MCP73830LT-0BCI/MYY

Battery Chargers Overview

The MCP73830LT-0BCI/MYY is a linear charge management controller designed for single-cell lithium-ion and lithium-polymer batteries. It integrates a full-featured Li-Ion/Li-Pol battery charger with power-path management, eliminating the need for external sense resistors. The device supports input voltages from 4.25V to 13V and provides programmable charge current up to 1A. It features thermal regulation to reduce charge current when die temperature exceeds safe limits, ensuring reliable operation in high-temperature environments without requiring an external thermistor.

Battery Chargers Feature Summary

• Integrates complete Li-Ion/Li-Pol charging algorithm including constant-current/constant-voltage termination and recharge capability
• Includes internal power-path manager for system load prioritization during input supply failure
• Features thermal regulation that automatically reduces charge current based on die temperature

Battery Chargers Applications

• Portable consumer electronics such as MP3 players and digital cameras
• Handheld medical devices requiring compact battery management
• Industrial handheld instruments and data loggers

Battery Chargers Procurement Notes

Verify the suffix '0BCI/MYY' corresponds to the specific tape-and-reel packaging and temperature grade indicated by Microchip. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure the ordering part number matches the exact package type (SOT-23-5) and electrical specifications required for the design.

Battery Chargers Selection Notes

Select this component when a small SOT-23-5 footprint is required for single-cell lithium battery charging. It is suitable for applications needing integrated thermal regulation without external temperature sensing components. Compare against other MCP7383x variants if higher output currents or different package options are necessary for the specific application constraints.

Battery Chargers Part Context

This part belongs to the MCP7383x family of charge management controllers from Microchip Technology. The family is characterized by its ability to manage single-cell lithium batteries with minimal external component count. The MCP73830 variant specifically focuses on providing a cost-effective solution with integrated thermal protection for space-constrained portable designs.

Battery Chargers Replacement Considerations

Direct replacements within the same family include MCP73830T-0BCI/MYY for reel packaging. Other compatible parts in the series include MCP73831 and MCP73832, which offer similar functionality but may differ in package size or specific feature sets like USB detection capabilities.
