Smart Battery Packs/Chargers
DESCRIPTION
The voltage-output TS1100 current-sense amplifiers
are form-factor identical and electrical improvements
to the MAX9938 and the MAX9634 current-sense
amplifiers. Consuming a very low 1μA supply current,
the TS1100 high-side current-sense amplifiers exhibit
a 100-µV (max) VOS and a 0.5% (max) gain error,
both specifications optimized for any precision current
measurement. For all high-side current-sensing
applications, the TS1100 features a wide input
common-mode voltage range from 2V to 25V.
The SOT23 package makes the TS1100 an ideal
choice for pcb-area-critical, low-current, high-
accuracy current-sense applications in all battery-
powered, remote or hand-held portable instruments.
All TS1100s are specified for operation over the
-40°C to +105°C extended temperature range.

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by product
characterization.
Note 2: Extrapolated to VOUT = 0. ICC is the total current into the RS+ and the RS- pins.
Note 3: Input offset voltage VOS is extrapolated from VOUT with VSENSE set to 1mV.
Note 4: Gain error is calculated by applying two values for VSENSE and then calculating the error of the actual slope vs. the
ideal transfer characteristic:
For GAIN = 25, the applied VSENSE is 20mV and 120mV.
For GAIN = 50, the applied VSENSE is 10mV and 60mV.
For GAIN = 100, the applied VSENSE is 5mV and 30mV.
For GAIN = 200, the applied VSENSE is 2.5mV and 15mV.
Note 5: The device is stable for any capacitive load at VOUT.
Note 6: VOH is the voltage from VRS- to VOUT with VSENSE = 3.6V/GAIN.
