BQ2014SN-D120TRG4

Battery Management Overview

The BQ2014SN-D120TRG4 is a gas gauge integrated circuit designed for Nickel-Cadmium (NiCd) and Nickel Metal-Hydride (NiMH) battery packs. It operates with a supply voltage range of 3V to 6.5V and utilizes a serial interface for communication. The device is housed in a 16-SOIC package with a width of 3.90mm. It functions as a fuel gauge monitor, providing state-of-charge information for rechargeable battery systems.

Battery Management Feature Summary

• Provides gas gauge functionality for NiCd and NiMH battery chemistries
• Features a serial interface for system communication
• Includes external charge control capabilities

Battery Management Applications

• Portable electronic devices requiring NiCd/NiMH battery monitoring
• Battery pack management systems
• Rechargeable tool power supplies

Battery Management Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with lead-free specifications. Confirm the SOIC-16 package type matches your PCB footprint requirements. Ensure the operating temperature range of 0°C to 70°C aligns with your application environment. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Battery Management Selection Notes

Select this component when managing NiCd or NiMH batteries rather than Lithium-ion types. The serial interface requirement must be supported by the host microcontroller. The 3V to 6.5V supply range dictates the system voltage architecture. Consider the external charge control feature if integrated charging logic is needed within the gauge circuit.

Battery Management Part Context

This part belongs to Texas Instruments' BQ2014 series of battery gas gauges. It is functionally similar to the BQ2012SND107 but tailored for specific NiCd/NiMH applications. The D120 variant indicates specific calibration parameters for capacity tracking. The G4 suffix denotes environmental compliance and manufacturing updates compared to earlier versions.

Battery Management Replacement Considerations

The BQ2014SN-D120TR is a non-G4 version of the same functional device. Verify if the lead-free status is critical for your assembly process. No direct cross-model substitutes from other manufacturers are confirmed in public documentation.
