Overview
The MP2615CGQ-Z is a high-efficiency switching battery charger from Monolithic Power Systems, designed for single or dual-cell lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 4.75 V to 18 V and delivers a maximum programmable charging current of 2.1 A. The device features a fixed output voltage of 4.5 V and utilizes a QFN-16 (3mm x 3mm) package. It supports a wide operating temperature range from -40°C to +85°C with a quiescent supply current of 1.1 mA.
Feature Summary
- Integrates power MOSFETs and implements constant on-time control for up to 99% duty cycle operation.
- Provides precise charge management with independent loops for constant current and constant voltage regulation.
- Includes comprehensive protection mechanisms such as over-temperature, cycle-by-cycle over-current, and reverse discharge lockout.
Applications
- Portable electronic devices requiring efficient single-cell lithium-ion battery charging
- Dual-cell lithium-ion battery pack management systems
- Lithium-polymer battery charging in compact consumer electronics
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the QFN-16 package dimensions match your PCB footprint requirements. Ensure the input voltage source remains within the 4.75 V to 18 V operational window to maintain proper functionality and thermal performance during continuous charging cycles.
Selection Notes
Select this component when designing for single or dual-cell Li-ion/Li-Po applications requiring integrated power switches. The 2.1 A output capability suits medium-power portable devices. Consider the 3mm x 3mm QFN-16 package for space-constrained layouts. Verify that the external sense resistor selection aligns with the desired 2.1 A maximum current limit and thermal dissipation constraints.
Part Context
This part belongs to the MP2615C series of battery chargers. It shares core architecture with variants like MP2615GQ-Z and MP2615GQ-P, differing primarily in packaging quantities and specific manufacturing lot attributes. The CGQ-Z designation specifies the commercial grade temperature range and reel/cut-tape packaging configuration available through distributors.
Replacement Considerations
MP2615GQ-P serves as a direct functional substitute within the same series, offering identical electrical characteristics but potentially different packaging quantities.
