PMIC – Battery Chargers are a highly specialized type of circuit which are used to convert energy from a power source, into a form of energy which is suitable for charging batteries. The AUR9807DSGD is a type of PMIC – Battery Charger which is designed for charging NiMH and NiCd batteries. This article will discuss the application field and working principle of the AUR9807DSGD.

The AUR9807DSGD is most commonly used in portable devices, such as digital cameras and cell phones. This type of PMIC – Battery Charger is well suited to these applications because it provides a high level of control and efficiency, as well as a low cost solution. The AUR9807DSGD has a wide range of features which make it an ideal choice when it comes to charging NiMH and NiCd batteries.

The AUR9807DSGD is designed to provide an output voltage range of 3.2 to 3.3V, with up to 4.2A of output current. It is equipped with a step-down converter which allows it to provide a consistent output voltage, regardless of the battery type. The step-down converter also allows the AUR9807DSGD to provide a stable charging rate for the batteries, which ensures that the batteries are charged quickly and safely. The AUR9807DSGD has a wide operating temperature range of -40 to +105°C, so it is well suited to use in portable devices where temperature control is important.

The main advantage of the AUR9807DSGD is its ability to provide an adaptive charging protocol which is tailored to the specific application. The AUR9807DSGD is capable of providing a fast charging current (up to 4.2A), as well as a slow charging current (0.7A) depending on the type of battery being charged. This adaptive charging protocol ensures that the batteries are charged safely, quickly and efficiently. In addition, the AUR9807DSGD is equipped with a range of protection features which help to protect the batteries from damage, as well as reduce power waste.

The AUR9807DSGD is powered by an integrated Quasi-Resonant (QR) controller which reduces power consumption and EMI (electromagnetic interference). The integrated QR controller also helps to improve the efficiency of the charging process. In addition, the AUR9807DSGD has a range of additional features including an adjustable timer and a foolproof input current monitoring circuit which help to provide more accurate control and operation of the charger.

The working principle of the AUR9807DSGD is based on the use of an inductor-diode pair. The inductor-diode pair creates a magnetic field which is used to efficiently transfer power from the power source, to the output terminals where it is then used to charge the batteries. This process is known as ‘inductor-capacitor coupling’, and it is a highly efficient way of transferring and storing energy.

In conclusion, the AUR9807DSGD is a highly efficient PMIC – Battery Charger which is designed for use in portable devices. It is capable of providing a wide range of features which ensure that the batteries are charged quickly, safely and efficiently. The AUR9807DSGD is based on the use of an inductor-diode pair, which provides an efficient and reliable way of transferring and storing energy. This type of PMIC – Battery Charger is the perfect choice for charging NiMH and NiCd batteries in portable devices.
