Packing TypeNot Applicable
RoHs compliantEcopack2
GradeIndustrial
Package NameCARD

The STEVAL-ISQ014V1 product evaluation board implements low-side current sensing which consists in placing a sense resistor between the load and the circuit ground. The resulting voltage drop is amplified using a TSZ121 op amp.The common mode voltage is close to ground, whatever the voltage of the...
