Avago Technologies Compact Low Power ACPL-M50L Single Channel 1MBd Digital Optocoupler

Avago’s compact low power ACPL-M50L single channel optocoupler, which operates on approximately 80 percent less drive current than today’s standard 1MBd digital optocouplers, targets designers of communication interfaces, microcontroller system interfaces, switching power supplies, and digital isolation for A/D, D/A conversion applications. The ACPL-M50L provides superior high voltage performance over the lifetime of the product while meeting safe insulation requirements for reinforced applications. Available in a small outline-5 (SO-5) package size, Avago’s ACPL-M50L high speed digital optocoupler supports a wide supply voltage range from 2.7 to 24-volts and is driven by low forward drive current (IF > 3mA) with a high current transfer ratio (CTR > 80 percent min.) to allow direct drive from a microcontroller without the need to add a buffer chip…

Avago Technologies Announces Industry’s Most Energy Efficient 1MBd Digital Optocoupler for Signal Isolation Interfaces

Compact Digital Optocoupler Operates on 80 Percent Less Drive Current than Similar 1MBd Optocouplers Offered by Other Suppliers

Avago Technologies (Nasdaq: AVGO) a leading supplier of analog interface components for communications, industrial and consumer applications, announced the industry’s most energy efficient 1MBd digital optocoupler. Avago’s compact low power ACPL-M50L single channel optocoupler, which operates on approximately 80 percent less drive current than today’s standard 1MBd digital optocouplers, targets designers of communication interfaces, microcontroller system interfaces, switching power supplies, and digital isolation for A/D, D/A conversion applications.

The ACPL-M50L provides superior high voltage performance over the lifetime of the product while meeting safe insulation requirements for reinforced applications. Available in a small outline-5 (SO-5) package size, Avago’s ACPL-M50L high speed digital optocoupler supports a wide supply voltage range from 2.7 to 24-volts and is driven by low forward drive current (IF > 3mA) with a high current transfer ratio (CTR > 80 percent min.) to allow direct drive from a microcontroller without the need to add a buffer chip.

Separate connections for the photodiode bias and output transistor collector of the ACPL-M50L increases its speed up to a hundred times over that of a conventional photo-transistor by reducing the base-collector capacitance. Additionally, this optocoupler operates over a wide temperature range from -40 to +105 degrees-C making it ideal for use in harsh industrial environments.
