MM3575A02WBH

Overview

The MM3575A02WBH is a multi-cell battery protection IC designed for lithium-ion and lithium-polymer battery packs. It supports configurations of three to five cells in series, providing comprehensive overcharge, overdischarge, and overcurrent protection. The device integrates high-side P-channel MOSFETs for efficient control within the package. It operates with a wide supply voltage range suitable for various battery chemistries. The component utilizes a VSOP-24 package with a 5.6mm width, facilitating compact PCB layouts for portable electronic devices requiring reliable power management.

Feature Summary

• Integrated protection against overcharge, overdischarge, and short-circuit conditions for multi-cell battery stacks
• Built-in high-side P-channel MOSFETs eliminate the need for external switching components
• Supports flexible cell configurations ranging from three to five series-connected cells

Applications

• Lithium-ion battery pack protection in portable consumer electronics
• Power management systems for cordless tools and appliances
• Battery safety circuits in medical equipment and industrial devices

Procurement Notes

Verify the specific suffix WBH corresponds to the required tape and reel packaging quantity when ordering. Confirm that the VSOP-24 package dimensions align with the target PCB footprint design. Ensure compatibility with the intended battery cell chemistry and maximum operating voltage requirements before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring integrated protection for three to five series cells without external FETs. Consider the VSOP-24 package size constraints during layout planning. Evaluate thermal performance requirements as the internal MOSFETs handle load currents directly. Verify that the protection thresholds meet the specific safety standards of the end product.
