NOVOSENSE NSM2311 integrated current sensor with a low impedance and a high current capacity and an isolated analog output, for motor and power current.

The NSM2311 is a NOVOSENSE integrated current sensor that measures the current with a low impedance and a high current capacity in a single module. Instead of a discrete shunt and an amplifier, the device places the conductor and the sensing together, so the measurement is compact, the insertion loss is low and the isolation between the high-current path and the output is built in, which suits a high-side or a high-voltage measurement where a direct shunt would be difficult. The output is an analog signal that the controller reads directly, and the design targets the current measurement in a motor drive, a power converter and a battery system, with the accuracy and the thermal behavior that a power application needs. Because the current path and the sensing are integrated, the layout is simple and the parasitic inductance is low, which helps in a fast-switching stage. The device is designed for an automotive and an industrial environment. Typical applications include the phase current of a motor drive, the output current of a power converter and the current of a battery and a charging system. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the device, plan the isolation and the layout and confirm the accuracy over temperature.

FAE Professional Review

The NSM2311 is the integrated current sensor to choose where the current is high and a low impedance and a high capacity matter, because the conductor and the sensing are in one module, so the insertion loss and the layout are both simple. The isolated output suits a high-side measurement. Keep the high-current path wide and the signal path separated and confirm the accuracy at the temperature extremes.

Frequently Asked Questions

What projects suit the NSM2311?

It suits a high-current measurement where a low impedance and a high current capacity are needed, such as a motor phase, a power converter output or a battery, because the conductor and the sensing are integrated in one module with an isolated output.

Confirm the current range and the layout.

Integrated sensor or a shunt and amplifier?

Choose the integrated sensor where the current is high, the insertion loss and the layout matter and the isolation must be built in. Choose a shunt and a current sense amplifier such as the NSCSA240-Q where a shunt is already in the design and a high accuracy with a good PWM transient rejection is needed.

Our FAE team can help choose.
