<1>MAX8903CETI+ is a dependable, highly efficient integrated power management integrated circuit (PMIC) specifically designed to serve as a battery charger. It utilizes a Synchronous Buck Converter, a multi-input solar LDOs, and both high and low voltage switches to deliver efficient power transfer solutions with minimal power losses over a wide range of input voltages. The MAX8903CETI+ features programmable current and voltage limits to ensure safe charging thresholds and keep the system protected. This device also offers thermal protection, turn-off/shutdown/block, and charging status detection. The main applied field for MAX8903CETI+ is to manage the majority of battery chemistries currently used in portable and stationary systems. This device is commonly used in personal electronics, wearable devices, smart speakers, portable medical devices, industrial system, and other applications. The working principle of MAX8903CETI+ involves two stages. The initial stage involves a special type of boost converter to ensure proper charging of the battery. This boost converter utilizes a capacitor to generate a voltage higher than that of the battery, ensuring the flow of charging current. The second stage of the charging cycle involves a synchronous buck converter, which maintains voltage levels and the flow of current. The buck converter also enables the system to operate in a low-power mode and extends the life of the battery. MAX8903CETI+ is designed to be highly reliable and efficient, capable of handling many of the current and future battery chemistries. It also offers thermal protection, turn-off/shutdown/block, and charging status detection. By utilizing a boost and buck converter design, it efficiently balances charge and discharge current, maximizes the efficiency of power transfer, and prevents voltage loss. This makes MAX8903CETI+ ideal for a variety of battery-dependent applications.
