.1. Introduction to PMIC - Battery ChargersPower management integrated circuits (PMICs) are electronic components designed to manage and control the power supply of electronic systems. PMICs are widely used in mobile phones, laptops and other portable electronic devices. Battery chargers are one of the most important categories of PMICs, as they are responsible for charging lithium-ion, nickel–metal hydride and other types of batteries.2. Overview of the MAX1879EUA+T.The MAX1879EUA+T is a high–efficiency step-down converters for lithium–ion battery charging applications. It supports a broad range of input voltages from 4.3V to 28V, making it suitable for automotive, industrial, telecom and other DC or AC applications. The device can provides load currents up to 5A with high efficiency. In addition, it is equipped with safety features to protect against short circuits, peak current limits, thermal shutdown and other protections.3. Application Field of the MAX1879EUA+TThe MAX1879EUA+T offers flexible configuration and a range of features, making it suitable for a wide range of applications. It can be used in automotive battery chargers, machine tools and other industrial equipment, power supplies, solar energy applications such as battery and energy storage systems, telecommunication systems, and embedded computer systems.4. Working Principle of the MAX1879EUA+TThe MAX1879EUA+T is a synchronous step-down DC/DC converter. It utilizes switch-mode power conversion, which allows the device to maintain high efficiency over a wide range of load conditions. The device is supplied with a voltage reference and features a synchronous rectifier, allowing the converter to operate in continuous conduction mode. This improves efficiency and reduces output ripple.The device features an internal linear regulator to provide constant current charging when the battery’s voltage reaches a pre-set threshold. The linear regulator also provides voltage control and ensures a soft-start. This reduces inrush current, protects the application from overshoot, and prevents power surges.The device includes an adjustable voltage monitor to ensure overvoltage protection and an adjustable current limit to protect the battery from overcharging. In addition, it includes a temperature monitor which can be used to set a temperature limit. When the temperature exceeds the limit, the device will enter thermal shutdown mode.5. ConclusionThe MAX1879EUA+T is a high–efficiency step-down converters for lithium–ion battery charging applications. It offers flexible configuration and a range of features, making it suitable for a wide range of applications such as automotive, industrial, telecom and solar energy. It utilizes modern switch-mode power conversion technology and is equipped with safety features to protect against short circuits, peak current limits, thermal shutdown and other protections.
