LTC1559CS8-5#PBF

Battery Management Overview

The LTC1559CS8-5#PBF is a single-cell backup battery controller manufactured by Analog Devices Inc. It provides a fixed 5V output, delivering up to 3A during normal operation and 20mA in backup mode. Designed for SOIC-8 surface-mount packages, it manages power switching between main supply and a single Ni-Cd or Ni-MH cell. The device ensures continuous system power during main supply interruptions.

Battery Management Feature Summary

• Provides fixed 5V output with high current capability for normal operation
• Manages automatic switching between main power and single-cell backup battery
• Supports Nickel-Cadmium and Nickel-Metal Hydride battery chemistries

Battery Management Applications

• Embedded systems requiring uninterrupted power supply
• Real-time clock and memory backup circuits
• Industrial control systems with critical data retention needs

Battery Management Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm availability status as distribution channels may list limited stock or end-of-life notices. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Battery Management Selection Notes

Select this component when a fixed 5V output is required without external programming resistors. It is suitable for designs needing simple integration of a single backup cell. Consider thermal performance if operating near maximum current limits in enclosed environments.

Battery Management Part Context

This part belongs to the LTC1559 family of battery management ICs. It is specifically designed for applications where maintaining system uptime during power failures is critical. The fixed output variant simplifies design compared to adjustable versions.

Battery Management Replacement Considerations

Check for LT1579CS8-5#PBF as a potential alternative for multi-chemistry battery management. Verify pinout compatibility and electrical specifications against current design requirements before substitution.
