Overview
The MP2608DQ-LF-Z is a linear battery charger IC designed for single-cell lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 3.5 V to 5.5 V and provides a regulated output voltage of 4.2 V with a maximum charge current of 1 A. The device features a low quiescent current of 80 uA and supports timer-based charging termination. It is housed in a QFN-10 package suitable for surface mount installation, operating reliably between -40 C and +85 C.
Feature Summary
- Integrates a programmable timer function to terminate the charge cycle automatically if the battery fails to reach full charge within the specified duration.
Applications
- Charging single-cell lithium-ion batteries
- Charging single-cell lithium-polymer batteries
Procurement Notes
Verify component authenticity through authorized distribution channels due to limited supply status. Confirm RoHS compliance documentation matches the specific manufacturing batch. Ensure the QFN-10 footprint aligns with PCB design requirements before finalizing procurement orders.
Selection Notes
Select this component when a simple linear solution is required for 1 A charging applications. It is appropriate for designs where input voltage remains close to the battery voltage. Consider thermal dissipation capabilities as the device handles power loss internally during the charging process.
Part Context
This part belongs to the MP2608 series from Monolithic Power Systems. It serves as a dedicated charge management solution within the PMIC category. The device integrates necessary protection and control logic for safe single-cell battery charging operations.
Replacement Considerations
MP2602DQ-LF-Z: Similar linear charger but lacks the integrated timer feature found in the MP2608.
FAQ
What is the purpose of the timer function?
The timer terminates the charge cycle if the battery does not reach full charge within the programmed time, preventing indefinite trickle charging.
Which battery chemistries are supported?
The device supports both Lithium-ion and Lithium Polymer single-cell batteries.
