Low Power R2Coupler with AEC-Q100 Grade 1 Qualification

The Avago ACPL-M71T and ACPL-M72T are high temperature,
digital CMOS optocouplers in SO-5 packages. Suitable for hybrid and electric vehicle applications, the optocouplers use the latest CMOS IC technology to achieve outstanding performance and very low power consumption. All devices are AEC-Q100 compliant and operate over the –40°C to 125 °C temperature range.

The ACPL-M71T uses a high speed LED, and the ACPL-M72T uses a low current LED for lower power dissipation. The high speed ACPL-M71T featuring a 35 ns maximum propagation delay (IF =10 mA). The ACPL-M72T optocoupler features very low power. With a low 4 mA LED drive current, ACPL-M72L typical propagation delay is 55 ns.

Each digital optocoupler has a CMOS detector IC, an integrated
photodiode, a high speed transimpedance amplifier, and a voltage comparator with an output driver.

All Avago R2Coupler optocouplers feature reinforced insulation
and reliability that delivers safe signal isolation in critical automotive and high temperature industrial applications.
