Automotive Hi-Speed USB 2.0 Protector

Smallest High-Voltage Automotive USB 2 Data Line Protection

Please check latest availability status for a specific part variant.


The MAX25400 device provides high-ESD and short-circuit protection for the low-voltage internal USB data and USB power line in automotive radio, navigation, connectivity, and USB hub applications. The device supports USB Hi-Speed (480Mbps), USB full-speed (12Mbps), and USB low-speed (1.5Mbps) operation. The short-circuit protection features include short-to-BUS and short-to-battery on the protected HVD+ and HVD-, and include a fault output.

The device features high-ESD protection to ±15kV Air Gap and ±8kV Contact on the protected HVD+ and HVD- outputs. The device features two low on-resistance (RON) USB 2.0 data switches.

The MAX25400 is available in a 12-pin lead-free, TQFN-EP package and operate over the -40°C to 105°C temperature range.
