MP2632GR-Z

Overview

The MP2632GR-Z is a fully integrated switching battery charger from Monolithic Power Systems, designed for single-cell lithium-ion or lithium-polymer batteries. It features a 3A programmable charging current and supports selectable charge voltages of 4.2V, 4.35V, and 4.45V with 0.5% accuracy. The device operates within an input voltage range of 4.65V to 6V, tolerating up to 14V. It integrates power path management with an IN-to-SYS direct path, providing up to 3.0A boost output current. The component utilizes a QFN-26 (4x4) package.

Feature Summary

• Integrates system power path management with priority given to the IN-to-SYS direct path over the charging circuit.
• Supports three-stage charging profiles including trickle, constant current, and constant voltage modes with automatic recharge capability.
• Includes four LED drivers for battery status indication and independent torch-on control functionality.
• Features comprehensive protection mechanisms such as thermal regulation, short-circuit protection, and NTC temperature monitoring.

Applications

• Power bank designs requiring efficient power path management
• Portable consumer electronics powered by single-cell lithium batteries
• Handheld devices utilizing flashlight functions controlled via the IC

Procurement Notes

Verify the specific ordering suffix against official Monolithic Power Systems documentation to confirm package type and environmental compliance. Ensure that any suffix variations do not alter the functional parameters unless explicitly stated in the datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring high-current charging capabilities alongside simultaneous system power delivery. The integrated power path simplifies design by eliminating external power path controllers. Consider the available charge voltage options to match the specific chemistry requirements of the target lithium-ion or lithium-polymer battery cell being utilized in the application.

Part Context

This part belongs to the MP2632 series of battery chargers manufactured by Monolithic Power Systems. It is categorized under PMIC - Battery Management within the power management integrated circuit family. The GR-Z suffix typically denotes a lead-free, halogen-free RoHS-compliant variant packaged in a QFN-26 format suitable for surface-mount assembly.
