MCP73833-GPI/UN

Overview

The MCP73833-GPI/UN 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 3.75 V to 6 V and provides a regulated output voltage of 4.2 V with an output current capability of 1.2 A. The device is housed in a 10-MSOP surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates complete charge management control for single-cell lithium batteries
• Includes thermal regulation to manage heat during high-current charging
• Supports programmable charge current settings

Applications

• Portable electronic devices requiring single-cell battery charging
• USB-powered battery charger designs
• Consumer electronics utilizing lithium-ion or lithium-polymer cells

Procurement Notes

Verify the specific suffix GPI against official Microchip documentation to confirm pinout and functional variations relative to other MCP73833 variants. Ensure compatibility with your PCB footprint, as the MSOP package requires precise soldering. Confirm moisture sensitivity levels and storage conditions prior to assembly to prevent component damage during reflow.

Selection Notes

Select this component when a compact solution for single-cell Li-Ion or Li-Po charging is required. The 1.2 A output current supports faster charging for higher capacity cells compared to lower-current alternatives. The wide input voltage range allows flexibility in power source selection, including standard USB ports.

Part Context

This part belongs to the MCP7383x family of charge management controllers designed for portable applications. These ICs are engineered to simplify battery charger design by integrating essential safety features and control logic into a small form factor, reducing the need for external components typically required in discrete charging solutions.

Replacement Considerations

Direct substitutes include other MCP73833 variants such as MCP73833-CNI/UN or MCP73833-AMI/MF, provided the package type matches the design requirements. Verify that any replacement maintains the same 10-MSOP footprint and electrical specifications to ensure board compatibility.
