SFP100EVB Current, Voltage and Temperature Measurement Module

This is a LEGACY part, please go to Sensing Family Selection Guide

The Sendyne SFP100EVB is a module that simultaneously measures
bi-directional DC current through a 100-µΩ resistive shunt, voltage, as well as temperature at four points. Rated for the automotive temperature range of –40 °C to +125 °C, the module is capable of resolving currents from 3 mA to 513 A within a single continuous measurement range (without sub-ranging or gain switching), with uniform resolution of 61 µA, and performs automatic charge accumulation for built-in precision Coulomb counting.
The module communicates internally digitized values to a host via a simple LIN-like serial interface.

The SFP100EVB implements several of Sendyne’s patented and patent pending technologies in order to achieve precision current measurements for field use comparable to the precision of metrology grade lab instruments. From +10 °C to +50 °C, the module typically achieves an accuracy of ±0.05 % for both current and voltage measurements; at the extremes of the full operating temperature range, the module achieves an accuracy of ± 0.4 % for current measurement and ± 0.6 % for voltage measurement. Accuracy is defined as the cumulative effect of all possible sources of error, including offset, gain and stability of the built-in precision voltage reference.

A complete evaluation kit for SFP100EVB is available that includes the module, a Serial-to-USB cable, as well as Windows’-based control software. The software provides visual indication of all measured values, both in digital-meter and real time chart formats, as well as automatic saving of all data in files (data logging), with unlimited duration, for off-line review and export in an ASCII format. Furthermore, it allows assessment and control of all internal registers and settings for the SFP100 IC utilized by the module.
