BQ2085DBT-V1P2 Application Field and Working Principle

PMIC (Power Management Integrated Circuits) are specialized computer chips designed to manage power for digital circuits. PMICs have become an essential part of modern electronic designs, and the BQ2085DBT-V1P2 stands out as an especially desirable choice due to its ability to support industry-leading single-cell Li-Ion battery protection and charging applications. This BQ2085DBT-V1P2 uses an integrated register map to manage a wide range of system power needs, tailored specifically to the application’s requirement. This document outlines the application field and working principle of BQ2085DBT-V1P2.

Application Field

The BQ2085DBT-V1P2 is designed for low power consumption and high performance for single-cell Li-Ion battery protection. It offers superior battery capacity estimation and power consumption monitoring capabilities. It also provides support for trickle charge, minimal charge, top-off charge, peak current, constant current and constant voltage charging. For applications where reliable battery protection is a must, such as medical devices and telematics, the BQ2085DBT-V1P2 is the optimal choice.

The BQ2085DBT-V1P2 can support a variety of flexible charging profiles and system power needs, including USB and AC adapter charging, sleep and deep sleep modes, and wake-up/system reset on over-voltage/under-voltage thresholds. In addition, this device also offers comprehensive safety functions, including over-current protection and over-temperature protection, to ensure the safety of your system.

Working Principle

The BQ2085DBT-V1P2 leverages a state-of-the-art, integrated I2C-compliant register map to control multiple power-modes. The raw AHM (Accumulated Height Monitor) is used to measure and calculate total charge, with a resolution of 44.7 mAh/SOC (state of charge) or 1.4 Ah/C (capacity). The current/voltage sense, in conjunction with the AHM, is used to accurately measure the battery power level, which helps maintain an optimal charge-rate. The integrated register map also supports frequency/pulse width modulation (PWM) as well as pulse frequency modulation (PFM) control of the power supply to minimize power consumption in low-power application scenarios.

The BQ2085DBT-V1P2 also features a wide range of safety features, ensuring that the battery is monitored and protected from unexpected voltage spikes, short-circuits, and over-currents. This device provides a slew of system health-monitoring features, such as temperature and current monitoring, to ensure system and battery health. Finally, the BQ2085DBT-V1P2 uses a precision operating voltage comparator to detect voltage anomalies arising from low-voltage/high-voltage/short-circuit conditions and to immediately shut down the power supply.

Conclusion

The BQ2085DBT-V1P2 is a single-cell Li-Ion protection and charging PMIC that is suitable for a wide range of applications, such as medical devices and telematics. Its integrated register map allows for easy control of system power needs, and its wide range of safety features provides reliable battery protection and system health monitoring.
