BQ25101HYFPT

Battery Chargers Overview

The BQ25101HYFPT is a standalone single-cell lithium-ion or lithium polymer battery charger manufactured by Texas Instruments. It operates within a supply voltage range of 4.45 V to 6.5 V and delivers a maximum output current of 250 mA. The device features a fixed charge termination voltage of 4.35 V. It incorporates a 1 mA termination threshold and achieves a battery leakage current as low as 75 nA in the standby state. The component is housed in a compact 6-DSBGA package with dimensions of 1 mm length and 0.5 mm maximum height, suitable for surface mount installation.

Battery Chargers Feature Summary

• Standalone linear charging architecture requiring minimal external components
• Ultra-low battery leakage current capability for extended standby retention
• Integrated thermal regulation to manage junction temperature during operation

Battery Chargers Applications

• Portable consumer electronics powered by single-cell lithium batteries
• Wearable devices requiring minimal footprint power management
• IoT sensors and modules with strict standby current constraints

Battery Chargers Procurement Notes

Verify the specific suffix HYFP against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB layout for the DSBGA-6 package. Confirm RoHS compliance status through the manufacturer's latest release notes before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when designing circuits for single-cell Li-Ion or Li-Po batteries requiring a simple, cost-effective charging solution. It is appropriate for applications where space is limited and ultra-low quiescent current is critical for battery life. Compare against the BQ25100 series if different termination voltages or input voltage ranges are required.

Battery Chargers Part Context

This part belongs to the BQ25101H family of battery chargers from Texas Instruments. It is designed specifically for portable applications needing efficient single-cell charging. The device integrates necessary protection features while maintaining a small physical profile, distinguishing it from larger multi-cell or high-current charger solutions in the broader PMIC portfolio.

Battery Chargers Replacement Considerations

The BQ25101HYFPR serves as an alternative reel packaging option for the same functional device. Verify that any substitute maintains the identical 6-DSBGA footprint and electrical specifications to ensure direct board compatibility without schematic modifications.
