MP2602DQ-LF-P

Overview

The MP2602DQ-LF-P is a high-performance single-cell lithium-ion linear charger from Monolithic Power Systems. It integrates high-voltage input protection capable of withstanding up to 28V input surges, making it suitable for adapter or USB inputs. The device supports adjustable charging currents ranging from 85mA to 1A and features a proprietary constant voltage auto-recharge function. Key electrical parameters include a 4.2V output voltage, an operating supply voltage range of 3.5V to 5.5V, and a quiescent current of 90µA on VIN. It operates within a temperature range of -40°C to +85°C and is housed in a compact 10-pin QFN package measuring 3mm x 3mm.

Feature Summary

• Integrates high-voltage input protection to withstand up to 28V input surges
• Provides trickle charge capability alongside standard CC/CV charging modes
• Includes battery temperature monitoring and thermal regulation for safety
• Features reverse current blocking to prevent battery discharge when input is removed

Applications

• Portable electronic devices requiring single-cell Li-Ion battery charging
• USB-powered consumer electronics
• Adapter-powered mobile gadgets
• Battery management systems in compact handheld devices

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm package and tape/reel specifications. Ensure the ordering part number matches the required quantity format, such as cut tape versus full reel quantities. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when high-voltage surge tolerance is required for direct adapter connections. It is appropriate for designs needing integrated trickle charging and thermal protection without external components. Consider the small QFN footprint for space-constrained layouts. Verify that the 1A maximum current meets the target battery's charging requirements.

Part Context

This part belongs to the MP2602 series of single-cell linear chargers. It shares core functionalities with variants like the MP2602DQ-LF-Z but may differ in packaging or shipping configuration. The series is designed for applications demanding robust input protection and efficient charging profiles in a minimal form factor.

Replacement Considerations

MP2602DQ-LF-Z is a verified substitute within the same series. Check datasheets for pin compatibility and functional equivalence before substitution.
