MP2660GC-0000-Z

Overview

The MP2660GC-0000-Z is a high-integration single-cell lithium-ion or lithium-polymer battery charger IC from Monolithic Power Systems. It features an integrated system power path management function, allowing simultaneous system load powering and battery charging via AC adapter or USB interfaces. The device supports trickle, constant current (CC), and constant voltage (CV) charging profiles with automatic recharge capabilities. Key electrical parameters include a maximum input source voltage of 13V, a charging voltage accuracy of ±0.5%, and a 100mΩ switch for battery-to-system power delivery. It operates within a temperature range of -40°C to +125°C and utilizes a compact 9-pin WLCSP package measuring 1.55mm x 1.55mm.

Feature Summary

• Integrated power path management automatically selects input, battery, or both to ensure continuous system power supply while charging.
• I2C control interface allows programmable settings for input current limits, charging current, battery regulation voltage, and safety timers.
• Built-in protection mechanisms include short-circuit protection, battery over-discharge prevention via UVLO, and thermal regulation.
• Full power switch integration eliminates the need for external blocking diodes, reducing component count and board space.

Applications

• Small form factor portable electronic devices requiring efficient single-cell battery charging
• USB-powered consumer electronics with integrated power path requirements
• IoT devices and wearables utilizing lithium-ion or lithium-polymer batteries

Procurement Notes

Verify the specific suffix (P or Z) against the required tape-and-reel packaging configuration before ordering. Confirm that the I2C address and programming parameters align with the target system design. Ensure the evaluation kit EVKT-MP2660 is available if hardware validation is required during the development phase. Cross-reference the latest datasheet for any updates to pinout or electrical characteristics.

Selection Notes

Select this component for designs prioritizing minimal footprint due to its WLCSP-9 package size. It is suitable for applications where independent management of charging current and system load current is necessary to maintain battery health. Consider the 13V maximum input rating when designing for non-standard USB or AC adapter sources. The I2C interface is essential if dynamic adjustment of charging parameters is required by the host microcontroller.
