Description
The HCPL-7850, HCPL-7851 and ACPL-785E are isolation amplifiers that provide accurate, electrically isolated and amplified representations of voltage and current. When used with a shunt resistor to monitor the motor phase current in a high speed motor drive, the device will offer superior reliability compared with the traditional solutions such as current transformers and Hall-effect sensors.
