BQ24012DRCRG4

Battery Chargers Overview

The BQ24012DRCRG4 is a linear single-cell lithium-ion battery charger from the bqTINY family, manufactured by Texas Instruments. It operates within an input voltage range of 3 V to 16.5 V and delivers a programmable charge current up to 1 A. The device regulates the output voltage to 4.2 V for charging Li-Ion or Li-Polymer batteries. It utilizes a QFN-10 (VSON) package with dimensions of 3 mm x 3 mm. The component supports an operating temperature range from -40 °C to +85 °C.

Battery Chargers Feature Summary

• Integrates a power path management solution that prioritizes system load over battery charging when input power is limited.
• Includes thermal regulation circuitry to automatically reduce charge current based on die temperature to prevent overheating.
• Features a dedicated status indicator pin that drives external LEDs to display charge activity and fault conditions.

Battery Chargers Applications

• Portable consumer electronics requiring compact single-cell power solutions
• Handheld medical devices with strict size constraints
• Industrial handheld instruments

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the package type matches the required PCB footprint. Ensure the input voltage source does not exceed the maximum rating during operation.

Battery Chargers Selection Notes

Select this component for applications requiring a small form factor and integrated power path management. It is suitable for systems where input power availability varies and thermal management is critical. Compare against other bqTINY variants if higher current or different package options are needed.

Battery Chargers Part Context

This part belongs to the bqTINY series of battery chargers designed for space-constrained portable devices. It shares functional similarities with the BQ24013 and BQ24014 but may differ in specific configuration pins or feature sets. The G4 suffix typically denotes environmental compliance updates within the same product line.

Battery Chargers Replacement Considerations

The BQ24012DRCR is the non-G4 equivalent. Other members of the bqTINY family such as BQ24013DRCR or BQ24014DRCR may serve as alternatives if pin compatibility and feature requirements align.
