Power management integrated circuits (PMICs) are semiconductor-based integrated circuits that are widely used in industrial, automotive and consumer applications. With the development of integrated circuits, the application field of PMIC has been further expanded. In particular, the battery charger is widely used in electronic products, such as smartphones, tablets, digital cameras, and other portable devices. The LT1510IGN#PBF is a low dropout (LDO) battery charger PMIC used in portable devices. It is designed to charge single-cell Li-ion and Li-Polymer batteries in the portable applications. This paper will describe the application field and the working principle of the LT1510IGN#PBF battery charger.

The LT1510IGN#PBF is an ideal battery charger for mobile applications. It is a highly integrated device with enabling features to support fast and efficient charging of single-cell Li-ion and Li-Polymer batteries. This device combines high-efficiency buck converter with an LDO, which allows it to switch between multiple power sources to charge the battery. The operating input voltage range of LT1510IGN#PBF is from 4.95V to 10.5V, which makes it suitable for common 5V and 12V power supplies. This feature makes LT1510IGN#PBF an attractive solution for applications with multiple power sources, such as USB, AC-DC wall adapters and automotive applications. The device supports charge currents up to 800mA and has a programmable input current limit and battery saliency control, making it ideal for applications with stringent power requirements.

The LT1510IGN#PBF, as an advanced single-chip power management IC, integrates a buck regulator, linear regulator and power logic circuit. The buck switching regulator provides the high efficiency charging current, while the linear regulator is used to provide the low dropout voltage to the battery. The power logic circuit provides advanced safety features such as over-temperature protection, charge control, over-current protection, and battery detection.

The working principle of the LT1510IGN#PBF can be broken down into three basic stages. First, the power logic circuit detects the input source and activates the appropriate power path. Second, the buck switching regulator adjusts the charge current according to the required voltage and the desired charging speed. Third, the linear regulator provides a constant voltage to the battery at the end of the charging cycle. The battery temperature is monitored throughout the charging process and the charging current is adjusted accordingly to prevent over-heating of the battery. The device also has a programmable charge current limit, and a programmable battery saliency control that helps minimize the total power dissipation in the charging circuit.

The LT1510IGN#PBF provides an extremely compact, low power solution for mobile battery charging applications. It is well-suited for portable devices such as smartphones, tablets and digital cameras, which are highly dependent on shorter charging times, precise charging currents, and well-controlled battery temperatures. The device demonstrates improved power efficiency, enhanced reliability and improved battery lifespan, and therefore has become a popular charging solution for modern mobile devices.
