... Referring to the typical application circuit on Page 1, the inputs of the op-amp-based circuit are connected across an external RSENSE resistor that is used to measure load current. At the non-inverting input of the TS1100 (the RS+ terminal), the applied voltage RSENSE. Since the RS- terminal is LOAD the non-inverting input of the internal op amp, op-amp ...

... For optimal circuit performance, the TS1100 should be in very close proximity to the external current- sense resistor and the pcb tracks from RSENSE to Figure 2: Using Two TS1100s for Bidirectional Load Current Detection Page 10 the RS+ and the RS- input terminals of the TS1100 should be short and symmetric. Also recommended are a ground plane and surface mount resistors and capacitors ...
