BQ24253RGER

Battery Chargers Overview

The BQ24253RGER is a single-cell lithium-ion battery charger from Texas Instruments, housed in a VQFN-24 surface-mount package. It delivers a fixed 4.2V output voltage with a maximum charge current of 2A. The device operates on input supply voltages up to 18V and supports I2C/SW mode interfaces for configuration. It is designed for applications requiring efficient power management within a compact form factor.

Battery Chargers Feature Summary

• Supports I2C or Single Wire interface modes for system control
• Integrates power path management for simultaneous system load handling
• Includes programmable charge termination and thermal regulation features

Battery Chargers Applications

• Portable consumer electronics charging
• Battery-powered handheld devices
• IoT sensor node power management

Battery Chargers Procurement Notes

Verify the specific suffix RGER against the official datasheet to confirm the reel packaging type and tape width specifications. Ensure the component matches the required VQFN-24 footprint dimensions and pinout configuration for your PCB layout. Cross-reference the RoHS compliance status and operating temperature range with your environmental design constraints before finalizing the procurement order.

Battery Chargers Selection Notes

Select this model when a fixed 4.2V output is sufficient for the target lithium-ion cell chemistry. The 2A current rating suits moderate capacity batteries where rapid charging is not the primary constraint. Consider the VQFN-24 package if board space is limited but thermal dissipation needs are manageable without the larger DSBGA options available in the series.

Battery Chargers Part Context

This component belongs to the bq2425x family of single-cell switch-mode chargers. It shares architectural similarities with models like the BQ24250 and BQ24259 but differs in output voltage configuration and interface capabilities. The RGER variant specifically denotes the reel-packaged version of the standard chip, intended for automated surface-mount assembly processes.

Battery Chargers Replacement Considerations

The BQ24253YFFR serves as a parameter-equivalent alternative within the same family, offering identical electrical performance but utilizing a DSBGA-30 package instead of VQFN-24. Verify that the change in physical footprint does not impact the existing PCB design before substituting.
