DS2762

High-Precision Li+ Battery Monitor With Alerts

www.maxim-ic.com

GENERAL DESCRIPTION

The DS2762 high-precision Li+ battery monitor is a

data-acquisition, information-storage, and safety-

protection device tailored for cost-sensitive battery

pack applications. This low-power device integrates

precise

temperature,

voltage,

and

current

measurement, nonvolatile (NV) data storage, and Li+

protection into the small footprint of either a TSSOP

package or flip-chip package. The DS2762 is a key

component in applications including remaining

capacity estimation, safety monitoring, and battery-

specific data storage.

FEATURES

Li+ Safety Circuit

Overvoltage Protection

Overcurrent/Short-Circuit Protection

Undervoltage Protection

Host Alerted When Accumulated Current or

Temperature Exceeds User-Selectable Limits

0V Battery Recovery Charge

Available in Two Configurations:

Internal 25mW Sense Resistor

External User-Selectable Sense Resistor
