HV7800数据手册集成电路（IC）的电流调节/管理规格书PDF

描述 Description

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.
