MAX22505 ±40V High-Speed USB Port Protector

Analog Devices Inc. MAX22505 ±40V High-Speed USB Port Protector protects a USB port on commercial and industrial equipment against faulty or incorrectly wired power supplies. The USB port is protected against connection to typical 24V_DC or 24V_AC systems with a max data line protection of ±40.7V and power/ground line protection up to ±50V. The V_BUS, ground, and connector shield connections can be 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_BUS and GND, allowing for the lowest possible insertion loss while providing high ESD and Burst protection. ADI MAX22505 is housed in a 24-pin, 4x4mm TQFN package with an exposed pad. The MAX22505 is specified for operation over the -40°C to +105°C temperature range.
