It can be used for battery charging and management of single or multiple cells. It has high efficiency, low heat, wide input voltage range, and an adjustable output current.

Application Field

The MC33340DR2 is designed for power sources in mobile device applications. It is most suitable for operating with low-power Li-ion and Li-polymer batteries. It is used in power sources such as mobile phones, tablets, portable media players, dataloggers, and Navigators.

The MC33340DR2 is also used in applications that require sensing of the ambient temperature before commencing a charging operation. This feature makes it ideal for medical sensor applications that must measure and monitor the environmental conditions.

The MC33340DR2 chipset is used to control, monitor and protect the lithium-ion battery and can be used to monitor battery remaining capacity, battery temperature and short-circuit protection.

Working Principle

The MC33340DR2 is based on multiple protection and monitoring capabilities for Li-ion, Li-polymer, and other battery technologies. It provides real-time monitoring, lockout, protection, and diagnostics of the battery system.

The MC33340DR2 chipset consists of a low pass filter, charger controller, low dropout and charge current monitor. The low pass filter prevents AC power cord noise from disturbing the charging system. The charger controller consists of a control register and a timer for regulating charge and discharge constants such as voltage and current. The low dropout provides a fixed charging output voltage and a current monitor for detecting the presence of charge current.

To ensure maximum safety and efficiency, the MC33340DR2 chipset features adjustable high level safety features such as overvoltage, overcurrent and short circuit protection. These features provide the safeguard that any unintended events are monitored and controlled to ensure the performance and reliability of the device. It also features temperature sensing to detect any unexpected temperature changes and enable the appropriate charge cycle.

In summary, the MC33340DR2 is an efficient battery charging chipset with full protection that is suitable for applications that require low-power battery charging. It features adjustable input voltage range, adjustable output current, high level safety functions, temperature sensing, and real-time monitoring and diagnostics.
