Fully Integrated Current Detection IC Brief Introduction

Product details

Because of the integrated magnetic circuit in the chip, the user can connect the chip directly in series with the measured current loop. Can realize an AC/DC current (0~±50a) isolation detection scheme with 2400vrms dielectric strength without complicated peripheral circuit. The chip is factory calibrated for sensitivity and static (zero current) output voltage, providing a typical accuracy of less than ±1.5% over the full temperature range.
