BQ25123YFPT

Battery Chargers Overview

The BQ25123YFPT is a highly integrated battery charge management solution designed for wearable applications. It features a low quiescent current of 700 nA and operates within a temperature range of -40°C to +85°C. The device utilizes a DSBGA (YFP) package with 25 pins, measuring 2.53x2.47 mm. It supports lithium-ion and lithium-polymer battery types.

Battery Chargers Feature Summary

• Highly integrated charge management architecture
• Ultra-low quiescent current consumption
• Compact footprint suitable for space-constrained designs

Battery Chargers Applications

• Wearable electronic devices
• Lithium-ion battery charging systems
• Lithium-polymer battery charging systems

Battery Chargers Procurement Notes

Verify the specific suffix YFPT corresponds to the cut tape or reel packaging variant required for your assembly process. Confirm that the operating temperature range meets your environmental specifications. Ensure compatibility with the target lithium-ion or lithium-polymer cell chemistry before integration into the final product design.

Battery Chargers Selection Notes

Select this component when ultra-low standby current is critical for extending battery life in portable devices. The compact DSBGA package makes it suitable for applications with strict size constraints. Consider the 700 nA quiescent current as a key differentiator for wearables compared to standard linear chargers.
