Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.

The HV7801 high side current monitor IC transfers a highside current measurement voltage to its ground referenced output with an accurate voltage gain of fi ve. The measurement voltage typically originates at a current sense resistor which is located in a "high side" circuit, such as the positive supply line.

This monitor HV7801 features a very wide input voltage range, high accuracy of transfer ratio, small size, low component count,low power consumption, ease of use, and low cost. Offl ine applications, battery, and portable applications can be served well due to the wide input voltage range and the low quiescent current.
