Overview
The MP2605DQ-LF-Z is a linear charge management IC designed for single-cell lithium-ion and lithium-polymer batteries. It supports an input voltage range of 3.5 V to 6.5 V and delivers a regulated output voltage of 4.2 V with a maximum output current of 1 A. The device operates within a temperature range of -40°C to +85°C and features a quiescent supply current of 500 uA. It is housed in a QFN-10 package suitable for surface mount installation.
Feature Summary
- Linear charging architecture optimized for single-cell lithium-based battery chemistries
- Integrated trickle charge capability for deeply discharged battery conditions
- Supports standard constant-current and constant-voltage charging profiles
Applications
- Single-cell lithium-ion battery charging systems
- Lithium-polymer battery power management modules
- Portable electronic devices requiring compact linear charging solutions
Procurement Notes
Verify the specific suffix and tape/reel configuration against official Monolithic Power Systems documentation prior to ordering. Confirm that the QFN-10 footprint matches the target PCB layout. Ensure compliance with RoHS requirements as specified in the manufacturer's environmental declarations.
Selection Notes
Select this component when designing circuits for single-cell lithium batteries requiring a simple linear charging topology. The 3.5 V to 6.5 V input range accommodates standard USB and adapter sources. Consider thermal dissipation capabilities given the linear regulation method at higher input-to-output voltage differentials.
Part Context
This part belongs to the MP2605 series of battery management products from Monolithic Power Systems. It serves as a dedicated solution for managing charge cycles in portable applications, distinct from switching charger alternatives or multi-cell configurations found in other product lines.
Replacement Considerations
MP2602DQ-LF-Z: Similar 1A linear charger but limited to a 5.5 V maximum input voltage. MP2604DQ-LF-Z: Comparable 1A linear charger with a wider 6.5 V input voltage tolerance.
