LV5117V-MPB-H

Overview

The LV5117V-MPB-H is a single-cell lithium-ion battery charger integrated circuit manufactured by Sanyo Denki, now part of Panasonic. This CMOS-based device is designed for portable applications requiring efficient power management. It integrates charge control logic and power MOSFETs to manage the charging cycle for a single cell. The component supports standard charging profiles including constant current and constant voltage phases with thermal regulation capabilities.

Feature Summary

• Integrates charge control logic and power MOSFETs for a compact solution
• Supports full-temperature constant-current/constant-voltage charging profile
• Includes automatic recharge function triggered when voltage drops below threshold

Applications

• Portable electronic devices
• Mobile communication equipment
• Digital cameras

Procurement Notes

Verify the manufacturer origin as Sanyo Denki or Panasonic, noting corporate acquisitions. Confirm the package type matches the MPB designation. Check for obsolescence status as some listings indicate end-of-life conditions. Ensure datasheet versions align with specific suffix requirements for temperature ranges or packaging variations.

Selection Notes

Select this IC for single-cell lithium-ion applications requiring an integrated solution without external pass transistors. Consider the operating temperature range and input voltage specifications relative to the system design. Evaluate the need for thermal regulation features if high-current charging is required in enclosed spaces.

Part Context

This component belongs to the LV5117 series of battery chargers. It is categorized under Power Management ICs (PMIC) specifically for battery management. The series typically includes variants like the LV5117V-TLM-H, differing primarily in package style while maintaining core functional characteristics for single-cell charging.

Replacement Considerations

Direct substitutes may include other LV5117 series variants such as LV5117V-TLM-H, depending on package compatibility. Verify pinout and electrical parameters before substitution. No alternative part numbers are explicitly confirmed in public documentation for direct cross-referencing beyond the series.
