BQ29330DBTRG4 Description

Short technical summary and product information.

The BQ29330DBTRG4 from Texas Instruments is an analog front-end (AFE) integrated circuit designed for 2, 3, and 4-series cell lithium-ion or lithium-polymer battery pack protection. It offers comprehensive protection features including overcurrent, over/under voltage, and short circuit detection.

 

This device supports cell balancing and includes FET drive capabilities for charge and discharge control. The integrated I2C-compatible interface allows for communication with a host system, providing access to battery information. It also features two low dropout regulators (LDOs): a 2.5-V, 16-mA LDO and a 3.3-V, 25-mA LDO.

 

The BQ29330DBTRG4 is supplied in a 30-TSSOP package and is designed for surface mount applications. It operates within a supply voltage range of 4.5 V to 28 V and has a typical operating current of 100 µA. The operating temperature range is -40°C to 110°C, making it suitable for a variety of demanding applications.

 

Key features include multi-cell support, separate MCU requirement, and host control for sleep and ship power modes. It is capable of operation with a 5-mΩ sense resistor and provides individual cell voltages and battery voltage to the battery management host.
