MCP73864-I/ML is one of a number of power management integrated circuit (PMIC) components designed for battery charge applications. The MCP73864-I/ML is a Lithium-Ion/Polymer battery charge management controller with an integrated power MOSFET. The device is designed to operate with a wide range of Lithium-Ion and Lithium-Polymer battery colors to assure compatibility with most available battery packs. The device utilizes an integrated switch-mode charger architecture, using a high-frequency fixed frequency pulse width modulation (PWM) control loop. This architecture results in a highly efficient (typically > 90%) battery charging solution.

The MCP73864-I/ML features two charging control signals— one for charging and one for preconditioning of the battery. The charging behavior of the device is controlled by an internal charge controller which is programmed via external resistor dividers. The MCP73864-I/ML implements a constant Voltage/Constant Current charge profile and has the ability to program the current limit from 10mA to a full battery capacity of 4A. A precision temperature monitoring system is incorporated in the circuit to aid in temperature compensation. The device features integrated cell balancing of up to 4-cells, helping to insure battery pack safety and longevity.

The MCP73864-I/ML is well suited to any Lithium-Ion/Polymer battery charge management application. Key applications of the device include: battery management systems for mobile phones, tablets, PDAs, portable gaming units, and MP3 players, as well as for industrial and telecom applications.

The device is designed to operate with a wide range of Lithium-Ion and Lithium-Polymer battery colors to assure compatibility with most available battery packs. Depending on the application, a simple set of external resistors will configure the device for the required charge current and charge voltage settings. The device is also current-limited, meaning that it will protect the battery, cell stack, and system. The device is also integrated with thermal sense, under-voltage lockout, and over-voltage protection, offering robust and reliable protection across a variety of battery charge management applications.

The MCP73864-I/ML also features two independent programmable charge status output pins. These indications along with the thermal sense pins can be used in system monitor applications to help optimize performance and maximize the life of the battery. The MCP73864-I/ML also comes with a low shutdown current, further saving power and reducing the overall operating cost.

To summarize, the MCP73864-I/ML is an integrated high frequency switch-mode charger designed for Li-Ion battery packs from 10mA to 4A. The device also provides a precision temperature monitoring system and integrated cell balancing, making it well-suited for battery charge management applications. It offers robust protection against battery over-charge and under-voltage and comes with two programmable charge status output pins. The device also features a low operating current, making it an ideal choice for power management applications.
