BQ24270RGER

Battery Chargers Overview

The BQ24270RGER is a single-cell lithium-ion battery charger IC from Texas Instruments, designed for portable applications. It operates within an input voltage range of 3.5 V to 6.5 V and delivers a programmable charge current up to 1.5 A. The device features an adjustable output voltage and utilizes an I2C interface for configuration. Packaged in a 24-VQFN (4x4 mm) format with exposed pad, it supports surface-mount installation. The component functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates dual-input path management for automatic source selection between adapter and USB host.
• Provides programmable constant-current and constant-voltage charging profiles tailored for single-cell lithium-ion batteries.
• Includes comprehensive safety mechanisms such as thermal regulation, overvoltage protection, and short-circuit detection.

Battery Chargers Applications

• Portable consumer electronics requiring compact power management solutions
• Single-cell lithium-ion battery powered devices
• USB-powered gadgetry with integrated charging capabilities

Battery Chargers Procurement Notes

Verify the specific suffix 'RGER' corresponds to the tape-and-reel packaging variant when sourcing. Confirm that the required I2C address and programming parameters align with your system design before procurement. Ensure compatibility with the 24-VQFN footprint during PCB layout validation.

Battery Chargers Selection Notes

Select this model for designs requiring a balance between high charge current and small form factor. It is suitable for systems where input power sources may vary between wall adapters and USB ports. Consider the I2C interface requirements for dynamic control versus fixed-configuration alternatives.

Battery Chargers Part Context

This component belongs to the BQ24270 family of battery chargers. It shares functional similarities with the BQ24271 but differs in specific pinout or feature configurations. The RGER designation indicates the reel packaging option, distinct from cut-tape variants like RGET.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with BQ24271 series components only if datasheet specifications match exactly.
