Avago Technologies' automotive-grade optocoupler with extended temperature operation is suitable for use in hybrid and electric vehicles. The ACPL-38JT 2.5A optocoupler is qualified to AEC-Q100 Grade 1 stress test requirements, delivering safe electrical signal isolation from -40 to +125°C. The device incorporates an IGBT driver for signal switching, with desaturation detection and fault status feedback systems for constant signal protection. It has reinforced insulation for reliable signal isolation, critical in automotive and high-temperature industrial applications such as isolated IGBT/power MOSFET gate drives, industrial inverters, AC and brushless DC motor drives, and uninterruptable power supplies. During power-up, its under voltage lock-out feature protects the IGBT from receiving insufficient gate voltage by forcing lower output. The integrated driver increases the reliability of a motor drive without the cost, size and complexity of a discrete design.
