NSM2019 Hall-Effect-Based Current Sensor IC with Common-Mode Field Rejection and Overcurrent protection Datasheet
■NSM2019 is an integrated path current sensor with a very low on-resistance of 0.27mΩ, reducing heat loss on the chip.
■NOVOSENSE innovative isolation technology and signal conditioning design can meet high isolation levels while sensing the current flowing through the internal Busbar. A differential Hall pair is used internally, so it has a strong immunity to external stray magnetic fields.
■NSM2019 senses the magnetic field generated by the Busbar current flowing under the chip to indirectly detect the current. Compared with the current sampling method of the Shunt+ isolated op-amp, NSM2019 eliminates the need for the primary side power supply and has a simple and convenient layout. At the same time, it has extremely high isolation withstand voltage and Lifetime stability.
■In high-side current monitoring applications, NSM2019 can reach a working voltage of 1618Vpk, and it can withstand 10kV surge voltage and 20kA surge current without adding any protection devices.
■Due to NSM2019 internal accurate temperature compensation algorithm and factory accuracy calibration, this current sensor can maintain good accuracy in the full temperature working range, and the customer does not need to do secondary programming or calibration.
■NSM2019 Provides overcurrent protect function. Support 5V /3.3V power supply (different version)
