MM3220H16NRH

Overview

The MM3220H16NRH is a fixed positive single output LDO regulator manufactured by Mitsumi Electric Company Ltd. It belongs to the MM3220 series and is classified under power/management circuits. The device is designed for battery protection applications involving lithium-ion or lithium-polymer chemistries, supporting two cells. It features fault protections including over-current, over-voltage, and short-circuit safeguards. The component operates within a temperature range of -40°C to 85°C and is available in an SOT-26A package.

Feature Summary

• Provides battery protection for two-cell lithium-ion or lithium-polymer configurations
• Integrates over-current, over-voltage, and short-circuit fault protection mechanisms
• Operates reliably across an extended industrial temperature range from -40°C to 85°C

Applications

• Lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable electronic device power regulation

Procurement Notes

Verify the specific datasheet version and ordering suffixes with the manufacturer or authorized distributors. Confirm that the SOT-26A package matches your PCB footprint requirements. Ensure the operating voltage and current ratings align with your system design before procurement. Check for any RoHS or REACH compliance documentation if required for your region.

Selection Notes

Select this component when designing protection circuits for dual-cell lithium-based battery packs. Consider the SOT-26A package size constraints and the -40°C to 85°C operating temperature range. Evaluate the integrated fault protection features against your system's safety requirements. Compare performance characteristics with other members of the MM3220 series if alternative pinouts or functions are needed.

Part Context

The MM3220H16NRH is part of the broader MM3220 family produced by Mitsumi Electric Company Ltd. This series focuses on battery protection ICs for portable electronics. Similar parts in the lineup include the MM3220AA1NRH and MM3220C03NRH, which share similar packaging and application domains but may differ in specific electrical parameters or cell support configurations.

Replacement Considerations

Direct substitutes within the same family include MM3220AA1NRH and MM3220C03NRH. Verify pin compatibility and electrical specifications before substitution. Other manufacturers' equivalents require careful review of fault protection thresholds and operating temperature ranges.
