BQ24150AYFFR

Battery Chargers Overview

The BQ24150AYFFR is a fully integrated switch-mode lithium-ion and lithium-polymer battery charger manufactured by Texas Instruments. It operates within a supply voltage range of 4V to 6V and supports a maximum charge current of 1.25A. The device features an I2C interface for programmable control of charging parameters, including current, timer, and voltage settings. Designed for single-cell applications, it utilizes a 20-DSBGA package and functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Fully integrated synchronous switch-mode architecture with internal power FETs
• I2C programmable charging parameters for precise system control
• Integrated thermal regulation and fault protection mechanisms

Battery Chargers Applications

• Portable consumer electronics requiring compact power management
• Single-cell lithium-ion or lithium-polymer battery systems
• Industrial devices operating in extended temperature environments

Battery Chargers Procurement Notes

Verify component authenticity through authorized channels due to the availability of counterfeits. Confirm that the specific suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing I2C bus protocols and check for any recent product change notices regarding manufacturing updates or obsolescence status before finalizing procurement plans.

Battery Chargers Selection Notes

Select this component when a compact solution with integrated power switches is required for single-cell charging. The I2C interface allows for dynamic adjustment of charging profiles compared to fixed-resistor alternatives. Consider the 20-DSBGA footprint constraints and verify that the input voltage source remains within the specified 4V to 6V operational window for optimal efficiency and stability.

Battery Chargers Part Context

This part belongs to the BQ2415x family of battery chargers from Texas Instruments. It shares architectural similarities with models like the BQ24151 and BQ24152, differing primarily in specific parameter configurations or suffix designations. The family targets applications needing efficient, space-constrained charging solutions with digital control capabilities.

Battery Chargers Replacement Considerations

Publicly confirmed substitutes include BQ24151AYFFR and BQ24152YFFR. Verify pin-to-pin compatibility and identical electrical specifications before substitution. Cross-reference datasheets to ensure functional equivalence in terms of interface requirements and thermal performance.
