MM3575D01WBH

Overview

The MM3575D01WBH is a multi-cell battery protection integrated circuit manufactured by Mitsumi Electric Company Ltd. It is designed for lithium-ion and lithium-polymer battery packs consisting of three to five cells in series. The device provides comprehensive protection functions including overcharge, overdischarge, and short-circuit detection. It operates with an end-of-discharge voltage threshold of 2.8V per cell. The component is housed in a compact LSSOP-24 package with a 5.6mm width, suitable for space-constrained portable electronic applications requiring reliable battery management.

Feature Summary

• Integrated protection for 3 to 5 series-connected lithium-ion or lithium-polymer cells
• Monitors individual cell voltages to prevent overcharge and overdischarge conditions
• Detects short-circuit events to protect the battery pack from excessive current
• Utilizes a low-profile LSSOP-24 package for efficient PCB layout

Applications

• Portable consumer electronics such as laptops and tablets
• Power tool battery packs
• Medical equipment battery systems
• Uninterruptible power supply (UPS) modules

Procurement Notes

Verify the exact suffix D01 against the manufacturer's latest datasheet to confirm pinout and electrical specifications. Ensure the LSSOP-24-5.6mm package dimensions match your PCB footprint design. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the part number with official Mitsumi distributors to avoid counterfeit components.

Selection Notes

Select this IC when designing battery packs with 3 to 5 series cells requiring integrated protection. Consider the LSSOP-24 package size constraints during PCB layout. Evaluate the 2.8V discharge cutoff against your system's minimum operating voltage requirements. Ensure the thermal performance of the package meets the application's heat dissipation needs.

Part Context

This component belongs to the MM3575 series of battery management ICs from Mitsumi. The series includes variants like MM3575A02WBH, which share similar protection functionalities but may differ in specific thresholds or packaging. The MM3575D01WBH is specifically configured for multi-cell lithium-based chemistries, distinguishing it from single-cell protection devices.

Replacement Considerations

Direct substitutes include other MM3575 series variants such as MM3575A02WBH, provided the electrical parameters and package compatibility are verified. Check for equivalent protection thresholds and switching speeds before substitution.
