Introduction

The MP26101DR-LF-P is a buck-boost charging controller, intended to be used as a battery charger in different applications. It is designed to switch mode, with a maximum switching frequency of 1.5Mhz and 95% efficiency. The device also includes many features such as temperature detection, thermal protection, battery fuse, etc. The device is also compliant with the international standards and has a wide range of operating temperature.

Application Field

The MP26101DR-LF-P is suitable for a wide range of applications, such as small power mobile applications, LED lighting and home appliance applications, and portable device charging. This device can be used for either Li-Ion battery charging or Nickel-Cadmium/Nickel-Metal Hybrid battery charging. This device can also be used for charging in various situations, such as normal/low power, high/slow charge, and standby charge.

Working Principle

The MP26101DR-LF-P works by switching its input voltage to the battery voltage. Once the battery voltage is reached, the device will switch to a constant voltage output, allowing the battery to charge at a stable rate. The device then switches to a constant current mode when the battery reaches full charge. It also includes a soft start circuit to minimize the inrush current at the start of the charging process.The MP26101DR-LF-P also features a special Dynamic Power Control (DPC) algorithm that monitors the temperature of the battery and adjusts the charging strategy in order to ensure that the battery is safely charged. The device also provides over-voltage, over-current and short-circuit protection.

Conclusion

The MP26101DR-LF-P is an advanced buck-boost switching charging controller intended to be used as a battery charger in different applications. It has a wide range of operating temperature and includes many features such as temperature detection, thermal protection, battery fuse, etc. The device works by switching its input voltage to the battery voltage and features a special Dynamic Power Control (DPC) algorithm that monitors the temperature of the battery and adjusts the charging strategy in order to ensure that the battery is safely charged.
