BQ3050DBTR Description

Short technical summary and product information.

The Texas Instruments BQ3050DBTR is a Compensated End-of-Discharge Voltage (CEDV) Gas Gauge and Battery Pack Manager designed for 2-series, 3-series, and 4-series Li-Ion or Li-Polymer battery packs. This integrated circuit provides advanced features for protection, authentication, and data gathering.

 

Key electrical specifications include support for 2-4 cells, Lithium Ion/Polymer battery chemistry, and an SMBus communication interface. The device offers comprehensive fault protection, including over current, over temperature, over/under voltage, and short circuit protection. It also supports internal cell balancing and sophisticated charge algorithms like JEITA Enhanced Charging and Adaptive Charging.

 

Packaged in a 38-TSSOP, the BQ3050DBTR is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device also includes low power modes, with consumption less than 180 µA in normal operation and less than 76 µA in sleep mode. SHA-1 authentication is integrated for enhanced security.
