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) VOS and a 0.6% (max) gain error for cost-sensitive applications. For all high-side bidirectional current-sensing applications, the TS1103s are self-powered and feature a wide input common-mode voltage range from 2V to 25V. A SIGN comparator digital output is also provided that indicates the direction of current flow depending on the external connections to the TS1103’s RS+ and RS- input terminals.
