The TS1101-200EG6T is a bidirectional precision Current Sense Amplifier for use with smart chargers and smart phones. Consuming a very low 1μA supply current, the TS1101 high-side current sense amplifier exhibits a 100μV (maximum) VOS and a 0.6% (maximum) gain error, both specifications optimized for any precision current measurement. For all high-side bidirectional current-sensing applications, the TS1101 is self-powered and feature a wide input common-mode voltage range from 2 to 25V. A sign comparator digital output is also provided that indicates the direction of current flow depending on the external connections to the TS1101's RS+ and RS- input terminals.
