MP2639CGR-P

Overview

The MP2639CGR-P is a battery charge management IC from Monolithic Power Systems, designed for single-cell Lithium-ion and Lithium Polymer batteries. It operates within a supply voltage range of 4.5 V to 6 V and delivers an output voltage between 2.5 V and 4.35 V. The device supports a maximum charging current of 2 A and features a low quiescent current of 2.5 mA. It is housed in a QFN-24 package suitable for surface mount installation and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrated switch-mode charger architecture for efficient power conversion
• Supports standard Lithium-ion and Lithium Polymer battery chemistries
• Operates with low quiescent current to minimize standby power consumption

Applications

• Single-cell portable electronic devices
• Consumer electronics requiring compact power management
• Battery-powered mobile equipment

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and functional compatibility. Datasheet specifications define electrical limits; ensure input voltage and thermal conditions align with design requirements before integration.

Selection Notes

Select this component for applications requiring a single-cell Li-ion or Li-Po solution with moderate charging currents. Compare package dimensions and thermal performance against alternative PMICs to ensure mechanical fit and adequate heat dissipation for the target enclosure.

Part Context

This part belongs to the MP2639 series of battery chargers. It shares architectural similarities with other MPS charge management ICs but is distinct in its single-cell configuration and specific operating voltage ranges compared to multi-cell variants.

Replacement Considerations

MP2639BGR-Z: Single-cell variant with different max current ratings. MP2639AGR-Z: Dual-cell variant for higher voltage stacks. Verify pin compatibility and control logic when substituting.
