Microchip HV7801K1-G, Current Monitor 5-Pin, SOT-23

The Microchip HV7801K1-G high side current monitor IC transfers a high-side 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, battery, and portable applications can be served equally well due to the wide input voltage range and the low quiescent current.
