Overview: NSM2015 Hall-Effect-Based Current Sensor IC with mon-
Mode Field Rejection and Overcurrent protection
Datasheet (EN) 1.0 Product Overview
NSM2015 is an integrated path current sensor with a very low on-resistance of 0.85mΩ, 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.
NSM2015 senses the magnetic field generated by the Busbar current flowing under the chip to indirectly detect the current. pared with the current sampling method of the Shunt+ isolated op-amp, NSM2015 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, NSM2015 can reach a working voltage of 1550Vpk, and it can withstand 10kV surge voltage and 13kA surge current without adding any protection devices.
NSM2015 has a pseudo-differential output mode (fixed output), the output voltage will not change within a certain supply voltage, eliminating LDO on the system, making BOM simpler.
Due to NSM2015 internal accurate temperature pensation 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.
NSM2015 Provides overcurrent protect function and supports adjusting the overcurrent threshold.
Support 3.
