Battery Chargers Procurement Notes

Verify the exact datasheet revision and ordering information directly from Analog Devices official documentation. Confirm that the 12-TQFN package dimensions and thermal requirements match your PCB layout specifications. Ensure compatibility with your system's input voltage range and desired charging current settings before procurement.

Battery Chargers Selection Notes

Select this component when high efficiency is required for single-cell lithium-ion batteries in space-constrained designs. The integrated power path simplifies system design by managing charge current and system load automatically. Consider the external thermistor requirement for temperature monitoring if operating in varying thermal environments.

Battery Chargers Part Context

The MAX1926 belongs to Maxim Integrated's family of switch-mode battery chargers designed for portable electronics. It complements linear chargers by offering higher efficiency at higher input voltages or currents. The ETC+ suffix indicates a lead-free, RoHS-compliant version in a 12-TQFN package suitable for surface-mount assembly.

Battery Chargers Replacement Considerations

Check Analog Devices official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter overlaps before replacing. No specific substitute part numbers are confirmed in public documentation.
