BQ24120RHLT

Battery Chargers Overview

The BQ24120RHLT is a synchronous switch-mode single-cell lithium-ion battery charger manufactured by Texas Instruments. It integrates a 2A power FET and operates within an input voltage range of 4.35V to 16V, with an absolute maximum rating of 20V. The device supports adjustable charge current and termination timer settings via external resistors. It utilizes a 20-pin VQFN package (3.5x4.5mm) and functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates a synchronous buck converter with a built-in 2A power FET for efficient charging.
• Features enhanced electromagnetic interference (EMI) performance through spread-spectrum frequency modulation.
• Includes comprehensive protection mechanisms such as overvoltage protection and thermal monitoring via a dedicated thermistor pin.

Battery Chargers Applications

• Portable consumer electronics requiring single-cell Li-Ion or Li-Polymer battery management
• Handheld devices and mobile communication equipment
• Medical instrumentation utilizing rechargeable batteries

Battery Chargers Procurement Notes

Verify the specific suffix RHLT confirms the 20-VQFN package and tape-and-reel packaging format. Ensure compatibility with RoHS3 standards and check moisture sensitivity level classifications for surface-mount assembly processes. Confirm lead-free status if required by specific environmental regulations.

Battery Chargers Selection Notes

Select this component for applications prioritizing high efficiency and compact footprint in single-cell charging systems. The integrated FET reduces external component count compared to linear chargers. Consider the EMI benefits for noise-sensitive environments. Validate that the 16V input limit aligns with the system's power supply architecture.

Battery Chargers Part Context

This part belongs to the bqSWITCHER family of battery chargers from Texas Instruments. It shares architectural similarities with the BQ24125 but is optimized specifically for single-cell configurations. The series emphasizes space-saving designs and improved electromagnetic compatibility for modern portable devices.

Battery Chargers Replacement Considerations

The BQ24125 serves as a functional alternative within the same family, offering similar switch-mode capabilities. Verify package compatibility and control interface requirements before substitution. Cross-reference datasheets to ensure equivalent thermal and electrical performance characteristics match the design constraints.
