Figure 1 – LMP8646EB
The LMP8646 Evaluation Board (LMP8646EB) is designed to ease evaluation and design-in of Texas
Instruments’ LMP8646, a Precision Current Limiter. The LMP8646 is used to detect small differential
voltages across a sense resistor in the presence of high input common mode voltages. On board with the
current limiter is the LM3102, a Step Down Switching Regulator that is capable of supplying 2.5A to
loads. This document describes super cap and resistive load applications utilizing the LM3102 voltage
regulator and the LMP8646 precision current limiter. The document also provides the schematic, layout,
and BOM for the LMP8646 evaluation board.
