Battery Chargers Procurement Notes

Verify the specific suffix '2ATI' corresponds to the required 4.2 V output voltage and industrial temperature grade (-40°C to +85°C). Confirm the '/MC' designation aligns with the intended SOT-23-5 packaging requirements. Ensure compatibility with system ground references and check for any RoHS compliance documentation relevant to the manufacturing batch before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component for applications requiring a compact, low-cost solution for single-cell lithium battery charging. The SOT-23-5 package offers space efficiency compared to larger alternatives. Consider the 500 mA maximum current limit when sizing external components. Verify that the 6 V maximum input voltage accommodates the highest expected source voltage in the target application environment.

Battery Chargers Part Context

This part belongs to the MCP7383x family of charge management controllers from Microchip Technology. The series includes variants with different output voltages and packages, such as the MCP73831 and MCP73832. These controllers are designed to simplify battery charging circuitry by integrating essential protection and regulation features into a small footprint suitable for portable electronics.

Battery Chargers Replacement Considerations

Direct substitutes include other MCP73832 variants with compatible output voltages and packages, such as MCP73832T-2ACI/OT. Verify pinout compatibility and electrical specifications before substitution.
