MCP73832-3ACI/MC

Battery Chargers Overview

The MCP73832-3ACI/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 supports a maximum programmable charging current of 500mA. The device features a fixed 4.35V termination voltage, suitable for specific high-voltage lithium chemistry cells. It is housed in an 8-DFN (2x3) surface-mount package with exposed pad and functions reliably across an industrial 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-current charging capability allowing customization of the input current limit
• Fixed 4.35V regulation profile designed for specific high-voltage lithium cell chemistries
• Built-in thermal regulation circuitry that automatically reduces charging current to prevent overheating

Battery Chargers Applications

• Portable electronic devices requiring single-cell high-voltage lithium power sources
• Industrial control modules operating in extended temperature environments
• Medical instrumentation utilizing specialized lithium polymer battery packs
• Consumer electronics powered by 4.35V nominal lithium cells

Battery Chargers Procurement Notes

Verify the specific suffix '3ACI/MC' to confirm the 4.35V output variant, as other suffixes indicate different voltages. Ensure the 8-DFN footprint matches the PCB layout due to the exposed thermal pad requirement. Confirm RoHS compliance status through official Microchip documentation before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component when the application requires a 4.35V termination voltage rather than the standard 4.2V found in most lithium-ion cells. The 8-DFN package offers a compact solution for space-constrained designs. Consider the 500mA maximum current limit against the target battery capacity to determine appropriate charging times and thermal management needs.

Battery Chargers Part Context

This part belongs to the MCP73831/2 family of charge management controllers from Microchip Technology. While sharing core architecture with the MCP73831, the MCP73832 variant typically includes additional status indicators or pin configurations. The 'MC' suffix denotes the specific 8-DFN package type used in this configuration.

Battery Chargers Replacement Considerations

MCP73832T-3ACI/OT provides the same electrical characteristics in a SOT-23-5 package. MCP73832-2ACI/MC is a direct functional substitute but utilizes a 4.2V termination voltage instead of 4.35V.
