The device operates at an operating supply voltage of 3.3 V and draws an operating supply current of 7.5 mA. It features a power dissipation rating of 500 mW and is housed in a 32-TQFN (4x4) package. The component is classified as moisture sensitive.

Battery Management Feature Summary

• Provides comprehensive status information for lithium-ion battery packs
• Functions as a drop-in solution for battery pack monitoring
• Supports battery configurations ranging from 2 to 16 stacked cells

Battery Management Applications

• Lithium-ion battery pack fuel gauging
• Battery management systems for stacked cell configurations
• Portable electronic devices requiring battery status monitoring

Battery Management Procurement Notes

Verify the specific suffix code (e.g., -P, -Z) against the manufacturer's current product status, as variants may be obsolete or discontinued. Confirm the exact package marking and date code requirements for your assembly process. Ensure compliance with RoHS directives if specified in the final datasheet. Check for moisture sensitivity level (MSL) handling requirements during storage and reflow soldering to prevent package damage.

Battery Management Selection Notes

Select this component when a dedicated fuel gauge IC is required for lithium-ion batteries with up to 16 series cells. The 3.3 V supply requirement must align with the system logic levels. Consider the 32-TQFN package size for PCB layout constraints. Verify that the 7.5 mA supply current fits within the system's power budget. This part is suitable for applications needing accurate state-of-charge reporting without external microcontroller intervention for basic fuel gauging.

Battery Management Part Context

This component belongs to the Monolithic Power Systems MPF42792 family of battery management ICs. It is specifically engineered for high-cell-count lithium-ion applications. The device integrates necessary sensing and communication interfaces to replace discrete solutions. It serves as a direct replacement for older fuel gauge designs in portable electronics and industrial equipment requiring reliable battery monitoring.

Battery Management Replacement Considerations

Check for direct pin-to-pin replacements within the MPS portfolio. Verify compatibility with existing firmware if digital interfaces are used. Ensure thermal performance matches the original design intent given the 500 mW dissipation limit.
