Isolation Amplifiers Integrate Short-Circuit/Overload Detection

Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power inverters. Typical applications include inverter current sensing, motor phase and rail current sensing, switching power supply signal isolation, industrial a/d converters, and general-purpose current sensing and monitoring. The amplifiers come in SO-16 packages measuring 10.3 mm x 10.2 mm x 3.5 mm that comply with most industrial safety standards such as IEC/EN/DIN EN 60747-5-5, UL 1577, and CSA. Other features include a 1 µV/?C offset change versus temperature, CMR of 25 kV/µs at a VCM of 1 kV, and a 20-kHz minimum bandwidth. Price is $3.25 each/10,000. AVAGO TECHNOLOGIES, San Jose, CA.
