Overview
The MP2678EG-104-LF-Z is a lithium-ion and lithium-polymer battery charger manufactured by Monolithic Power Systems. It operates within an input voltage range of 3.3 V to 10.4 V, delivering a regulated output current of 1.5 A. The device provides a precise output voltage between 4.6 V and 5.4 V. Designed for surface-mount installation, it utilizes a QFN-8 package. The component supports a maximum power dissipation of 1.25 W and functions reliably across an operating temperature range from -20 C to +85 C.
Feature Summary
- Supports charging for both lithium-ion and lithium-polymer battery chemistries
- Integrates thermal shutdown protection and current limiting capabilities
- Features low quiescent supply current for efficient power management
Applications
- Li-ion battery charger protection IC designs
- Portable electronic device power management systems
- Battery management applications requiring linear adjustment
Procurement Notes
Verify availability status carefully as the component is currently listed with restricted supply conditions. Confirm that the specific suffix matches the required pinout and electrical characteristics. Ensure compliance with RoHS standards before integration. Cross-reference the manufacturer datasheet for any recent revisions or obsolescence notices. Validate that the QFN-8 footprint aligns with the target PCB layout requirements.
Selection Notes
Select this component when designing circuits for single-cell Li-ion or Li-Po batteries requiring up to 1.5 A charge current. The wide input voltage range accommodates various power sources including USB and wall adapters. Consider the QFN-8 package size for space-constrained layouts. Evaluate the thermal performance given the 1.25 W dissipation limit in the intended application environment.
Part Context
This part belongs to the MP2678 series of battery management integrated circuits from Monolithic Power Systems. It is categorized under PMIC - Power Management ICs specifically for charge management. The device serves as a dedicated solution for managing energy storage in portable electronics, distinct from general-purpose switching regulators or other PMIC families.
Replacement Considerations
Check for compatible variants such as MP2678EG-104-LF-P if lead-free packaging differences are critical. Verify functional equivalence with other MPS battery chargers in the same series before substitution.
