BQ2004EPNG4

Battery Chargers Overview

The BQ2004EPNG4 is a multi-chemistry battery charge management integrated circuit manufactured by Texas Instruments. It supports Nickel Cadmium (NiCd) and Nickel Metal-Hydride (NiMH) battery types. The device operates within a supply voltage range of up to 5.5V and functions in temperatures from -20°C to 70°C. It utilizes a 16-pin Plastic Dual In-Line Package (PDIP) with a width of 0.300 inches (7.62mm). The component provides constant pulsed charging capabilities.

Battery Chargers Feature Summary

• Supports NiCd and NiMH battery chemistries
• Provides constant pulsed charge management
• Operates within standard industrial temperature ranges

Battery Chargers Applications

• Battery management for portable devices using NiCd batteries
• Charge control systems for NiMH battery packs
• Industrial equipment requiring robust battery monitoring

Battery Chargers Procurement Notes

Verify the package type matches the design requirements, as this part uses a PDIP housing which differs from surface-mount variants like SOIC. Confirm the suffix G4 indicates lead-free compliance if required by specific environmental regulations. Ensure the operating temperature range meets the application's thermal constraints before finalizing procurement decisions.

Battery Chargers Selection Notes

Select this component when a through-hole solution is necessary for NiCd or NiMH battery applications. The PDIP package facilitates easier prototyping and manual assembly compared to surface-mount options. Consider the 5.5V maximum supply voltage limit to ensure compatibility with the system power architecture.

Battery Chargers Part Context

This component belongs to the BQ2004 family of battery charge controllers. It serves as a specialized solution for managing rechargeable nickel-based batteries. The EPNG4 designation specifically identifies the PDIP package variant, distinguishing it from other packaging options such as SOIC or TSSOP available within the same functional series.

Battery Chargers Replacement Considerations

The BQ2004ESNTR is listed as a recommended alternative by the manufacturer. Note that the ESNTR variant utilizes an SOIC surface-mount package, requiring PCB layout adjustments compared to the PDIP form factor of the BQ2004EPNG4.
