MCP73832T-2ACI/MC

Battery Chargers Overview

The MCP73832T-2ACI/MC is a single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within a supply voltage range of 3.75V to 6V and provides a regulated output voltage of 4.2V for the battery cell. The device supports a programmable constant charging current with a maximum capacity of 500mA. It utilizes an 8-DFN (2x3) surface-mount package, designated as SC-79A or 8-VFDFN with exposed pad, suitable for compact designs. The component functions reliably across an operating temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrated linear charge management controller optimized for single-cell lithium-ion and lithium-polymer batteries
• Programmable constant charging current capability allowing customization up to the maximum limit
• Includes thermal regulation feature to automatically reduce charging current during high junction temperatures
• Indicates charge status via dedicated status output pin

Battery Chargers Applications

• Portable consumer electronics requiring single-cell battery charging
• Medical devices utilizing lithium-based power sources
• Industrial handheld equipment and sensors
• IoT modules and wireless communication devices

Battery Chargers Procurement Notes

Verify the specific suffix 'MC' corresponds to the 8-DFN package configuration when sourcing. Confirm that the '2' in the part number indicates the 4.2V fixed output setting appropriate for standard lithium cells. Ensure compatibility with your PCB footprint for the 8-VFDFN exposed pad package. Check for RoHS compliance documentation if required by your manufacturing standards. Validate availability through authorized Microchip distributors to guarantee authenticity.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell Li-Ion/Polymer charging is required. The 8-DFN package offers a smaller footprint compared to SOT-23-5 variants like the MCP73832T-2DCI/OT. Choose this model over the MCP73831 series if integrated charge termination monitoring is needed rather than just timer-based termination. Consider the 500mA maximum current rating against your battery's C-rate requirements. Ensure the input voltage source can sustain the necessary headroom above the battery voltage.

Battery Chargers Part Context

This part belongs to the MCP73831/2 family of charge management controllers from Microchip. The MCP73832 variant specifically includes a charge status flag output, distinguishing it from the MCP73831 which lacks this feature. The 'T' suffix denotes tape-and-reel packaging, while 'MC' specifies the 8-DFN package type. This family is designed for cost-sensitive applications requiring reliable single-cell charging without external MOSFETs.

Battery Chargers Replacement Considerations

MCP73832T-2DCI/OT: Same electrical function but in SOT-23-5 package; requires PCB layout adjustment. MCP73832-2ACI/MC: Non-tape-and-reel version in tube packaging; suitable for prototyping. MCP73831T-2ACI/MC: Lacks charge status flag output; verify if status indication is critical.
