Multi-cell battery manager unit with integrated charging, fuel monitoring, authentication and protection functions

TIDA-00553

Overview

The Texas Instruments (TI) bq40z60 device is a battery pack manager that integrates battery charge control output, fuel monitoring and protection functions to enable fully autonomous operation of 2- to 4-cell Li-ion and Li-polymer battery packs. This architecture enables internal communication between the gas-monitoring processor and the battery charger controller to optimize charge based on external load conditions and power path source management during system load transients and adapter current limits. The charging current efficiency is different for different power delivery external components such as NFETs, inductors and sense resistors.

characteristic

• Fully integrated meter, protector and charger for 2 to 4-cell Li-ion or Li-polymer batteries
• Integrated NVDC battery charger with input voltage range from 2.5V to 25V
• Impedance Track technology
• Integrated SHA-1 authentication
• This circuit design has been tested and includes an orderable EVM, user guide and evaluation software.
