Procurement Notes
Verify the specific suffix (e.g., +T) against official datasheets to confirm packaging and compliance details. Ensure the source document explicitly identifies the manufacturer as Analog Devices Inc./Maxim Integrated. Cross-reference the part number with authorized distributors to confirm availability status, as some listings may indicate regional sales restrictions or discontinuation.
Selection Notes
Select this component when a single-channel power switch with adjustable current limits between 75 mA and 1.5 A is required. Consider the 2.25 V to 4.5 V input range and TDFN-8 EP package for space-constrained designs. Evaluate the thermal performance within the -40°C to +85°C operating range against system requirements.
Part Context
The MAX4766AETA belongs to the MAX4766 series of power supply support circuits. It is categorized under Power Switch ICs - Power Distribution. Related variants include MAX4766BETA and MAX4766CETA, which share similar functional descriptions but may differ in specific electrical characteristics or packaging options as documented by the manufacturer.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Variants such as MAX4766BETA+T and MAX4766CETA+T exist within the same family; however, direct substitution requires verification of specific parameter compatibility through official datasheets.
