Avago Technologies announces the development of a new family of ultra-low-power optocouplers with low-power 10MBd digital optocouplers that combine high-efficiency LEDs with high-gain photodetectors to enable design engineers to directly input optocouplers The 1.6 mA low forward drive current connected to the microcontroller output saves the need to use a buffer to push the LED.
It is understood that Avago's innovative ACPL-M61L/061L/064L/W61L/K64L optocoupler uses a unique integrated circuit design and thick insulation material to save power consumption without affecting isolation and insulation performance (power saving) Up to 90%). These digital optocouplers also provide good high voltage performance over the life of the product and meet the safety requirements for reinforced insulation applications. In addition, the Faraday Shielded Photodetector circuit at the LED input can provide the best level of common-mode noise immunity of 35kV/μs in the same class. This optocoupler series can support 3.3V and 5V power supplies. And it provides reliable system performance over the industrial temperature range of -40 to +105oC. This series incorporates features such as UVLO (UnderVoltageLock-Out) to avoid problems with the output during power failure or system replies. In addition, the output of these optocouplers is controllable with a voltage change rate that controls the rise and fall times of the voltage through a wide range of load capacitor values.
Target markets for Avago's new optocoupler family include RS485, CANBus and I2C communication interfaces, microprocessor system interfaces, and digital isolation for digital-to-analog conversion applications such as A/D and D/A. The single-channel ACPL-M61L optocoupler is available in an SO-5 package and is available now in ACPL-061L/064L in SO-8 package, ACPL-W61L in extended SO-6 package, and extended SO-8. The packaged ACPL-K64L is expected to be available by the end of March 2010.
