MP2661GC-XXXX-P

Overview

The MP2661GC-XXXX-P is a single-cell lithium-ion battery charger IC from Monolithic Power Systems. It features a 500mA constant-current charge capability and an I2C-controlled interface for programmable parameters. The device integrates power path management to supply system loads while charging the battery. It operates with a maximum input voltage of 13V and supports a wide operating temperature range from -40°C to +125°C. The component is housed in a compact 9-WLCSP package measuring 1.55mm x 1.55mm.

Feature Summary

• Integrates full power path management for simultaneous system powering and battery charging
• Includes built-in protection mechanisms such as overcurrent, overtemperature, and short-circuit safeguards
• Features an I2C interface allowing programmable control of charging current, voltage, and timers

Applications

• Single-cell lithium-ion battery charging in portable electronics
• Power management systems requiring integrated power path switching
• Compact consumer devices utilizing WLCSP packaging constraints

Procurement Notes

Verify the specific suffix (e.g., P or Z) against official datasheets to confirm tape-and-reel specifications and environmental compliance status. Confirm that the XXXX placeholder matches the required binning or marking codes for your assembly process. Ensure compatibility with the 13V maximum input rating and I2C address configuration before finalizing procurement orders.

Selection Notes

Select this component when a linear charger topology with integrated power path management is required for single-cell applications. It is suitable for designs needing I2C configurability rather than fixed hardware settings. Consider the 9-WLCSP footprint for space-constrained layouts. Verify thermal performance requirements given the junction temperature limits and lack of external switching components.

Part Context

This part belongs to the MPS MP266x series of I2C-controlled battery chargers. It shares functional similarities with the MP2660 but is optimized for a 4.65V system architecture. The series targets small form-factor portable devices where integrated power path management reduces external component count.

Replacement Considerations

MP2661GC-0000-Z is listed as a parameter equivalent substitute.
