PMIC - Battery Chargers come in a variety of choices, and the RT9480GQW is an excellent example of a quality-made one. It is a cost-effective dual-input, two-output power management integrated circuit (PMIC) with a wide range of battery charging capabilities. The RT9480GQW is specially designed to provide battery charging in the widest possible range of diverse operating conditions. It is well suited for applications such as dual-input laptops, multi-cell battery packs, medical devices and portable electronics.

The RT9480GQW application field is to manage lithium-ion and/or Li-polymer battery charging. It features a high-performance controller and range of power switching circuitry that provides simultaneous charging from two input sources and two outputs from the battery. This makes it extremely versatile and capable of charging many different types of battery packs with a suitable charge profile or charger. This makes it the ideal choice for medium to large-scale battery charging applications.

The RT9480GQW has been intelligently designed to provide fast, safe and reliable charging of battery packs. It offers the highest system utilization of a wide range of voltage levels, current ratings, and maximum charge levels. It also provides numerous options for controlling the charging current on each output, including charging time, charge termination conditions and charge safety/termination delay. It also offers monitoring functionality that allows the user to monitor battery voltage, current, temperature, and capacity.

In terms of working principle, the RT9480GQW operates on a multi-stage charging cycle. The first stage is a conditioning stage, where the battery\'s voltage and temperature levels are monitored to ensure the charging parameters are appropriate for the battery. In the second stage, the charging current is supplied to the battery and the charging profile can be adjusted depending on the battery\'s state. As part of this profile, the system also sets a custom charge termination condition, which can be set to prevent overcharging, or provide an early termination of the charging process.

The third stage of the charging cycle is the maintenance stage, where the system maintains the battery within a safe level at all times. Maintenance includes monitoring constant current levels and preventing the battery from exceeding its charge capacity or other parameters. Safety features such as current rate limiting, over temperature protection and cell balancing are also employed to protect the battery from any damage.

Overall, the RT9480GQW PMIC is a highly efficient and reliable charger option for battery applications. Its wide range of features and versatile charging capabilities make it suitable for a variety of applications, from single to multiple battery application. Additionally, its high level of safety features ensures maximum charging efficiency and reliability for your battery packs.
