The MCP73833T-CNI/MF is an advanced battery charging control circuit from Microchip Technology Inc. targeted for use in single-cell Li-Ion and Li-Polymer battery-powered systems. The circuit provides several features that enable simple and efficient integration, including programmable charge current, automatic charge termination, charge status indication pins and over voltage safety, among others. More specifically, the MCP73833T-CNI/MF was designed to provide the proper charge for Li-Ion/Li-Polymer batteries, with a total charge time of 4 hours or less at room temperature.

PMIC - Battery Chargers, of which the MCP73833T-CNI/MF is a member, are designed to provide the correct charge current, charge voltage, and charge termination voltage required to maintain optimal performance, safety, and life of a Li-Ion/Li-Polymer battery pack. There are several parameters that govern this type of charging circuit, including charge current, charge voltage, charge termination voltage, and battery temperature. By controlling these settings, PMIC - Battery Chargers ensure the battery pack is recharged in the safest and most efficient manner possible.

The MCP73833T-CNI/MF battery charger includes an on-board charge controller that applies power to the battery through three distinct charging stages. In the first stage, known as the Constant Current (CC) phase, the charge current is ramped up from zero as the battery voltage increases until it reaches the preset maximum current limit. The controlled charging current is maintained at a constant level within the limits prescribed by the design parameters until the battery voltage reaches the predetermined charge termination voltage.

The MCP73833T-CNI/MF also includes a Trickle Charge (TC) phase which maintains the battery voltage at full capacity by adding a low-level current at the charge termination voltage. This period of charging is triggered automatically when the voltage drops below the predetermined termination voltage. The TC phase will terminate when the battery voltage reaches full charge and the charge end terminal is asserted.

In order to ensure safe and efficient charging, the MCP73833T-CNI/MF uses an internal over voltage protection (OVP) circuit to detect when the battery voltage has exceeded the system specification. When it detects an over voltage condition, the OVP circuit will automatically suspend charging until the voltage has fallen to a safe level before resuming the charging cycle. This feature helps to minimize the risk of battery damage due to overvoltage.

The MCP73833T-CNI/MF includes a Charge Status Output (CSO) signal which indicates when the battery is being charged, when a full charge has been reached, and when a fault condition has been detected. This signal provides a convenient way for system designers to monitor the battery charging process and the current state of the battery.

The MCP73833T-CNI/MF is a feature-rich battery charging control circuit that provides system integrators and designers with an easy-to-use solution for Li-Ion and Li-Polymer battery systems. The on-board charge controller makes it easy to set the desired charge current, charge termination voltage, and overvoltage limits to ensure safe and efficient charging of the battery. The built-in CSO signal provides real-time feedback about the charge state and Fault conditions for added safety and monitoring. All in all, the MCP73833T-CNI/MF from Microchip Technology Inc. is an exceptional pick for Li-Ion and Li-Polymer battery-powered projects.
