PMICs (Power Management Integrated Circuits) are essential components to various applications in most fields today.Currently, PMICs are mainly divided into eight major product lines, which are: battery chargers, DC-DC converters, motor drivers, LED drivers, LED controllers, micro-controllers, regulators and audio solutions. The main applications of these product lines include the following: power plants, telecommunications, medical, industrial control and automotive industries. In this article, the focus will be on the battery chargers category, looking closely at the MP26060EQ-LF-P model and its particular field of application and working principles.

The MP26060EQ-LF-P is a Li-ion/Li-pol charger IC that provides excellent thermal resistance, high performance and high reliability. It comes in an ultra-small FCQFN-8 package and its charging current can be set independently in a wide range of up to 1.5 A. It also has an array of safety features such as over-voltage detection, under-voltage detection, short circuit protection, thermal shutdown and charge timer infinity setting. The features make this model particularly suitable for Li-ion/ Li-pol battery charging applications in portable equipment such as compact electronic products, PDA/smart phones, MP3 players and digital cameras.

The working principle of the MP26060EQ-LF-P is based on the well known power supply design principle of constant-current/constant-voltage (CC/CV) switching. It starts by delivering a constant current during the fast charge phase of the battery. Once the voltage reaches its peak, it switches to the constant voltage phase. During this second phase, the current decreases until the battery is fully charged. The MP26060EQ-LF-P provides an automatic CE-on/CE-off termination feature to end the charging process when the current has dropped a certain amount below the fast-charge current. This model also has an adjustable charge termination current, allowing the fast charge current setting to be maximized for a shorter charging time. It has a built-in timer to prevent overcharging of Li-ion batteries allowing users to select an optimum charging time for their application.

In addition to these features, the MP26060EQ-LF-P has several other benefits including a low dropout voltage, low supply current and output current limit setting that make it ideal for space-constrained applications. Its soft start design prevents inrush currents and load transients, while its reverse polarity protection independently protects the charger and its output device. It also has a low profile design with a low profile size, optimal thermal performance and minimal total heat dissipation.

In conclusion, the MP26060EQ-LF-P is an ideal charger IC for a wide range of applications. It provides excellent thermal resistance and high performance and reliability, in addition to a wide range of features such as over-voltage and under-voltage detection, short circuit protection, thermal shutdown and charge timer infinity setting. The model’s power-supply design principle of constant-current/constant-voltage (CC/CV) switching ensures optimal charging of the Li-ion/ Li-pol batteries and also provides excellent thermal performance and low supply current. This makes it a great choice for continuous and reliable charging of battery packs in space-constrained applications.
