TS1103 A 1A, 200V Bidirectional Precision Current-Sense Amplifier OS FEATURES DESCRIPTION The TS1103 is the latest addition to the TS1101 Ultra-Low Supply Current: 1A Wide Input Common Mode Range: +2V to +27V family of bidirectional current-sense amplifiers. Consuming a very low 1A supply current, the Low Input Offset Voltage: 200V (max) Low Gain Error: 0.6% (max) TS1103 high-side current-sense amplifiers combine a Voltage Output 200-V (max) VOS and a 0.6% (max) gain error for cost-sensitive applications. For all high-side Four Gain Options Available: TS1103-25: Gain = 25V/V bidirectional current-sensing applications, the TS1103s are self-powered and feature a wide input TS1103-50: Gain = 50V/V common-mode voltage range from 2V to 27V. A TS1103-100: Gain = 100V/V TS1103-200: Gain = 200V/V SIGN comparator digital output is also provided that 6-Lead SOT23 Packaging indicates the direction of current flow depending on the external connections to the TS1103s RS+ and RS- input terminals. APPLICATIONS Notebook Computers The SOT23 package makes the TS1103 an ideal Power Management Systems choice for pcb-area-critical, supply-current-conscious, Portable/Battery-Powered Systems high-accuracy current-sense applications in all Smart Chargers battery-powered and portable instruments. Smart Phones All TS1103s are specified for operation over the -40C to +105C extended temperature range.
