NSM201x-P is an integrated current sensor with high precision and 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. NSM201x-P senses the magnetic field generated by the Busbar current flowing under the chip to indirectly detect he current. NSM201x-P 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, NSM201x-P can reach a working voltage for basic isolation of 1618Vpk, and it can withstand 10kV surge voltage and 20kA surge current
without adding any protection devices. NSM201x-P has a pseudo-differential output mode (fixed output), the sensibility will not change within a certain supply voltage, eliminating LDO on the system, making BOM simpler.
Due to NSM201x-P 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. NSM201x-P Provides overcurrent protect function and supports adjusting the overcurrent threshold. Support 3.3V/5V power supply (different version)
