MP2661GC-XXXX-Z

Battery Chargers Overview

The MP2661GC-XXXX-Z is a single-cell lithium-ion battery charger IC from Monolithic Power Systems. It supports a 4.65V system voltage and provides up to 500mA of charging current. The device features an I2C-controlled interface for programmable parameters. It integrates power path management to supply the system load while charging the battery. The component operates within a supply voltage range of 4.35V to 5.5V and functions in temperatures from -40°C to +125°C. It utilizes a 9-pin WLCSP package measuring 1.55mm x 1.55mm.

Battery Chargers Feature Summary

• Integrates complete power path management for simultaneous system powering and battery charging
• Features an I2C control interface for programmable charging parameters and status reporting
• Includes built-in protection mechanisms such as thermal regulation and short-circuit protection

Battery Chargers Applications

• Single-cell Li-Ion battery charging in portable devices
• USB-powered consumer electronics with integrated power path requirements
• Small form factor mobile applications requiring compact packaging

Battery Chargers Procurement Notes

Verify the specific suffix code (e.g., P or Z) against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Confirm RoHS compliance status directly with the supplier documentation. Ensure the ordering part number matches the required pinout and functional variant, as suffixes may indicate differences in tape-and-reel quantities or material composition rather than performance changes.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell lithium batteries is required with precise I2C configurability. The integrated power path simplifies design by eliminating external switching components for system load sharing. Consider the 9-WLCSP footprint constraints during PCB layout. Verify that the application input voltage remains within the specified 4.35V to 5.5V operational range for reliable performance.

Battery Chargers Part Context

This part belongs to the MP266x series of linear battery chargers designed for portable electronics. It shares architectural similarities with the MP2660 but is optimized for 4.65V system architectures. The series emphasizes high integration and minimal external component count. It serves as a specialized power management solution for applications where space efficiency and programmable charging profiles are critical design factors.
