MAX3345EEBE+T

Overview

The MAX3345EEBE+T is a USB transceiver in a 4x4 UCSP package, operating from -40°C to +85°C. It supports full-speed (12Mbps) USB 2.0 operation with an internal 1.5kΩ pullup resistor. The device features ±15kV ESD protection on D+, D-, and VCC. Logic supply voltage (VL) ranges from 1.65V to 3.6V, while the USB-side supply (VCC) operates between 4.0V and 5.5V. Suspend mode reduces current to under 40µA. The USB_DET threshold for the MAX3345E is 1V to 2.8V.

Feature Summary

• Built-in ±15kV ESD protection on USB I/O pins
• Internal linear regulator allows direct powering from USB
• Enumerate input enables software-controlled USB connection
• USB detect function signals bus insertion events

Applications

• Cell Phones
• PC Peripherals
• PDAs
• MP3 Players
• Digital Cameras

Procurement Notes

Verify the component authenticity by checking the marking code against official Maxim Integrated documentation. Ensure the UCSP package matches the specified 4x4 footprint dimensions. Confirm that the suffix '+T' indicates tape-and-reel packaging as defined in the ordering information section of the datasheet.

Selection Notes

Select this part when low-voltage ASIC compatibility is required due to the VL range down to 1.65V. The MAX3345E variant is specifically chosen over the MAX3344E when the USB detection threshold must accommodate lower voltage levels, ranging from 1V to 2.8V. Ensure the application requires the miniature UCSP form factor for space-constrained designs.

Part Context

This component belongs to the MAX3344E/MAX3345E family of USB transceivers. It shares functional similarities with other members like the MAX3345EEUE+T but differs in physical packaging. While the EEUE variant utilizes a 16-pin TSSOP, the EBE variant employs a 4x4 UCSP package, offering a significantly smaller footprint for portable electronics.

Replacement Considerations

The MAX3345EEUE+T serves as a pin-compatible alternative if a larger package is acceptable. Verify that any substitute maintains the same 1.65V to 3.6V logic supply range and 12Mbps data rate capability. Ensure the replacement also provides ±15kV ESD protection on the differential data lines.
