Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ETE+' corresponds to the 16-pin TQFN-EP package and lead-free RoHS compliance status. Confirm that the active-low enumeration feature matches the system design requirements, as this variant includes an internal pullup switch controlled by the ENUM pin. Ensure power supply configurations align with the specified VL and VBUS ranges for proper operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing low-voltage ASICs with USB peripherals requiring full-speed 12Mbps data transfer. The internal pullup resistor controlled by the ENUM pin simplifies hardware design compared to external resistor solutions. Ensure the application environment stays within the -40°C to +85°C operating temperature range and utilizes the specified 3mm x 3mm TQFN footprint.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13481E/MAX13482E/MAX13483E family of USB transceivers. The MAX13481E specifically distinguishes itself by featuring an active-low enumeration input that controls an internal switch for the D+ pullup resistor. This configuration allows for software-controlled connection management, differentiating it from variants that rely solely on external resistors or lack enumeration control.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with MIC2551A and DP1681. Verify functional equivalence regarding the enumeration control mechanism and electrical characteristics before substitution.
