2.3 SIGN Comparator Output

As shown in the TS1101/03’s block diagram, the design of the TS1101/03 incorporated one additional feature: an analog comparator

whose inputs monitor the internal amplifier’s differential output voltage. While the voltage at the TS1101/03’s OUT terminal indicates the

magnitude of the load current, the TS1101/03’s SIGN output indicates the load current’s direction. The SIGN output is a logic high when

SIGN comparator’s transfer characteristic is illustrated in the figure below. Unlike other current-sense amplifiers that implement a OUT/
