BQ2000TSN-B5TRG4

Battery Chargers Overview

The BQ2000TSN-B5TRG4 is a programmable multi-chemistry fast-charge management integrated circuit manufactured by Texas Instruments. Designed for NiCd and NiMH battery systems, it supports one to four cells in series. The device features programmable charging current, voltage, and timer settings to accommodate various battery chemistries. It operates within a supply voltage range of up to 6V and functions reliably across an ambient temperature range of -20°C to 70°C. The component is housed in an 8-SOIC surface-mount package with a width of 3.90mm.

Battery Chargers Feature Summary

• Supports programmable charging parameters including current, voltage, and timer for flexible battery management
• Compatible with multiple battery chemistries, specifically Nickel-Cadmium and Nickel-Metal Hydride
• Capable of managing single-cell to four-cell series battery configurations

Battery Chargers Applications

• Portable electronic devices requiring NiCd or NiMH battery charging
• Power tools utilizing rechargeable nickel-based battery packs
• Uninterruptible power supply (UPS) systems with backup nickel batteries
• Medical equipment powered by rechargeable nickel-cadmium cells

Battery Chargers Procurement Notes

Verify the exact suffix against the manufacturer's latest documentation to confirm pinout and electrical specifications. Confirm RoHS3 compliance status as indicated in official datasheets. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements before integration into the design.

Battery Chargers Selection Notes

Select this component when designing circuits for nickel-based battery chemistries requiring adjustable charge profiles. It is suitable for applications needing support for up to four series-connected cells. Consider the operating temperature range and supply voltage limits relative to the system environment. Evaluate the need for programmable features versus fixed-parameter alternatives based on design flexibility requirements.

Battery Chargers Part Context

This part belongs to the BQ2000 family of battery chargers from Texas Instruments. The family includes variants such as the BQ2000T and BQ2002C, which share similar multi-chemistry management capabilities. The BQ2000 series is distinct from lithium-ion specific chargers like the BQ24100, focusing instead on the unique termination criteria required for nickel-based cells.

Battery Chargers Replacement Considerations

The BQ2000SN-B5TR is a related variant within the same product family. Verify compatibility regarding package type and electrical characteristics before substitution. Consult the manufacturer's replacement guide for any obsolescence notices or recommended upgrades.
