MAX22505

±40V High-Speed USB Port Protector

General Description

The MAX22505 is designed to protect a USB port on

commercial and industrial equipment against damage due

to faulty or incorrectly wired power supplies. The USB

Beneﬁts and Features

● Robust Communications

• Integrated ±50V dc Protection for V

/GND

BUS

• Integrated ±40.7V dc Protection for D+/D-

• Thermal Shutdown Protected

• -40°C to +105°C Operating Temperature

● High Performance

port is protected against connection to typical 24V

24V

systems with a max data line protection of ±40.7V

and power/ground line protection up to ±50V.

• High (480Mb), Full (12Mb), and Low (1.5Mb)

Speed Capable

• 3.0V to 5.5V Supply Voltage

, ground and connector shield connections can be

BUS

configured for any level of ESD, burst, and surge protection

by choosing external components. USB data D+ and

D- are protected by external diode clamps to V

GND, allowing for the lowest possible insertion loss while

providing high ESD and Burst protection.

• 4Ω (typ) V

/D+/D- channel resistance

BUS

and

BUS

• 1Ω (max) GND Channel Resistance

• High-Speed USB Disable Mode Allowing Operation

with High Common Mode Voltages

The MAX22505 is housed in a 24-pin, 4mm x 4mm TQFN

package with exposed pad and is specified for operation

over the -40°C to +105°C temperature range.

● Flexibility

• Transparent to USB Operation Speeds

• Conﬁgurationless USB Host or Device Protection

• Optional External MOSFET driver for V
