LTC1729CS8-8.2#TRPBF

Battery Chargers Overview

The LTC1729CS8-8.2#TRPBF is a smart termination controller for lithium-ion battery chargers, manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 30V and supports dual-cell configurations. The device features a fixed output voltage of 8.2V, suitable for two-series Li-ion cells. It integrates trickle charge preconditioning and constant-current/constant-voltage regulation. Packaged in an 8-lead SOIC (Narrow) with a thermal pad, it functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates smart termination logic for precise lithium-ion charging management
• Provides automatic trickle charge preconditioning for deeply discharged batteries
• Supports dual-cell series configurations with fixed 8.2V output target

Battery Chargers Applications

• Lithium-ion battery charger systems
• Portable electronic device power management
• Dual-cell battery pack protection circuits

Battery Chargers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the 8.2V variant matches the required cell count for your application. Check current availability status as supply may be limited. Ensure compatibility with existing PCB footprints for the 8-SOIC package.

Battery Chargers Selection Notes

Select this component for applications requiring dedicated termination control rather than full switching regulation. Compare against other LTC1729 variants if different output voltages are needed. Consider thermal performance requirements due to the SOIC package constraints. Verify input voltage ranges align with the system's power source capabilities.

Battery Chargers Part Context

This part belongs to the LTC1729 family of smart termination controllers designed specifically for lithium-ion battery charging applications. These devices simplify charger design by handling complex charging profiles including trickle, constant current, and constant voltage phases. The family offers various fixed output voltages to accommodate single or dual-cell configurations.

Battery Chargers Replacement Considerations

Direct substitutes include other LTC1729 variants such as LTC1729CS8-8.4#TRPBF for different voltage targets. Cross-reference with LTC1729CS8-4.2#TRPBF for single-cell applications. Ensure pinout and thermal pad configurations remain compatible during substitution.
