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 port is protected against connection to typical 24VDCor 24VACsystems with a max data line protection of ±40.7V and power/ground line protection up to ±50V.VBUS, 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 VBUSand GND, allowing for the lowest possible insertion loss while providing high ESD and Burst protection.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.Design Solution: Protecting Your USB Port Doesn’t Have to Slow It Down ›ApplicationsDiagnostic USB portIndustrial PCProgrammable Logic Controller (PLC)
