... Smart Phones TYPICAL APPLICATION CIRCUIT The Touchstone Semiconductor logo is a registered trademark of Touchstone Semiconductor, Incorporated. DESCRIPTION The TS1103 is the latest addition to the TS1101 family of bi-directional current-sense amplifiers. Consuming a very low 1μA supply current, the TS1103 high-side current-sense amplifiers combine a 200-µV (max) V and a 0 ...

... RS+ is proportional OUT SENSE RS+ inverting input of the TS1103 (the RS- terminal), the applied voltage is I terminal is the non-inverting input of the internal op amp, op amp feedback action forces the inverting input of the internal op amp to the same potential (I x RSENSE). Therefore, the voltage drop ...

... Since M1’s drain terminal is connected to ROUT, the output voltage of the TS1103 at the OUT terminal is, therefore When the voltage at the RS- terminal is greater than the voltage at the RS+ terminal, the external VSENSE voltage drop is impressed upon RGAINB. ...

... Swing vs. Applied Input Voltage at V OUT and Desired V SENSE As there is no separate power supply pin for the TS1103, the circuit draws its power from the voltage at its RS+ and RS- terminals. Therefore, the signal voltage at the OUT terminal is bounded by the minimum voltage applied at the RS+ terminal. Therefore, ...

... For optimal circuit performance, the TS1103 should be in very close proximity to the external current- sense resistor and the pcb tracks from RSENSE to the RS+ and the RS- input terminals of the TS1103 should be short and symmetric. Also recommended are a ground plane and surface mount resistors and capacitors ...
