BQ20Z95EVM-001

What is BQ20Z95EVM-001?

The BQ20Z95EVM-001 is an Evaluation and Demonstration Board and Kit from Texas Instruments (TI) designed for applications that require sophisticated battery pack management. It is a high-performance, programmable and fully-integrated protection, monitoring, and charging solution that ensures maximum longevity and performance of battery packs used in applications such as portable multimedia players, digital cameras, camcorders, and other consumer portable electronics.

Application Fields

The BQ20Z95EVM-001 evaluation board is designed for evaluation and demonstration of the BQ20Z95 power path/fuel gauge IC for portable applications. It is an ideal tool for developing and debugging solutions that require management of lithium battery packs. This device features a programmable charge control, fuel gauge, and online monitoring, all of which help ensure high efficiency, long lifetime, and maximum safety of battery packs.

Working Principle

The BQ20Z95EVM-001 works in conjunction with the BQ20Z95 IC, which contains three main components: a linear charge controller, a fuel gauge, and an over-voltage protection circuit. The charge controller implements a programmable charge algorithm with accuracy up to ±2%. This allows charging of lithium battery packs with controlled current and voltage, protecting the battery pack from overcharging or discharging. The fuel gauge continuously measures the battery’s state-of-charge and state-of-health, and provides an automated power path system to supplement the battery’s charge when needed. Finally, the over-voltage protection circuit protects the system against potential hazards while charging or discharging battery packs.

Conclusion

The BQ20Z95EVM-001 is an ideal tool for developing and debugging solutions that require management of lithium battery packs. It features a programmable charge control, fuel gauge, and online monitoring, all of which help to ensure high efficiency, long lifetime, and maximum safety of battery packs. It is an Evaluation and Demonstration Board and Kit from Texas Instruments designed specifically for applications that require sophisticated battery pack management.
