Digital Optocouplers suit optical isolation applications.
October 14, 2009 -
ACPL-M61L/061L/064L/W61L/K64L optocouplers operate in -40 to +105°C tempertures from 2.7-5.5 V supply. Combining LED and integrated high gain photo detector, 10 Mbd devices have forward drive current at 1.6 mA, allowing designers to interface optocoupler input directly from microcontroller output - eliminating use of buffers to drive LED. Slew-rate controlled output controls voltage rise and fall times over wide range of load capacitances.
Avago Technologies Announces New Family of Ultra-Low Power Optocouplers for Use in Optical Isolation Applications
Innovative Design Will Enable the Next Generation of Energy Efficient Optical Isolators to Operate on 90 Percent Less Power
SAN JOSE, CA, and SINGAPORE, September 23, 2009 -- Avago Technologies (Nasdaq: AVGO) today announced that it has developed a new family of ultra-low power optocouplers that will pave the way for a new generation of optical isolators that can operate on approximately 90 percent less power than today's standard optocouplers. Utilizing a unique integrated circuit design and thick insulation material, Avago's innovative ACPL-M61L/061L/064L/W61L/K64L optocouplers offer a significant reduction in power requirements without compromising isolation and insulation performance. These digital optocouplers also provide good high voltage performance over the lifetime of the product while meeting the requirements of safe insulation for reinforced applications. This new optocoupler family targets designers of communication interfaces (RS485, CANBus, and I2C), microprocessor system interfaces, and digital isolation for A/D, D/A conversion applications. Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.
Avago's ultra low power 10MBd digital optocouplers combine a high efficiency light emitting diode (LED) and an integrated high gain photo detector which results in low forward drive current (1.6 mA) that will enable designers to interface the optocoupler input directly from the microcontroller output - eliminating the use of buffers to drive the LED. Moreover, the use of the LED input with a faraday shielded photodetector circuit enables 'best in class' application level common mode noise immunity (35kV/µs typical). This optocoupler family supports both 3.3V and 5V supply voltages, and provide reliable system performance in industrial temperatures ranging from -40 to +105 degrees C.
The ACPL-M61L/061L/064L/W61L/K64L family integrates a feature similar to 'under voltage lock-out' that prevents output disruption during a power supply loss or system recovery. Additionally, the output of these optocouplers is designed with a slew-rate controlled feature to allow the voltage rise and fall times to be controlled over a wide range of load capacitances.
Key Features
o Low power consumption: 1.3mA/channel maximum IDD2 current
o Low input drive current capability: 1.6mA
o High dynamic and static CMR performance (35kV/µs typ.)
o Wide supply voltage range: 2.7 - 5.5V
o High speed: 10 Mbd
o Available in a variety of packages including multichannel small outline
o Safety approvals for reinforced insulation pending: IEC/EN/DIN EN 60747/UL 1577/CSA
