The HV7800 high side current monitor IC transfers a high-side 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 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.
Additional Features
Supply voltages from 8V to 450V
Voltage output device
Typical gain 1±1%
Max VSENSE 500mV
Fast rise and fall time, 700ns to 2.0µs
Maximum quiescent current 50µA
5-Lead SOT-23 Package
