Infineon CoolSET™ – Embedded Power in Home Applications

MicroCrystal RV-8803 – A Really Accurate RTC June 17, 2019- RTC chips traditionally were the domain of Maxim and NXP. Switzerland-based MicroCrystal recently made quite a buzz with its RV-8803, which offers simple integration, an I2C interface and extreme accuracy. Let us start out by looking at a system overview. Figure one shows how this I2C RTC is made up internally – interested observers note … Continue reading MicroCrystal RV-8803 – A Really Accurate RTC
Analog Devices’ LTM2887 – If a Digital Bus Needs Galvanic Isolation June 15, 2019- In theory, digital buses are intended to connect things to one another. Sadly, one sometimes wants but a logical connection – in many cases, galvanic isolation helps out. Should you ever feel like isolating very fast buses, definitely give the LTM2887 a chance. From a technical point of view, Linear Technologies attempt at entering the … Continue reading Analog Devices’ LTM2887 – If a Digital Bus Needs Galvanic Isolation
AVAGO APDS-9008 or APDS-9005-020 – Keeping an Eye on Ambient Light June 14, 2019- Recent times saw quite a bit of interest for part numbers such as the APDS-9008 or APDS-9005-020 – they are a very interesting type of ambient light sensor. One of the oldest questions in regards to light sensors involves their spectral sensitivity. If a part is to output but one voltage level, the conversion between … Continue reading AVAGO APDS-9008 or APDS-9005-020 – Keeping an Eye on Ambient Light
STMicroelectronics’ LIS2DH12 – Low Power Motion Sensing June 12, 2019- Apple’s iPhone introduced gyroscopic sensors to a wider range – before that, accelerometers were not commonly found in consumer hardware. STM sells excellent parts which, however, get little media attention – time to take a look at the LIS2DH12. Integrating the part into your circuit as an MPU6500 alternative or MPU9500 alternative is not difficult. … Continue reading STMicroelectronics’ LIS2DH12 – Low Power Motion Sensing
Panasonic AMG8833 – FLIR for cheap June 7, 2019- FLIR made infrared thermal sensors cool – sadly, their parts are all but cheap (and suffer from export control problems). Panasonic’s Grid-EYE family is a low-resolution alternative which comes at significantly lower cost. From a technical point of view, Panasonic’s image sensor could not be simpler. We are looking at an 8×8 sensor with an … Continue reading Panasonic AMG8833 – FLIR for cheap
DipTronics DTS-62R-V – Small Switch, Very Big (and Very Cheap) June 5, 2019- When yours truly was but a lowly cadet, various US manufacturers produced (pricey but quite reliable) switches. Chinese vendors recently started to catch up – seeing the DTS-62R-V top our customer interest list shows that the run stage of the crawl-walk-run cycle is reached. DipTronics has been around the Asian switch market for ages, exhibiting … Continue reading DipTronics DTS-62R-V – Small Switch, Very Big (and Very Cheap)

5th Generation CoolSET™ –
high efficiency, integrated power stage IC

Infineon’s CoolSET™ offer high performance with the integration of latest 700/800V CoolMOS™ P7 power MOSFETs and provide the auxiliary SMPS full system solution, ideal for home appliances.

With Infineon and Avnet Silica as your partner, you will be able to focus on the functionality which distinguishes your major home appliance designs without worrying about the need to develop complex power supplies. Read more about Infineon’s integrated solutions for embedded power and lighting in major home applications.

CoolSET™ is available in both through-hole and SMD packages and thereby eliminates the need of heatsink and reduces BOM count with a small footprint. In addition to the typical output protection such as output short, overload and over-voltage protection, the 5th generation controller is incorporating additional protections to detect abnormal line input conditions such as over-voltage and under-voltage protection.

Key Features

• Integrated 700 V and 800 V superjunction MOSFET with avalanche capability
• Comprehensive suite of protection which include input OVP, brown in/out, pin short to GND and OTP with hysteresis
• Innovative quasi-resonant switching scheme to minimize frequency spread under different line input conditions

Key benefits

• High efficiency with latest CoolMOS™ P7 family and quasi-resonant switching scheme
• Auto-restart recovery scheme to minimize interruption to system operation
• Extensive protection coverage to increase system robustness
• Rapid start-up performance with cascode configuration
