BQ29330DBTR Description

Short technical summary and product information.

The Texas Instruments BQ29330DBTR is a versatile Analog Front End (AFE) integrated circuit designed for robust protection of 2-series, 3-series, and 4-series cell lithium-ion or lithium-polymer battery packs. This device operates within a supply voltage range of 4.5 V to 28 V and features an I2C-compatible interface for communication with a host system.

 

Key electrical specifications include a typical operating current of 100 µA and an operating temperature range of -40°C to 110°C. The BQ29330DBTR integrates essential protection features such as overcurrent, over/under voltage, and short circuit detection. It also includes two low dropout regulators (LDOs): a 2.5-V, 16-mA LDO and a 3.3-V, 25-mA LDO.

 

Packaged in a 30-TSSOP, this surface-mount device is suitable for various battery management applications requiring reliable cell protection. Its design allows direct interface with bq803x-based gas gauge families and supports features like cell balancing drive and NMOS FET drive for charge and discharge control.
