Dallas Semiconductor Intros DS2761 Battery Monitor

August 27, 2002 by Jeff Shepard

Dallas Semiconductor Corp. (Dallas, TX) announced its new DS2761 lithium-ion battery monitor, which offers the ability to enable the recovery of a fully depleted discharged battery cell by providing a charge path for trickle charging to the cell until normal charging methods can be used.

The DS2761 integrates current, voltage, temperature measurements, non-volatile data storage and lithium-ion protection circuitry, and is suitable for use in the battery packs of hand-held devices where remaining capacity estimation, safety monitoring and battery-specific data storage are needed. Using an optional internal 25-milliohm sense resistor, the monitoring device can measure continuous currents from 625µA to ±1.9A. External filtering allows peak currents >1.9A to be integrated in the current-accumulation (fuel-gauging) measurement.

The DS2761 is available in a 16-pin TSSOP or die-sized flip-chip package. Prices start at $2.55 in 1,000-unit quantities.
