MAX3452EETE+T

Drivers, Receivers, Transceivers Overview

The MAX3452EETE+T is a USB-compliant transceiver designed to interface low-voltage ASICs with USB devices. It fully complies with USB 1.1 and USB 2.0 specifications, supporting full-speed (12Mbps) and low-speed (1.5Mbps) data rates. The device operates with a logic supply voltage (VL) ranging from +1.65V to +3.6V. It features an integrated linear regulator that outputs VTRM at +3.0V to +3.6V, powered by a VBUS input of +4.0V to +5.5V. Key electrical parameters include ±15kV ESD protection on D+ and D- lines, a typical operating supply current of 10mA at full speed, and a suspend mode current of less than 40µA. The component is housed in a 16-pin Thin QFN-EP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated push-pull bus-detect output that asserts high when VBUS exceeds +4.0V
• Logic-selectable suspend mode for significant power reduction
• Internal linear regulator providing regulated VTRM output
• Built-in ±15kV ESD protection on bidirectional USB bus connections

• PDAs
• PC Peripherals
• Cellular Telephones
• Data Cradles
• MP3 Players

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Confirm availability through authorized distributors as part numbers may have varying lifecycle statuses. Ensure the source document matches the exact manufacturer product number for accurate technical specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a USB transceiver requires a dedicated bus-detection signal to manage power states or sharing modes. It is suitable for designs needing compatibility with low-voltage ASICs due to its wide VL range. Consider the MAX3450E or MAX3451E if enumeration functions or pin compatibility with other manufacturers are required instead of bus detection.

Drivers, Receivers, Transceivers Part Context

The MAX3452E is part of the MAX3450E/MAX3451E/MAX3452E family of USB transceivers manufactured by Analog Devices Inc./Maxim Integrated. While sharing core functionality and pinouts, the MAX3452E is distinguished by its BD output. This differentiation allows system designers to implement hardware-based bus presence detection without additional discrete components.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3450E is noted as pin-compatible with Micrel’s MIC2550A. For direct functional replacements within the same family, consider the MAX3450E or MAX3451E, noting that they lack the BD output feature present in the MAX3452E.
