Frequently Asked Questions
What battery chemistries does the BQ2002CSN support?
The BQ2002CSN supports NiCd (Nickel-Cadmium) and NiMH (Nickel-Metal Hydride) battery packs. It provides fast-charge control with multiple termination methods including temperature-based dT/dt detection and voltage-based -ΔV detection to ensure safe and complete charging of these chemistries.
How does the BQ2002CSN determine when charging is complete?
The BQ2002CSN uses multiple charge termination methods: negative delta voltage (-ΔV) detection, temperature rate-of-change (dT/dt) monitoring, and an absolute maximum temperature threshold. These combined methods prevent overcharging and ensure battery longevity across different load and environmental conditions.
What package does the BQ2002CSN come in?
The BQ2002CSN is available in an 8-pin SOIC (Small Outline Integrated Circuit) package, which is suitable for surface-mount assembly on PCBs. This compact package makes it easy to integrate into space-constrained portable and handheld device designs.
Where can I buy the BQ2002CSN and what is the price?
The BQ2002CSN is available from authorized distributors and component suppliers starting at approximately $1.29 per unit. FindMyChip offers in-stock inventory with worldwide shipping, making it easy to source this Texas Instruments charger IC for your production or prototype needs.
