MCP73833T-GPI/UN

Overview

The MCP73833T-GPI/UN is a single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within an input voltage range of 3.75 V to 6 V and provides a regulated output voltage of 4.2 V with a maximum output current capability of 1.2 A. The component is housed in a compact MSOP-10 surface-mount package, suitable for space-constrained designs. It supports programmable charging currents and includes thermal regulation features to ensure safe operation during the charging cycle.

Feature Summary

• Integrates complete charge management functions for single-cell lithium-based batteries
• Includes thermal regulation to reduce charging current when die temperature exceeds limits
• Indicates charge status via dedicated status pin
• Supports programmable charge termination current

Applications

• Portable electronic devices requiring single-cell lithium-ion or lithium-polymer battery charging
• Mobile communication equipment
• Medical instrumentation
• Industrial handheld tools

Procurement Notes

Verify the specific suffix GPI/UN against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with your PCB footprint for the MSOP-10 package. Cross-reference the datasheet for any recent manufacturing changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require a highly integrated solution for single-cell Li-Ion or Li-Po batteries. It is appropriate for applications needing precise charge termination and thermal protection without external MOSFETs. Consider the MSOP-10 package constraints and the 3.75 V to 6 V input voltage range relative to your system's power supply architecture.
