HV7802

High-Side Current Monitor 8V to 450V Configurable Output

Features

General Description

• 8V to 450V Supply Voltage

The HV7802 high-side current monitor IC contains a

transconductance amplifier which translates

• Configurable as a Current or Voltage Output

Device

high-side current measurement voltage into an output

current with resistor-programmable transconductance

gain. An optional second resistor transforms this output

current into an output voltage with an overall voltage

gain set by the ratio of the two resistors.

• 15 mV Maximum Sense Amplifier Offset

• 500 mV Maximum V_SENSE

• 700 ns to 2 µs Fast Rise and Fall Time

• 50 µA Maximum Quiescent Current

The measurement voltage typically originates at a

current sense resistor, which is located in a “high-side”

circuit. An example is a circuit not directly associated

with ground.

Applications

• Switch Mode Power Supply Current Monitor

• Battery Current Monitor

This monitor IC features a very wide input voltage

range, configurable gain, 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.

• Motor Controls
