LTC1559CGN-3.3#PBF

Battery Management Overview

The LTC1559CGN-3.3#PBF is a battery power management integrated circuit designed for nickel-cadmium (NiCd) battery systems, manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features a fixed output voltage of 3.3 V. The device is housed in a 16-lead SSOP package and supports surface-mount installation. It functions as a backup battery controller with specific capabilities for managing NiCd cells.

Battery Management Feature Summary

• Integrated control logic for single-cell nickel-cadmium battery management
• Fixed 3.3 V output capability for system backup applications
• Surface-mount compatible packaging for automated assembly

Battery Management Applications

• Backup battery controllers for portable electronic devices
• Power management for nickel-cadmium battery packs
• System retention circuits requiring stable backup voltage

Battery Management Procurement Notes

Verify the exact suffix and package type against the official Analog Devices datasheet before procurement. Confirm availability status through authorized distributors, as supply constraints may apply. Ensure compatibility with existing PCB footprints for the 16-SSOP package. Validate that the fixed 3.3 V output meets the specific requirements of the target NiCd backup application.

Battery Management Selection Notes

Select this component when a dedicated controller for single-cell NiCd batteries is required. The fixed 3.3 V output simplifies design for systems needing a stable backup rail. Consider the 16-SSOP package size for space-constrained designs. Verify that the operating temperature range and input voltage specifications align with the system's power environment.

Battery Management Part Context

This part belongs to the LTC1559 family of battery power management ICs from Analog Devices. These components are specialized for managing rechargeable battery chemistries, specifically targeting nickel-based cells. The CGN-3.3 variant denotes the commercial grade, SSOP package, and fixed 3.3 V output configuration within this product line.

Battery Management Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible or functionally equivalent alternatives within the LTC1559 series. Verify that any substitute maintains the same NiCd management capabilities and 3.3 V output specification.
