BQ25100AYFPR

Battery Chargers Overview

The BQ25100AYFPR is a standalone single-cell linear battery charger IC designed for Lithium-ion and Lithium Polymer batteries. It provides a regulated charge voltage of 4.284 V with a maximum output current of 250 mA. The device operates from a supply voltage up to 28 V and features a low quiescent current of 1 mA. It includes programmable pre-charge functionality and terminates charging when the current drops below 1 mA. The component is housed in a compact DSBGA-6 package, suitable for surface mount installation.

Battery Chargers Feature Summary

• Standalone linear charging architecture for single-cell Li-ion and Li-Polymer batteries
• Integrated thermal regulation to manage heat dissipation during charging cycles
• Programmable pre-charge stage for deeply discharged battery conditions
• Automatic recharge capability triggered by voltage drop below threshold

Battery Chargers Applications

• Portable consumer electronics requiring single-cell power management
• Wearable devices with limited board space constraints
• IoT sensors utilizing small form-factor lithium batteries
• Medical handheld devices needing reliable linear charging solutions

Battery Chargers Procurement Notes

Verify the specific suffix 'AYFPR' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering documentation matches the exact part number to avoid substitution errors. Cross-reference the package outline drawing with your PCB footprint design before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component for applications requiring a simple, cost-effective linear charging solution without external MOSFETs or inductors. It is appropriate for systems where input voltage exceeds battery voltage significantly but efficiency is secondary to simplicity. Consider the 250 mA current limit when sizing for larger battery capacities or faster charge time requirements.

Battery Chargers Part Context

This part belongs to the BQ2510x family of single-cell battery chargers from Texas Instruments. It shares architectural similarities with other members like the BQ25100BYFPR but differs in specific electrical parameters such as charge voltage tolerance and termination thresholds. The family is designed for minimal external component count.

Battery Chargers Replacement Considerations

The BQ25100BYFPR is a related variant within the same product family. Verify if the different charge voltage specification (4.2V vs 4.284V) meets your battery requirements. Check pin-to-pin compatibility and ensure the alternative package type matches your existing PCB layout constraints.
