General Description
The HV7801 high side current monitor IC transfers a highside
current measurement voltage to its ground referenced
output with a voltage gain of five. 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 component count,
low power consumption, ease of use, and low cost. Offline
applications, battery, and portable applications can be served
equally well due to the wide input voltage range and the low
quiescent current.
