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 […] 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 […] 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 […] 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. […] 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 […] 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 […]
While MOSFETs show up often in OEMsecrets search trends due to various constraints when designing switching regulators, Infineon’s IPP60R060P7XKSA1 gave us a start – Mouser still lists the part is brand-new, the CoolMOS 7 technology was introduced but a few months ago.
The C7 family differs from its predecessor in a variety of factors. Infineon – old hands might know the company is the semiconductor division of Siemens – promise that the part combines the benefits of fast junction MOSFETs with properties usually found in slower MOSFET transistor types.
As usual, the basic specs of the transistor don’t tell us particularly much – the maximum drain source voltage, commonly called Vdc, lays in the range of 600 V. The transistor can handle a drain current of up to 48 amperes of direct current. In this mode, the drain resistance lays in the range of 49 mOhms – a very small value, which lets the part handle this large amount of current.
This being OEMsecrets, we, do not end our trip through the world of transistors here. Instead, let us herd you to a somewhat hidden application note found by Clicking Here. In principle, the most significant benefit of the latest version is smaller structure size – our figure compares the P7 to its predecessor architecture.
Smaller structures improve transistor performance…
In addition to lowering the drain resistance, the newly devised topology also has the benefit of decreasing gate capacitance. This allows switching processes to take place faster, reducing the amount of power dissipated during the transitional process. Yours truly is aware of more than one case where gate capacitances caused problems – most of the heat burned in the transistors is lost during the transition.
The Infineon application note furthermore provides insight into how the IPP60R060P7XKSA1 can benefit you – if your question is related to FET transistors, simply click the link above and have an electrical engineering book in hand.
Furthermore, keep in mind that Siemens also offers additional documentation which, sadly, is a bit hard to find. Visit Here and click on the four small squares at the bottom – the four additional whitepapers provide further insight.
