Instructions for Use

1. Power Supply Connection:

   • Connect the positive terminal of the battery to the V+ pin.
   • Connect the negative terminal of the battery to the V- pin.

2. Cell Connections:

   • For multi-cell configurations, connect the individual cell terminals to the corresponding cell balance pins (CELL1, CELL2, etc.).

3. Communication Interface:

   • Connect the SDA and SCL pins to the I2C or SMBus lines of your microcontroller or system.
   • Ensure that pull-up resistors are used on the SDA and SCL lines if not already provided by the system.

4. Protection Circuitry:

   • The BQ4013MA-85 includes built-in protection circuits for overcharge, overdischarge, overcurrent, short-circuit, and thermal protection.
   • No additional external protection components are required, but it is recommended to review the specific application requirements.

5. Thermal Management:

   • Ensure adequate heat dissipation by placing the BQ4013MA-85 on a PCB with sufficient copper area or using a heatsink if necessary.
   • Monitor the temperature during operation to ensure it stays within the operating range.

6. Programming and Configuration:

   • Use the I2C or SMBus interface to configure the BQ4013MA-85 according to your specific application needs.
   • Refer to the datasheet for detailed register maps and programming instructions.

7. Storage and Handling:

   • Store the BQ4013MA-85 in a dry, cool place away from direct sunlight.
   • Handle with care to avoid static discharge and physical damage.

8. Safety Precautions:

   • Always follow safety guidelines when handling lithium-ion batteries.
   • Do not exceed the maximum ratings specified in the datasheet.

For more detailed information, refer to the BQ4013MA-85 datasheet and application notes.
