BQ24261MRGER

Battery Chargers Overview

The BQ24261MRGER is a host-controlled, single-input, single-cell switchmode Li-Ion battery charger manufactured by Texas Instruments. It supports a maximum input voltage of 30V and delivers up to 3A of charging current. The device integrates power-path management and USB On-The-Go (OTG) support for portable applications. It utilizes an I2C interface for configuration and monitoring. The component is housed in a 24-pin VQFN package with dimensions of 4mm x 4mm. It operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates power-path management to optimize system power distribution between the input source and the battery load.
• Supports USB On-The-Go (OTG) functionality to enable the device to act as a USB host for peripheral devices.
• Features a fully programmable I2C interface allowing comprehensive control over charging parameters and system states.

Battery Chargers Applications

• Portable consumer electronics requiring integrated battery charging and power path management
• USB-powered devices needing OTG host capability
• Single-cell lithium-ion battery powered systems

Battery Chargers Procurement Notes

Verify the specific suffix 'MRGER' against the official Texas Instruments datasheet to confirm the package type, tape-and-reel quantity, and temperature grade. Ensure compatibility with the required I2C address and pinout configuration for your PCB layout. Cross-reference the RoHS and REACH compliance status with the manufacturer's latest product information page.

Battery Chargers Selection Notes

Select this component when a single-cell Li-Ion solution requires both high-current switching regulation and USB OTG host capabilities. It is suitable for designs where space is constrained due to its compact VQFN footprint. Consider the 30V input tolerance if interfacing with non-standard or industrial power sources. Verify that the host microcontroller can manage the I2C communication protocol required for initialization.

Battery Chargers Part Context

This part belongs to the BQ2426x family of battery chargers from Texas Instruments. The family is characterized by host-controlled operation, distinguishing it from autonomous chargers. Variants within the series may differ in package options or thermal performance, but share the core architecture for single-cell charging and power path management.

Battery Chargers Replacement Considerations

Direct substitutes include other parts from the BQ2426x family such as the BQ24261RGER or BQ24261YFFR, provided the package and reel specifications match the design requirements. Verify pin-to-pin compatibility before substitution.
