• Capable of operating with high input supply voltages up to 60V for direct connection to higher voltage sources.
• Features programmable constant current charging control with timer-based termination.

Battery Chargers Applications

• Charging systems for industrial equipment requiring high-voltage battery inputs
• Power management in telecommunications infrastructure using lead-acid or lithium batteries
• Backup power units utilizing lithium polymer or LiFePO4 cells

Battery Chargers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal pad configuration. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the DFN-10 footprint matches your PCB design guidelines. Check for any product change notifications regarding manufacturing site or material composition updates.

Battery Chargers Selection Notes

Select this component when the application requires a single-chip solution for high-voltage battery charging without external switching regulators. Consider the thermal performance of the DFN-10 package relative to the maximum 250mA output current. Verify that the required battery chemistry is supported by the internal charge algorithm. Evaluate the need for external components to set the precise charging current and voltage parameters.

Battery Chargers Part Context

This part belongs to the LTC4079 series of linear charge managers from Analog Devices. It is distinct from switching regulators like the LT3479 or other buck converters in the portfolio. The IDD suffix indicates a specific temperature range and package variant within the broader LTC4079 family, differentiated from the EDD version primarily by operational specifications or packaging details defined in the datasheet.

Battery Chargers Replacement Considerations

LTC4079EDD#PBF is a related variant within the same series. Verify functional equivalence and pin compatibility before substitution. No other direct cross-model replacements are confirmed in public documentation.
