BQ25100YFPR

Battery Chargers Overview

The BQ25100YFPR is a standalone linear battery charger from Texas Instruments designed for single-cell lithium-ion and lithium-polymer batteries. It features an integrated power path management system that automatically sources power from the input supply to the system load while simultaneously charging the battery. The device supports USB input voltages up to 6.45 V and provides a programmable charge current of up to 250 mA. Key electrical parameters include a fixed output voltage of 4.284 V, a maximum operating junction temperature of +125°C, and a minimum operating temperature of -5°C. It is housed in a compact 6-DSBGA package.

Battery Chargers Feature Summary

• Integrates power path management to prioritize system power while charging the battery
• Supports automatic recharge functionality triggered by battery voltage drop below threshold
• Includes thermal regulation to reduce charge current based on die temperature
• Provides comprehensive safety protections against overvoltage, overtemperature, and short circuits

Battery Chargers Applications

• Portable consumer electronics powered by single-cell lithium batteries
• USB-powered devices requiring integrated battery charging and system power distribution
• Wearable technology with space-constrained PCB layouts
• IoT sensors and modules utilizing small form-factor energy storage

Battery Chargers Procurement Notes

Verify the specific suffix YFPR corresponds to the DSBGA-6 package and cut tape or reel packaging options as listed by authorized distributors. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and thermal pad configuration specified in the official datasheet to prevent compatibility issues during integration.

Battery Chargers Selection Notes

Select this component when designing systems that require simultaneous system power delivery and battery charging from a single source without external switches. It is suitable for applications where board space is limited due to its small footprint. Consider the 250 mA current limit and 4.284 V output voltage to ensure compatibility with the target battery chemistry and system load requirements before finalizing the design.

Battery Chargers Part Context

This part belongs to the BQ25100 family of linear chargers from Texas Instruments. The family includes variants such as BQ25100BYFPT and BQ25100AYFPR, which share similar core functionalities but may differ in package types or specific manufacturing revisions. These devices are categorized under Power Management ICs (PMIC) specifically for battery charge management within portable electronic designs.

Battery Chargers Replacement Considerations

Direct substitutes within the same series include BQ25100BYFPT and BQ25100AYFPR. Verify package compatibility and pin alignment before substitution. Cross-family replacements require careful evaluation of current limits and interface differences.
