NSI1311-Q1SWVR

The NSI1311-Q1SWVR is a NOVOSENSE automotive-grade isolated amplifier qualified to AEC-Q100 Grade 1, that measures a small differential voltage on the high-voltage side and reproduces it on the low-voltage side with the NOVOSENSE capacitive isolation barrier in between. It shares the approach and the isolation technology of the NSI1300 family, with a linear differential input and a differential output for a good rejection of the common-mode noise, and the automotive qualification and the wide temperature range suit an under-hood design such as a traction inverter or a battery-management system. The capacitive barrier gives a high common-mode transient immunity, so the measurement survives the fast switching of a power stage, and the device operates from about 3 V to 5.5 V. Where the design must meet an automotive requirement and measure a high-side current accurately, the NSI1311-Q1 is the qualified part to use, and it pairs naturally with a NOVOSENSE isolated gate driver and a digital isolator on the same board. Typical applications include the motor and battery current in an electric vehicle, an inverter and a power converter and any automotive high-side current sense. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file.
