BQ25100AYFPT

Battery Chargers Overview

The BQ25100AYFPT is a standalone linear battery charger designed for single-cell lithium-ion and lithium-polymer batteries. It features an integrated power path management system that automatically optimizes system power requirements, prioritizing the supply to the system load over battery charging when input current is limited. The device supports USB host or wall adapter inputs with a maximum operating voltage of 6.45 V. It provides a programmable charge current up to 250 mA and regulates the cell voltage to 4.284 V. The component operates within a junction temperature range of -5°C to +125°C and is housed in a compact 6-DSBGA package.

Battery Chargers Feature Summary

• Integrates power path management to balance system load and battery charging without external components
• Supports automatic input current limiting for USB host or wall adapter sources
• Includes comprehensive safety features such as thermal regulation and charge termination

Battery Chargers Applications
