TIDA-00883

1 to 4 Series Cell Li-Ion Battery Pack Manager Reference Design

TIDA-00883

Overview

The Texas Instruments bq40z50-R1 device is a Battery Pack Manager that integrates gas gauging, and protection for completely autonomous operation of 1-series to 4-series cell Li-Ion and Li-Polymer battery packs. The architecture enables communication between the fuel gauging processor and an enternal battery charger controller through SMBus broadcast commands.

Features

Fully Integrated gauge, protector and charger to support 1 to 4-Series Li-Ion or Li-Polymer cells
2nd Level Protector provides Over Voltage Protection and an integrated 3.3V LDO Regulator
Impedance Track Technology
Integrated SHA-1 Authentication
This circuit design is tested and includes orderable EVM, User's Guide, and evaluation software.
