Overview
The MP2617AGL-Z is a monolithic switching battery charger designed for single-cell lithium-ion batteries with a maximum charge voltage of 4.35V. It operates within an input supply voltage range of 4V to 10V and supports up to 3A charging current. The device integrates synchronous buck regulation, NVDC power path management, and full power switches in a QFN-20 package. It features adjustable input current limits compatible with USB 2.0/3.0 specifications and includes thermal foldback control.
Feature Summary
- Integrates intelligent NVDC power path management to prioritize system load while charging the battery independently.
- Supports simultaneous operation from USB and high-power DC adapters with programmable input current limiting.
- Includes comprehensive protection mechanisms such as thermal foldback, battery temperature monitoring, and over-temperature fault protection.
Applications
- Single-cell lithium-ion battery charging in tablet computers
- Portable electronic devices requiring integrated power path management
- USB-powered consumer electronics
Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's latest datasheet to confirm packaging configuration and RoHS compliance status. Ensure the component variant matches the required 4.35V output specification for your target battery chemistry. Cross-reference the QFN-20 footprint dimensions with your PCB layout guidelines prior to procurement.
Selection Notes
Select this component when a 4.35V charge voltage is required for high-voltage lithium cells. It is suitable for designs needing integrated power path management to support system loads during charging. Consider the 4V to 10V input range compatibility with available power sources. Verify that the 3A current capability meets the application's performance requirements.
Part Context
This part belongs to the MP2617 family of single-cell switching chargers from Monolithic Power Systems. It shares architectural similarities with the MP2617BGL-Z but differs in the maximum charge voltage setting (4.35V versus 4.2V). The series is characterized by high integration levels and efficient synchronous buck topology.
Replacement Considerations
MP2617AGL-P is a direct pin-compatible alternative with different packaging. MP2617BGL-Z is functionally similar but configured for 4.2V lithium-ion batteries.
