BQ78350DBTR-R1 Description

Short technical summary and product information.

The Texas Instruments BQ78350DBTR-R1 is a battery management controller featuring the Compensated End-of-Discharge Voltage (CEDV) gauging algorithm. It is designed for Li-Ion/Li-Polymer and LiFePO4 battery chemistries, supporting configurations from 3 to 15 series cells.

 

This IC offers flexible communication via I2C and SMBus interfaces and supports battery capacities up to 320 Ahr. It provides charge and discharge current reporting up to 320 A. The device includes features like external and internal cell balancing, an on-chip temperature sensor option, and support for external NTC thermistors.

 

Programmable protection features include over current, over temperature, and over/under voltage protection. The BQ78350DBTR-R1 also supports CC-CV charging, lifetime data logging, and can drive up to a 5-segment LED or LCD display for state-of-charge indication. It is available in a 30-TSSOP package suitable for surface mounting.

 

This part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer, and new designs should consider an alternate product. However, it remains available for existing customers.
