Hcpl 7840 Hcpl-7840 Isolated Amplifier For Current Sensing portable battery charger with display Super Battery Charger JB-628 AAThe HCPL 7840 isolation amplifier family was designed for current sensing in electronic motor drive applications. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the HCPL 7840. A differential output voltage is created on the other side of the HCPL 7840 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to
