Supertex inc. HV7800 High Side Current Monitor
8.0 to 450V
Voltage Gain of 1
Features General Description Applications 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,
battery and portable applications can be served equally well
due to the wide input voltage range and the low quiescent
current of the HV7800. в–єв–є Supply voltages from 8V to 450V

в–єв–є 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. SMPS current monitor
