BQ25101HYFPR

Battery Chargers Overview

The BQ25101HYFPR is a single-cell linear battery charger manufactured by Texas Instruments, designed for lithium-ion and lithium polymer batteries. It features a 250 mA output current capability with a precise 4.35 V output voltage regulation. The device operates on a supply voltage range of 4.45 V to 6.5 V. Key electrical specifications include a 1 mA charge termination threshold and an ultra-low 75 nA battery leakage current, optimizing standby power consumption. The component is housed in a compact DSBGA-6 surface-mount package.

Battery Chargers Feature Summary

• Ultra-low battery leakage current minimizes parasitic drain during storage or standby modes.
• Integrated thermal regulation automatically adjusts charging current to maintain safe junction temperatures.
• Programmable charge termination ensures accurate full-battery detection via the 1 mA cutoff threshold.

Battery Chargers Applications

• Portable consumer electronics requiring single-cell lithium-ion power sources
• Wearable devices with strict space and power efficiency constraints
• IoT sensors utilizing lithium-polymer battery configurations

Battery Chargers Procurement Notes

Verify the specific suffix (HYFPR) against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with RoHS standards and check for any recent product change notices that may affect pinout or material composition prior to final procurement authorization.

Battery Chargers Selection Notes

Select this component when designing circuits for single-cell lithium chemistry where low quiescent current is critical. The 250 mA limit suits small-capacity cells, while the wide input voltage range accommodates various USB power sources. Confirm that the DSBGA-6 footprint aligns with available PCB layout resources and thermal dissipation requirements.

Battery Chargers Part Context

This part belongs to the BQ25101H series of linear chargers from Texas Instruments. It is distinct from other family members like the BQ25100B, which offers different voltage outputs and termination thresholds. The H-series designation typically indicates specific optimization for high-efficiency operation within the single-cell management category.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Verify cross-compatibility with similar Texas Instruments models such as the BQ25100 series only if datasheet parameters match exactly.
