General Description
The HV7800 high side current monitor IC transfers a highside current measurement voltage to its ground referenced output with an accurate voltage gain of one. 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 IC features a very wide input voltage range, high accuracy of transfer ratio, small size, low ponent count, low power consumption, ease of use, and low cost. Offline, battery and portable applications can be served equally...
