Set net news, China, Beijing, China - on September 22, 2016 - Silicon Labs (also name "core technology", NASDAQ: SLAB) has been introduced based on CMOS technology breakthrough isolation type field effect transistor (FET) family products, this enables developers to use your choice of specific applications and high capacity of FET to replace outdated electromechanical relay (EMR) and solid state relay (SSR) based on optical coupler. New Si875x series products are the industry's first isolation FET drive, is designed to use integrated CMOS gelizha transmission power, this eliminates the normally required for isolating the secondary side of the switch power supply, reduce the system cost and complexity. When match with divided FET, Si875x drives provide the first-class EMR/SSR alternative solutions, suitable for motor and valve controller, HVAC relay, battery monitoring, communication lines and communications switch, EV/HEV vehicle charging system and other industrial and automotive applications.
Developers traditionally used in switching applications EMR and SSR based on optical coupler, and both techniques have limitations. EMR is expensive, slow, cumbersome and noise, the use of the disadvantage of EMR cause SSR have double-digit growth rates, but even if it also faces many challenges. Based on optical coupler SSR's inherent limitations, for example due to aging LED a shorter service life, higher temperature reducing the noise of the poor performance and reliability, anti-jamming. In addition, they also can choose only limited integrated FET, further damage to the performance, cost and power consumption.
Silicon Labs based on CMOS Si875x isolation type FET drive provides a better choice, can be used for SSR or EMR application reduce the system cost and power consumption, enhance the system performance. Because Si875x drive do not use LED or optical components, which provide the whole service life of the excellent stability and temperature range. Minimal encapsulation Si875x devices provide completely silent switch characteristics, which makes them become an ideal replacement of bulky EMR solution, the EMR is usually restricted to electronic switching noise, aging, as well as the challenges of mass production.
Si875x device by using the nominal 10.3 V, 1 ma, extremely low input current and a 1.1 ms response time to drive the FET gate. Increase the input current to 10 ma, can realize fast 94 mu s turn on time. Unique power optimizations can quickly gain maximum current flow, and then once the optional external capacitance discharge, static to keep current most can reduce to 90% of maximum current flow. Flexible between 2.25 to 5.5 V input voltage to support smooth connection to the low power controller. Si875x drive also have optional miller clamp ability, prevent accidental open external FET.
Si875x device has 2.5 kVrms isolation level, in the industry and auto level temperature range (up to + 125 ¡æ), design conforms to the strict UL, CSA, VDE, CQC standard. Multi-function control provide digital CMOS input pin (Si8751 devices) or diode simulation (Si8752 devices), can be very good to adapt to the target application, and the output of the flexible support AC and DC load configuration.
Silicon Labs power supply products, vice President of Ross Sabolcik said: "with unique will be powerful and reliable isolation technique and through the isolation gate based on CMOS transmission power integrated innovation capability, Silicon Labs Si875x drive for old EMR and SSR based on light coupling provided indispensable alternative solution. New products for application developers choose required Si875x family of cost-effective FET provides maximum flexibility, also bring the most advanced solid state switch the simplest migration scheme."
Si875x isolation FET drive series products, the industry advantage in the first isolation SSR solution based on CMOS, support a specific application of FET. First-class noise suppression capability, high reliability and 2.5 kVrms isolation level. , high pressure under the condition of long service life (up to 100) under the condition of 1000 v. • efficient switch: 10.3 V gate voltage and input current in only 1 ma. Wide, 2.25 to 5.5 V input voltage energy-saving can be realized. Features, a unique pin can optimize trade-offs between power/switch time. Miller clamp prevent accidental open external FET. • small SOIC - 8 encapsulation, integrates the isolation and the power capacitor used for low power applications. • AEC - Q100 certification auto device options.
Price and supply Si875x isolation FET drive plate are supply, production quantities and plan in November 2016. Si875x devices support small SOIC - 8 encapsulation, industrial-grade (to 40 ¡ã C to + 105 ¡æ) or car level (to 40 ¡ã C to + 125 ¡æ) environmental temperature range of options. In ten thousand when the purchase quantity, industrial-grade devices unit price is $0.96, the unit price of $1.20 on auto level device. Si8751 - KIT (digital input) and Si8752 - KIT (LED simulation input) assessment suite is now supply, retails for $39.99.
