The TMCS2100-Q1 is a precision multi-sensor coreless current sensing device, designed specifically for the demanding requirements of high voltage, high-current multi-phase systems. This measurement design meets the performance requirements of significantly larger, heavier and more expensive magnetic core-based products while achieving a space-saving footprint, without the requirement to modify or notch the high current carrying bus bars.
AC or DC current flows through a busbar generating a magnetic field. The integrated on-chip Hall-effect sensors measure the magnetic field. Typically, differential coreless current sensing devices are highly susceptible to changes in magnetic field strength due to system manufacturing tolerances, displacement and vibration. The TMCS2100-Q1 utilizes a TI proprietary algorithm to significantly reduce the effect of displacement. Additionally, active frequency compensation is available for eddy current-induced amplitude errors.
The TMCS2100-Q1 characterization process minimizes phase-to-phase magnetic crosstalk error and enables measurement errors below 0.5% at full-scale current levels that can exceed 1000A.
