Chip Measures Current Using Shunt of Any Resistance Made of Any Material
Sendyne Corp.

The SFP101 current, voltage, and temperature measurement IC can work with a shunt of essentially any resistance made from any material. The chip achieves a maximum voltage offset error of less than ±0.15 μV for the measurements of the voltage drop across a shunt and provides user-definable automatic compensation for resistance dependence of the shunt on temperatures from -40°C to +125°C. It is programmable to accommodate shunts with an output voltage from ±10mV to ±300mV. Other features include an accuracy of ±0.05% from -40°C to +125°C when coupled to a 25-µΩ shunt, a continuous current rating of 300A, and a peak current of 2 kA. Additionally, the SFP101 provides on-board calibration for both current and voltage. It stores calibration values and applies them internally, offers separate charge, discharge, and total Coulomb counters, and measures multiple temperature points to ±1°C.
