MCP73831T-2ACI/MC Typical application Circuitry

MCP73831T-2ACI MC

The MCP73831T-2ACI/MC is a miniature single-cell, fully integrated lithium-ion/lithium-polymer charge management controller. It's designed for charging from a USB port or a dedicated charger with minimal external components, making it ideal for portable applications.

Application Scenarios

The MCP73831T-2ACI/MC is commonly used in:

- Portable Devices: Such as wearable technology, fitness trackers, and Bluetooth earpieces.

- Medical Devices: These comprise compact, recharging devices such as digital thermometers and blood glucose monitors.

- Consumer Electronics: This category includes tiny, portable gadgets like PDAs and portable speakers.

Important Elements The MCP73831T-2ACI/MC provides a number of important functions.

- Charge Regulation: Offers a configurable preconditioning and charge termination charge methodology with constant current/constant voltage.

- Charge Current Control: Variable charge current from 15 mA to 500 mA.

- Voltage Regulation: Fixed voltage regulation options available, with the MCP73831T-2ACI/MC variant typically set to 4.2V, suitable for Li-Ion batteries.

- Status Output: Indicates charging activity and completion via a status output pin.

Detailed Circuit Connection Example: Portable Bluetooth Speaker Battery Charging

In a portable Bluetooth speaker application using the MCP73831T-2ACI/MC, consider the following detailed circuit connections:

- Power Input (VDD Pin): Connect a 5V power supply, typically from a USB port, to the VDD pin of the MCP73831T-2ACI/MC. This pin supplies power to the chip and the battery charging circuit.

- Battery Connection (Vbat Pin): Connect the positive terminal of the lithium-ion battery directly to the Vbat pin. This pin is the output of the charge management controller and provides the charging current to the battery.

- Ground Connection (GND Pin): Connect the ground pin of the MCP73831T-2ACI/MC to the system ground. It is also necessary to connect the battery's negative wire to this common ground.

- Programming resistor for PROG pins: Attach a resistor between the PROG pin and ground to change the charging current. The value of this resistor determines the magnitude of the charge current as per the datasheet's specifications.

- Status Indicator (STAT Pin): Connect an LED (with a current-limiting resistor) or directly to a microcontroller pin through the STAT pin to indicate the charging status. When charging, the STAT pin can be driven low, and it will be high impedance when the charge cycle is complete.

Design Considerations

When integrating the MCP73831T-2ACI/MC into a circuit, several factors should be taken into account:

- Power Source Compatibility: Ensure the power source can provide sufficient current at 5V to meet the charging requirements and any additional system load.

- Thermal Management: Pay attention to the thermal aspects, especially if charging at higher currents. The MCP73831T-2ACI/MC may require thermal relief in the PCB design to dissipate heat efficiently.

- Charge Current Setting: Choose the PROG resistor value carefully to match the battery's charge current specification, avoiding overcharging or undercharging.

- Battery Chemistry: Ensure the battery chemistry is compatible with the charge management provided by the MCP73831T-2ACI/MC, which is optimized for lithium-ion and lithium-polymer batteries.

By carefully addressing these design considerations and following the detailed connection guidelines, the MCP73831T-2ACI/MC can be effectively utilized in a portable Bluetooth speaker application, providing a compact and efficient charging solution for the device's lithium-ion battery.
