HV7800

High-Side Current Monitor 8V to 450V Voltage Gain of 1

Features

General Description

• Supply Voltages from 8V to 450V

• Voltage Output Device

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.

• Typical Gain 1 ±1%

• Maximum V_SENSE, 500 mV

• Fast Rise and Fall Time, 700 ns to 2 µs

• Maximum Quiescent Current 50 µA

• Available in 5-Lead SOT-23 Packages

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.

Applications

• Switch Mode Power Supply Current Monitor

• Battery Current Monitor

• Motor Controls

• Telecommunications
