecting or disconnecting the LED load without power down protecting the LEDs from electrical over-stress events. The over-temperature protection reduces the LED current by 30 per cent of the nominal current as soon as the junction temperature exceeds the defined threshold. The LED controller ICs resume regular operation as soon as the temperature drops below the hysteresis.

HS101: A high quality, and Cheap DIY Oscilloscope

Posted on by mixos
HS101 Demo

The Oscilloscope is a test instrument used for the visualization and observation of varying signal voltages, usually as a two-dimensional plot with one or more signals plotted against time. They are used in the design and debugging of electronic devices to view and compare waveforms, determine voltage levels, frequency, noise and other parameters of signals applied at its input as it changes with time. This makes Oscilloscopes a very important tool on the desk of an electronics engineer or maker. However, Oscilloscopes are quite expensive, they cost between $45 – $100 for a small oscilloscope and above $300 for advanced oscilloscopes, which puts them beyond the reach of basic users. But what if we could create something cheaper, compact, and highly functional using the components familiar to makers? That is the question that led to today’s tutorial.

For today’s tutorial, we will build the HS101 Oscilloscope. The HS101 Oscilloscope setup comprises of the HS101 portable and compact DIY oscilloscope, connected to an Android-based mobile phone or tablet running the HScope app.  The oscilloscope is based on the STM32F103 microcontroller which has 2 fast, 12-bits ADC and it samples the signal to be examined (after it has passed  condition elements, like a network of resistors capacitors and diodes) on board.
