Overview
The BQ2000PN-B5 is a programmable, monolithic integrated circuit designed for the safe management of fast charging in NiCd, NiMH, and Li-Ion battery packs. It supports one to four cells and operates within a supply voltage range up to 6V. The device features peak voltage detection termination and allows programming of charge current, timer, and voltage parameters. It functions across an operating temperature range of -20°C to 70°C and is housed in an 8-pin PDIP package.
Feature Summary
- Supports multi-chemistry battery types including NiCd, NiMH, and Li-Ion
- Enables programmable charge current, timer, and voltage settings
- Utilizes peak voltage detection for charge termination
Applications
- NiCd battery pack charging
- NiMH battery pack charging
- Li-Ion battery pack charging
Procurement Notes
Verify the specific suffix 'B5' against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure the procurement channel provides documentation confirming the component meets RoHS3 standards. Cross-reference the 8-pin PDIP package dimensions with your PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when designing systems requiring flexible charge profiles for multiple battery chemistries. The programmable nature allows adaptation to various cell configurations without hardware changes. Consider the 8-pin PDIP package for through-hole assembly needs or prototyping environments where surface-mount options are less suitable.
Part Context
This part belongs to the BQ2000 family of battery chargers from Texas Instruments. It serves as a switch-mode multi-chemistry charger IC. The PN variant specifically denotes the PDIP package format, distinguishing it from SOIC versions like the BQ2000SN-B5TR while maintaining identical electrical functionality.
Replacement Considerations
The BQ2000SN-B5TR offers equivalent electrical performance but utilizes an 8-SOIC surface-mount package instead of the PDIP form factor. Verify that the target application board supports the required package type before substituting.
