Battery management is an essential part in many consumer electronics, such as cell phones, laptops, and tablets. Battery systems are constantly being developed to extend their industry applications and improve performance. The BQ26500PWRG4 is an advanced power management IC (PMIC) designed for use in portable Li-Ion and Li-Polymer battery-powered applications. It is capable of managing battery charging and protection both in the charger and in the battery pack. This article will discuss the application fields and working principles of the BQ26500PWRG4.

The BQ26500PWRG4 is an adjustable power management IC which offers a wide range of features including high integration, excellent system accuracy, and cost-effective solution.

The BQ26500PWRG4 can be used to manage and charge both single cell and multi-cell Lithium-ion batteries. It also has a built-in adapter for long-term battery protection. In addition, the BQ26500PWRG4 is capable of monitoring cell parameters such as the voltage, current and temperature of the battery at all times while providing protection measures against over-voltage, over-charge, over-discharge and short-circuits. It also provides a complete control system for the battery pack including charge and protection functions.

The BQ26500PWRG4 is mainly used in the applications of mobile phones, tablets, and laptops, which need long-term standby or asynchronous charging. It can be used for charging through the adapter, charging through the USB port, and simultaneous charging. Besides, it also applies to wireless charging and battery monitoring.

The BQ26500PWRG4 working principle is relatively simple and straightforward. First, the power management module receives power from a DC power supply, typically a wall adapter or the device\'s USB port. This power is then distributed by the PMIC to supply the device with the appropriate amount of power. Then the PMIC monitors the battery\'s charge and discharge rate, controlling the amount of power output to the battery and device, and will protect the battery from over-charge, over-discharge, and short-circuiting. The BQ26500PWRG4 also provides a power saving mode, which will reduce the power output to the device when it is not actively being used.

The BQ26500PWRG4 is an advanced power management IC offering high-performance and cost-effective solutions for portable Li-Ion and Li-Polymer battery-powered applications. It provides a complete control system for the battery pack and can be used for the charging and protection of single cell and multi-cell lithium-ion batteries. It also offers a wide range of features including excellent system accuracy, integrated adapter protection, and power saving mode. The BQ26500PWRG4 is mainly used in mobile phones, tablets, and laptops providing long-term standby or asynchronous charging, USB port charging, and wireless charging.
