ADI LTC2942IDCB#TRMPBF

电池监控器锂离子-40°C ~ 85°C（TA）

Overview

The LTC2942IDCB measures battery charge state, battery voltage and chip temperature in handheld PC and portable product applications. Its operating range is perfectly suited for single-cell Li-Ion batteries. A precision coulomb counter integrates current through a sense resistor between the battery’s positive terminal and the load or charger. Battery voltage and on-chip temperature are measured with an internal 14-bit No Latency ΔΣ™ ADC. The three measured quantities (charge, voltage and temperature) are stored in internal registers accessible via the on-board SMBus/I2C interface.

The LTC2942IDCB requires only a single low value sense resistor to set the measured current range.
