Product Overview

NSM2016 isanintegrated path current sensorwith a very

low on-resistance of 1.2mΩ, reducing heat loss on thechip.

NOVOSENSEinnovativeisolation technologyandsignal

conditioning design can meet high isolationlevels while

sensing thecurrent flowing through theinternal Busbar. A

differentialHall pair is used internally,so ithas a strong

immunityto external stray magnetic fields.

NSM2016 has a fixed outputmode. Comparedwith the

current samplingmethodof the Shunt+ isolated op amp,

NSM2016 eliminates the need fortheprimary side power

supply andhas a simple and convenient layout.At the

sametime, it hasextremely high isolation withstand

voltageandlifetimestability.

In high-side currentmonitoring applications,NSM2016 can

reach a working voltageof 600Vpk, and it can withstand

6kV surgevoltage without addinganyprotectiondevices.

Dueto NSM2016internalaccuratetemperature

compensationalgorithmandfactoryaccuracy calibration,

this current sensorcan maintain good accuracyin the full

temperature working range,andthecustomer does not

need to do secondary programmingor calibration.

NSM2016 provides overcurrent protect function.

Support 3.3V/5Vpower supply(different version)
