AOZ9252DI

The AOZ9252DI are micro-power management integrated circuits (PMICs) used for battery management applications. The AOZ9252DI provide a range of integrated functions, including dual-phase voltage regulation, over-temperature and short-circuit protection, charge current monitoring, and dynamic power management. The AOZ9252DI offer significant power and area savings compared to discrete solutions, while providing additional protection and detail performance monitoring capabilities.

The AOZ9252DI are targeted at portable devices and consumer products such as smart phones and tablets. The integrated features provide the necessary protection for these sensitive components, and the reduced power consumption and size make them ideal for these applications. The AOZ9252DI can work with a wide range of battery chemistries such as Li-ion, LiFePO4, NiMH, and alkaline, and provide accurate and reliable operation over a wide range of operating temperatures.

The AOZ9252DI provide advanced functions such as cell balancing, charge cycle counting/monitoring, and temperature monitoring. The AOZ9252DI also provide a wide range of pre-programmed charging profiles, from basic to advanced, to ensure the best performance from the battery. The AOZ9252DI also provide diagnostic functions and cell protection to detect faults in the situation. The integrated protections and configurable options ensure the battery is not overcharged, discharged, or exposed to unsafe levels of current or voltage.

The AOZ9252DI integrate a wide range of features to make them simple to use and configure. They include a high-speed digital control core, high-voltage input power supply and internal power supply, real-time clock and low-frequency oscillator, and a set of communication bus interfaces. The AOZ9252DI also include an external N-channel MOSFETs which can be used to switch off the load during high-current peaks, protecting the device and reducing the power consumption.

The AOZ9252DI can also be protected against unexpected events. The device includes an internal temperature-sensing circuit that can shut off the load in case of an over-temperature event. It can also monitor the voltage and current of the battery and issue warning and/or reset the device if necessary. The AOZ9252DI can also detect a fault in the load, and can shut off the load in case of a short-circuit. This can prevent further damage or potential safety risks.

The AOZ9252DI enable developers to configure the device for maximum performance or safety, based on the application requirements. The device also provides a range of configurable parameters, such as charging/discharging current limits, charge termination voltage, temperature thresholds, and others. This allows the board designers to customize the device for their specific environment. The integrated protection and monitoring features of the AOZ9252DI help to ensure reliable operation and maximum protection for the application.
