Opkoblere med lavt effektforbrug
Avago Technologies lancerer digitale optokoblere, der forbruger mindre end 10 mW per kanal og understøtter isoleringsspændinger på op til 5kV (in english).
Avago Technologies has announced the ACPL-M21L/021L/024L/W21L/K24L optocoupler family . These optocouplers consume less power as compared to other similar 5MBd optocouplers in the market. The ACPL-x2xL optocouplers are designed to meet customer needs for lower power,higher isolation voltage, and better common-mode rejection (CMR) performance, thanks to the excellent performance of the new LED and detector IC design.Avago Technologies’ digital optocouplers are used in a wide variety of isolation applications ranging from power supply and motor control circuits to data communications and digital logic interface circuits.
The new ACPL-x2xL 5MBd digital optocouplers require minimum LED drive current of 1.6 mA, and detector IC power consumption of less than 1.1 mA. The detector IC contains a CMOS output stage with glitch-free output during power-up and power-down, and optical receiver input stage with built-in Schmitt trigger that provides logic-compatible waveforms, eliminating the need for additional waveshaping.
An internal shield also guarantees high common-mode rejection (CMR) of minimum 25 kV/µs at 1000V common-mode voltage. ACPL-x2xL optocouplers operate at 3.3V/5V power supply with guaranteed AC and DC performance from an extended temperature range of –40°C to +105°C.
The ACPL-M21L, ACPL-021L and ACPL-W21L are single-channel optocouplers in 5-lead small-outline (SO5), 8-lead small-outline (SO8) and stretched 6-lead small-outline (SO6) packages, respectively. Whereas, the ACPL-024L and ACPL-K24L are dual-channels optocouplers in 8-lead small-outline (SO8) and stretched 8-lead small-outline (SO8) packages, respectively.
All new optocouplers are compliant to industrial safety standards such as IEC/EN/DIN EN 60747-5-5 approval forreinforced insulation, UL 1577 and CSA.
