New from Avago Technologies is the ACPL-M21L/021L/024L/W21L/K24L family of low-power 5 MBd optocouplers. They are designed to meet customer needs for high isolation voltage and common-mode rejection (CMR) performance, thanks to the performance of the new LED and detector IC design.
The devices 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 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 wave-shaping.
An internal shield also guarantees high common-mode rejection (CMR) of minimum 25 kV/µs at 1000 V common-mode voltage. ACPL-x2xL optocouplers operate at 3,3 V/5 V 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. The ACPL-024L and ACPL-K24L are dual-channel devices 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 for reinforced insulation, UL 1577 and CSA.
