Features

Description

Current sensing is very useful for protecting

applications. The STEVAL-ISQ013V1

demonstration board implements a low-side

current sensing which consists in placing a sense

resistor between the load and the circuit ground

and the resulting voltage drop is amplified using a

TS507 op amp.

The common mode voltage is close to ground,

whatever the voltage of the power source, so the

current sense voltage can be amplified by this low

voltage op amp without any restrictions.

The circuit offers very stable electrical

characteristics over the entire supply voltage

range and is particularly intended for automotive

and industrial applications.
