Current Regulation/Management Procurement Notes

Verify the specific suffix 'EXS' against official datasheets to confirm package type and temperature grade. Confirm RoHS3 compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure ESD handling protocols are followed during assembly due to the small form factor.

Current Regulation/Management Selection Notes

Select this component when a low-profile current limit switch is required for 5V or 3.3V logic systems. Consider the 100mA output limit and 1 Ohm on-resistance for voltage drop calculations. Evaluate the SC-70-4 footprint constraints against PCB layout requirements. Compare thermal dissipation capabilities against expected load currents.

Current Regulation/Management Part Context

This part belongs to the MAX4788 series of current-limit switches. It serves as a protective element in power distribution networks. The device integrates control logic and power FETs into a single monolithic structure. It is designed to replace discrete transistor solutions in space-constrained applications.

Current Regulation/Management Replacement Considerations

Consult the MAX4785-88 datasheet for potential family alternatives. Verify pinout compatibility before substituting with other MAX47xx variants. Cross-reference package dimensions if using different suffixes.
