PMIC - Battery Management

The BQ20Z65DBTR-R1 is a highly integrated battery management integrated circuit (IC) from Texas Instruments (TI). It is designed to be used in our most advanced battery packs to ensure smart charging, safe operation, and accurate monitoring of energy charge.

Application Field

The BQ20Z65DBTR-R1 is a highly integrated solution for battery management and is suitable for various applications such as notebook computers, cellular phones, personal digital assistants (PDAs), and portable media players. It offers comprehensive safety features, with a rich set of features that enable safe and efficient portable-device operation and charging.

The BQ20Z65DBTR-R1 is designed to automate and optimize the management of your battery by providing intelligent charge control algorithms, bringing together key battery-management functions such as monitoring, charging and thermal protection into a single IC. It also offers an array of analog and digital interfaces, and a wide range of reporting and power management options for an optimized battery-management system.

Working Principle

BQ20Z65DBTR-R1 is based on the common form of smart battery charging which is known as "charge termination," where the end of charge is determined by monitoring the battery voltage and current.

By monitoring the battery’s charging current, BQ20Z65DBTR-R1 is able to detect when the battery has been fully charged and shut off the charging process. It also provides charging current and voltage more accurately, which can improve battery life, as well as prevent overcharging.

Additionally, it provides sensing and reporting capabilities to enable the host system to monitor the state of the battery and the current charging. This helps ensure that the battery has adequate charge while protecting it from overcharging and other hazards.

For battery-pack safety, the BQ20Z65DBTR-R1 IC includes a low-voltage cutoff and over- and under-voltage protection. It also has a fault delays feature to monitor the battery and provide a delayed response to a detected fault condition.

To ensure efficient and safe charging, it also offers both constant-current/constant-voltage (CC/CV) and pulse-charging control. Additionally, it has an internal 40 mA detect circuit for determining when the battery is connected and requires charging.

Conclusion

In conclusion, the BQ20Z65DBTR-R1 is a highly integrated PMIC designed for battery management and is suitable for various applications. It features comprehensive safety features, a wide range of reporting and power management options, and both CC/CV and pulse-charging control. All of these features help ensure safe and efficient portable-device operation and charging.
