The MAX77818EWZ+T is a member of a family of Power Management ICs (PMICs) designed for providing battery charger functions. Built to maximize real estate efficiency and modern 3D integration, battery chargers under the MAX77818EWZ+T line are usually used in applications with limited space and cost constraints. With UFS power management and charging features, these chargers are ideal for applications such as wearables, smartphones, and tablets.

The innovative charging design of the MAX77818EWZ+T combines high current charging and low quiescent current operation to eliminate wait times and minimize battery drain. The design of the MAX77818EWZ+T enables the battery to charge in one of the shortest times available – from empty to full in as little as 15 minutes with little or no heat buildup. With its smart charging methods and low impedance sensing, it can maximise the charging efficiency by effectively balancing battery temperature and capacity increase.

The main feature of the MAX77818EWZ+T is its ability to monitor and maintain battery health while charging. It can detect the battery’s current temperature and modify the charge current accordingly to maximum charging efficiency. It also monitors and terminates charging when it detects a danger of overcharging or overly high charging temperature. The charger also supports trickle charge, offering a full charge without the need for frequent charging cycles.

The MAX77818EWZ+T’s efficient internal power-supply switch allows it to provide high power and current capacity with minimal losses. This allows for fast and efficient charging of most portable devices, even during peak transient current drawing. The chip also supports a wide range of power inputs, ranging from USB type C power to additional input for USB type A power.

The MAX77818EWZ+T comes with an advanced, proprietary power management algorithm, which allows for automatic power on/off. It also provides up to 1.25A DC power and up to 2A of USB power. It can also be configured to adjust the current supplying depending on the state of the battery. This feature ensures that the current supplying charges the battery in an optimized manner, preventing any overcharging or deep discharging. Thanks to its fast and intelligent charging control, the MAX77818EWZ+T can also include useful features such as under voltage, over voltage, over temperature, charge status, and battery temperature protection.

Overall, the features of the MAX77818EWZ+T make it a great choice for battery charging applications that require high power and current capacity, efficient user power management, and intelligent charging control. It is highly suitable for applications like wearables, smartphones, and tablets as it is versatile, cost-effective, and provides maximum charging efficiency and safety in all conditions.
