bq29330 Datasheet Lithium-ion Or Lithium-polymer Battery Protection

Manufacturer: Texas Instruments

Overview: bq29330 www.ti.com SLUS673E – SEPTEMBER 2005 – REVISED MARCH 2012 2-SERIES, 3-SERIES, AND 4-SERIES CELL LITHIUM-ION OR LITHIUM-POLYMER BATTERY PROTECTION AFE Check for Samples:.

General Description

The bq29330 is a 2-series, 3-series, and 4-series cell lithium-ion battery pack full-protection analog front end (AFE) IC that incorporates a 2.5-V, 16-mA and 3.3-V, 25-mA low dropout regulator (LDO).

The bq29330 also integrates an I2C-compatible interface to extract battery parameters such as battery voltage, individual cell voltages, and control output status.

Other parameters such as current protection thresholds and delays can also be programmed into the bq29330 to increase the flexibility of the battery management system.
