MCP73833T-NVI/UN

Overview

The MCP73833T-NVI/UN is a standalone linear charge management controller for single-cell lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 3.75 V to 6 V, delivering a regulated output current of 1.2 A and a precise charging voltage of 4.2 V. The device is housed in a compact MSOP-10 package and supports surface mount installation. It functions reliably across an extended temperature range from -40°C to +85°C, ensuring stable performance in various electronic applications.

Feature Summary

• Autonomous source selection between AC adapter and USB port inputs
• Integrated thermal regulation to manage heat during high-current charging
• Status indicator output for monitoring charge completion

Applications

• Portable consumer electronics requiring Li-Ion or Li-Polymer battery charging
• USB-powered devices with integrated power management
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'NVI' confirms the MSOP-10 package and '-40C to +85C' temperature rating. Confirm 'T' indicates tape-and-reel packaging if required for automated assembly. Cross-reference the manufacturer part number with official Microchip documentation to ensure compatibility with your system's voltage and current requirements before procurement.

Selection Notes

Select this component when a standalone solution for single-cell lithium batteries is required without external MOSFETs. It is suitable for designs needing autonomous input switching and thermal protection. Ensure the application voltage does not exceed the 6 V maximum input limit. Consider the MSOP-10 footprint constraints during PCB layout planning.

Part Context

This component belongs to the MCP7383x family of charge management controllers. It shares functional similarities with other models like the MCP73833T-FCI/UN but differs in package type and temperature grade. The NVI suffix specifically denotes the MSOP-10 package variant designed for space-constrained applications.

Replacement Considerations

The MCP73833T-FCI/UN serves as a direct alternative, offering identical electrical characteristics but in a different package configuration. Verify pinout compatibility and thermal performance differences when substituting.
