Battery Chargers datasheet and documents for BQ25100BYFPT

BQ25100BYFPT

Battery Chargers Overview

The BQ25100BYFPT is a standalone linear battery charger IC designed for single-cell lithium-ion and lithium-polymer batteries. It features a maximum charge current of 250 mA and an output voltage of 4.284 V. The device operates with a supply voltage range from 4.45 V to 6.45 V. It utilizes a DSBGA-6 package and supports surface mount installation. The component includes JEITA battery temperature monitoring via a thermistor pin, overvoltage protection, thermal regulation, and under-voltage lockout. Termination current is set at 1 mA, with a battery leakage current of 75 nA.

Battery Chargers Feature Summary

Standalone RC-settable control topology requiring no microcontroller
Integrated JEITA temperature monitoring using external thermistor
Comprehensive protection including thermal regulation and short-circuit prevention

Battery Chargers Applications

Single-cell Li-Ion battery-powered portable devices
Li-Polymer battery charging in compact consumer electronics
USB-powered peripheral battery management systems

Battery Chargers Procurement Notes

Verify the specific suffix BYFPT against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the intended PCB footprint for the DSBGA-6 package. Confirm that the application circuit meets the required input voltage range of 4.45 V to 6.45 V for proper operation.

Battery Chargers Selection Notes

Select this component for applications requiring a minimal external component count and low quiescent current. It is suitable for space-constrained designs due to the small DSBGA-6 package. Consider the 250 mA charge limit when sizing for larger capacity batteries or faster charge time requirements.

Battery Chargers Part Context

This part belongs to the BQ25100B series of linear battery chargers from Texas Instruments. It is specifically engineered for simple, cost-effective charging solutions where interface complexity must be minimized. The series supports standard lithium chemistries with integrated safety features.
