Introduction

Battery management, or BMS, is the process of managing the lifespan, health, performance, and safety of a system’s battery. The battery management circuit (or PMIC) is a key component of the BMS. BQ27510DRZR-G3 is one such example of battery management circuits that provide design engineers with robust protection and advanced features for lithium rechargeable batteries. This application note explains the details about BQ27510DRZR-G3 and its working principles.

What is BQ27510DRZR-G3?

BQ27510DRZR-G3 is a low-power battery management integrated circuit with advanced features designed for safety and long system life. This PMIC is designed to minimize the battery consumption rate, minimize system noise, and extend the service life of lithium rechargeable batteries. It manages a Li-ion/ LiFePO4/ Li-SOCL2 battery stack and provides accurate measurement for the cell voltage. BQ27510DRZR-G3 integrates a battery gas gauge, safety circuit, and cell protection architecture. It has a fast-charging algorithm, fuel gauge, temperature sensor and overdischarge protection that guarantee safety. This IC requires very low standby and active power consumption, and has a wide operating temperature range of -40 to +85°C.

Application Field of BQ27510DRZR-G3

BQ27510DRZR-G3 can be used in many different kind of battery-based systems such as electric vehicles (EVs), high performance medical and industrial systems, and automotive and home appliances. BQ27510DRZR-G3 is optimized for high safety and system performance in EVs. It helps identify weak cells, activate battery protection when needed, and monitor real-time energy status. This IC enables over-voltage protection and low temperature protection to protect cell voltage from reaching dangerous levels. It can also protect the battery pack from temperature extremes and fire hazard. In medical and industrial systems, BQ27510DRZR-G3’s accurate measurements enable more precise capacity estimation and reliable battery current monitoring. This IC is also well suited for home appliances and automotive systems. It can be used for mobile phone chargers, uninterruptible power supplies (UPS), laptop batteries and other battery powered applications. It also has ±1% accuracy for real-time battery stack/cell level sensing.

Working Principle of BQ27510DRZR-G3

BQ27510DRZR-G3 is designed to minimize the power consumption of battery packs while increasing the lifespan and safety of the system. It uses an accurate voltage sensing mechanism to measure cell voltage and accurately gauge state-of-charge (SOC) and state-of-health (SOH) of battery packs. BQ27510DRZR-G3 also features an internal temperature sensor as well as overcharge/ overdischarge protection schemes to monitor battery pack temperature. The battery\'s state-of-charge can be accurately measured using the measured voltage, current and temperature. The IC takes into account the system temperature and determines the battery pack\'s capacity at any given time. BQ27510DRZR-G3 also incorporates an undervoltage lockout scheme that prevents the system from operating when the battery voltage is too low. This PMIC also offers complete protection for lithium-ion battery packs. It uses an integrated Coulomb counter for internal capacity measurement and monitors the current going into or out of the battery. This IC can detect a short circuit event and open the system’s control loop for protection. BQ27510DRZR-G3 also provides open circuit protection when an unusual voltage pattern is detected. It also prevents the battery from being over-heated or damaged due to long-term charging.

Conclusion

The BQ27510DRZR-G3 battery management integrated circuit is designed to provide design engineers with robust protection and advanced features for their lithium rechargeable batteries. It has low standby and active power consumption and wide operating temperature range. This IC can provide protection in medical and industrial systems, EVs, home appliances, and automotive systems. It accurately gauges the battery pack’s state-of-charge and state-of-health, and also offers protection schemes such as overcharge/overdischarge protection, overvoltage protection and low temperature protection. BQ27510DRZR-G3 is an excellent choice for comprehensive battery management for any application.
