Battery Chargers Procurement Notes

Verify the specific part number suffix against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements before procurement. Cross-reference datasheet specifications for thermal performance and pinout configurations to avoid integration errors during design implementation.

Battery Chargers Selection Notes

Select this component when a combined battery charger and power backup solution is required. It is suitable for applications where space constraints favor an integrated regulator approach. Consider the 36V input capability and 1.5A output current when sizing the power supply and thermal management components for the target application environment.

Battery Chargers Part Context

This component belongs to the LTC4091 series of battery chargers from Analog Devices. It is distinct from other models like the LTC4089 or LTC4098 by its specific input voltage range and integrated regulator topology. The EDJC package indicates a specific surface-mount footprint used in compact power management designs.

Battery Chargers Replacement Considerations

Direct substitutes include other parts within the LTC4091 family, such as the LTC4091EDJC#TRPBF, which shares identical electrical characteristics but differs in packaging format. Verify pin compatibility and thermal dissipation requirements when considering alternative packages.
