The MAX8895XEWA+T is a battery charger PMIC designed specifically for the ultra-low power operations and applications. The MAX8895XEWA+T is available in a 28-pin, 3mm x 3mm QFN package with an extended temperature range (-40°C to +85°C). The PMIC has various built-in features, such as fast charge and charge/discharge control which makes it suitable for applications requiring low power consumption and fast charging.

The MAX8895XEWA+T integrates an internal switching regulator that is capable of delivering up to 1.3A of maximum output current. The device also includes a precision charge controller, an integrated thermal protection circuitry and safety timers. These features enable the device to manage charging when connected to a wide range of battery types and chemistries, including Li-Ion, Lithium-Polymer and LiFePO4 cells.

The chargers feature a wide input voltage range of 2.6V to 5.5V. This makes them ideal for use with a variety of sources, including USB, AC adapter, DC adapter and others. They can also be controlled via an I2C or SMBus interface. Additionally, the MAX8895XEWA+T has a high-accuracy voltage control loop which helps ensure the desired output voltage is maintained. The devices also have an active power-good output to indicate when the charge is complete.

The MAX8895XEWA+T is ideal for applications requiring fast charging and long battery life. It is particularly suited for mobile applications such as active sensing, wearables, portable medical equipment, IoT devices and other applications. Additionally, the device is well suited for automotive and industrial applications, as it is capable of operating from cold-crank conditions.

The MAX8895XEWA+T’s working principle is simple. It first checks for a viable input voltage and then initializes the charging process. During the charge, the device monitors automatically the output voltage and current. Once the setcharging criteria are met, the device stops the charge cycle. A safety timer ensures that, if a fault ever occurs, the safety timer will shut off the charger, thus preventing any damage to the system.

In conclusion, the MAX8895XEWA+T is a powerful, efficient and cost-effective PMIC designed for battery charging operations. Its wide input voltage range, integrated switching regulator, precision charge controller and built-in safety features make it the perfect solution for powering mobile, automotive and industrial applications.
