Overview
The MP2619EV-LF-P is a monolithic lithium-ion battery charger IC from Monolithic Power Systems, designed for 2 to 3-cell battery packs. It supports a maximum charging current of 2A and operates with a battery pack voltage up to 12.6V. The device accepts an input supply voltage ranging up to 24V. It utilizes a 28-VFQFN package with exposed pad, measuring 4x5 mm. The component functions as a switching charger with programmable constant-current and constant-voltage profiles.
Feature Summary
- Supports charging for 2 to 3 series-connected lithium-ion battery cells
- Integrates power path management for system load prioritization
- Includes thermal regulation and charge termination timer features
Applications
- Portable electronic devices requiring multi-cell battery charging
- Industrial equipment utilizing 2S or 3S lithium-ion battery packs
- Consumer electronics with high-capacity battery requirements
Procurement Notes
Verify the suffix 'P' indicates tape-and-reel packaging rather than tube. Confirm RoHS compliance status matches the 'LF' designation. Ensure the specific revision level aligns with design requirements. Cross-reference the manufacturer part number against official distribution channels to avoid counterfeit components. Validate that the 28-QFN footprint matches the PCB layout specifications.
Selection Notes
Select this component when designing systems with 2 to 3 series lithium-ion batteries requiring up to 2A charging current. It is suitable for applications needing integrated power path management and operation from inputs up to 24V. Consider the 28-QFN package size for space-constrained designs. Verify thermal performance requirements given the exposed pad package type.
Part Context
This part belongs to the MP2619 family of battery chargers by Monolithic Power Systems. The EV suffix typically denotes an evaluation board variant, but the LF-Z/P suffixes indicate commercial packaged ICs. The MP2619 series focuses on multi-cell applications, distinguishing it from single-cell counterparts in the MPS portfolio. It integrates switching regulator functionality for efficient charging.
Replacement Considerations
MP2619EV-LF-Z is a direct equivalent in terms of function and pinout, differing primarily in packaging format (tube vs. reel). Verify compatibility if transitioning between packaging types.
