Product Overview

The HCPL-788J-000E is an Isolation Amplifier with short-circuit and overload detection makes motor phase current sensing compact, affordable and easy-to-implement while satisfying worldwide safety and regulatory requirements. A larger analogue output voltage is created on the other side of this optical isolation barrier. The output voltage is proportional to the motor current and can be connected directly to a single-supply A/D converter. A digital over-range output (FAULT) and an analogue rectified output (ABSVAL) are also provided. The wire OR-able over-range output (FAULT) is useful for quick detection of short circuit conditions on any of the motor phases. The wire-OR-able rectified output, simplifies measurement of motor load since it performs poly-phase rectification. Since the common-mode voltage swings several hundred volts in tens of nanoseconds in modern electronic motor drives, this was designed to ignore very high common-mode transient slew rates (10kV/µs).
  • Output voltage directly compatible with A/D converters (0V to VREF)
  • Fast (3µs) short circuit detection with transient fault rejection
  • Absolute value signal output for overload detection
  • 1µV/°C Offset change vs. temperature
  • 25kV/µs Isolation transient immunity

Applications

Motor Drive & Control, Power Management, Sensing & Instrumentation, Test & Measurement, Industrial
