MAX14581EWC+T

Drivers, Receivers, Transceivers Overview

The MAX14581EWC+T is a USB-compliant full-speed transceiver designed for low-voltage ASICs. It supports USB 2.0 operation at 12Mbps and features an internal 3.3V regulator, a 1.5kΩ D+ pullup resistor, and ±15kV ESD protection on D+/D-. The device operates with a logic supply (VL) of +1.2V to +3.6V and a VBUS range of +3.0V to +5.5V. It utilizes a 3-wire interface (DAT, SE0, OE) and includes a Bus Detect (BD) pin. Key electrical parameters include a typical disable-mode current of 13µA from VBUS and internal series resistors of 36Ω on D+/D-.

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific 3-wire interface variant (MAX14581) rather than the 5-wire version. Confirm the WLP-12 package type and ensure the ordering suffix corresponds to the tape-and-reel format if required by the manufacturing process. Cross-reference the manufacturer's latest datasheet for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing low-voltage ASICs to USB requires minimizing PCB area and external components. It is suitable for applications needing a full-speed-only transceiver with a logic supply as low as 1.2V. Ensure the design accommodates the 3-wire control signals (DAT, SE0, OE) and utilizes the internal series resistors for direct connector wiring without additional impedance matching components.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Maxim Integrated family of industry-smallest full-speed USB transceivers. It is specifically engineered to reduce the footprint and bill of materials for portable devices. The MAX14581 variant distinguishes itself with a 3-wire interface and a dedicated bus detect pin, catering to designs prioritizing minimal pin count and simplified control logic compared to multi-wire alternatives.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14582 serves as a functional alternative within the same family but utilizes a 5-wire interface (VP, VM, RCV) and lacks the BD pin. Substitution requires adapting the control logic to the different interface signals and verifying compatibility with the existing schematic layout and firmware drivers.
