MAXIM MAX13342E, MAX13345E User Manual

General Description

The MAX13342E/MAX13345E USB-compliant trans­ceivers are designed to minimize the area and external
components required to interface low-voltage ASICs to
USB. The devices comply with USB 2.0 specification for
full-speed-only (12Mbps) operation. The transceivers
include an internal 3.3V regulator, an internal 1.5kΩ D+
pullup resistor, and built-in ±15kV ESD protection cir­cuitry to protect the USB I/0 ports (D+,D-). The
MAX13345E also has internal series resistors, allowing
it to be wired directly to a USB connector.

These devices operate with logic-supply voltages as
low as +2.3V, ensuring compatibility with low-voltage
ASICs. A low-power mode reduces current consump­tion to less than 45µA. An enumerate function controls
the D+ pullup resistor, allowing devices to logically dis­connect while remaining plugged in.

The MAX13342E has controlled output impedance of
2Ω (max) on D+/D-, allowing the use of external switch­es to multiplex two different USB devices onto a single
USB connector. The MAX13345E has 43.5Ω (max)
internal resistors on D+/D- for direct connection to the
USB connector.

The MAX13342E/MAX13345E are equipped with DAT
and SE0 interface signals. These transceivers provide a
USB detection function that monitors the presence of
USB V

BUS

and signals the event.

These devices operate over the extended -40°C to +85°C
temperature range and are available in UCSP™ 2.0mm x

1.5mm and 14-pin TDFN (3mm x 3mm) packages.

UCSP™ is a trademark of Maxim Integrated Products, Inc.

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
