MCP73837-NVI/MF

Battery Chargers Overview

The MCP73837-NVI/MF is a standalone charge management controller for single-cell lithium-ion and lithium-polymer batteries. It features an integrated power path manager that autonomously selects between AC adapter and USB port inputs, prioritizing system power while charging the battery. The device supports input voltages from 3.75 V to 6 V and delivers up to 1.2 A output current with a regulated 4.2 V output voltage. It operates within a temperature range of -40°C to +85°C and is housed in a DFN-10 package.

Battery Chargers Feature Summary

• Autonomous source selection between AC adapter and USB port without external control logic
• Integrated power path management for simultaneous system operation and battery charging
• Supports high-current charging profiles up to 1.2 A from AC sources
• Compatible with standard lithium-ion and lithium-polymer battery chemistries

Battery Chargers Applications

• Portable consumer electronics requiring dual-input power flexibility
• USB-powered devices needing automatic source switching
• Battery-operated systems with AC adapter backup capabilities
• Mobile communication devices with integrated power management

Battery Chargers Procurement Notes

Verify the specific suffix 'NVI' against Microchip's official datasheet to confirm pinout configuration and electrical characteristics match your design requirements. Ensure the DFN-10 package dimensions align with your PCB layout constraints. Confirm thermal performance specifications for your intended operating environment before finalizing procurement decisions.

Battery Chargers Selection Notes

Choose this component when autonomous input switching between USB and AC adapters is required without microcontroller intervention. It is suitable for designs needing high charging currents up to 1.2 A while maintaining system power integrity. Consider the DFN-10 package size and thermal dissipation capabilities relative to your application's space and heat management constraints.

Battery Chargers Part Context

This part belongs to the MCP7383x series of charge management controllers designed for portable applications. It complements other variants like the MCP73837-FJI/MF by offering specific packaging or feature configurations within the same functional family. The series addresses the need for efficient, compact power solutions for single-cell lithium batteries in modern electronic devices.

Battery Chargers Replacement Considerations

Direct substitutes include other MCP73837 variants such as MCP73837-FJI/MF, provided the package and pinout compatibility are verified. Cross-reference with MCP73838 models if different packaging options are acceptable. Always validate electrical parameters and thermal characteristics against the original specification sheet.
