MAX25400

Automotive Hi-Speed USB 2.0 Protector

General Description

Benefits and Features

The MAX25400 device provides high-ESD and short-cir-

cuit protection for the low-voltage internal USB data and

USB power line in automotive radio, navigation, connectiv-

ity, 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 protec-

tion features include short-to-BUS and short-to-battery on

the protected HVD+ and HVD-, and include a fault output.

● Targeted Features for Optimized USB Performance

• Two R

3.3Ω (typ) USB 2.0 Data Switches

• 480Mbps, 12Mbps, or 1.5Mbps USB 2.0 Operation

• 9ms Fault-Recovery Time

● Robust for the Automotive Environment

• Short-to-Battery and Short-to-BUS Protection on

Protected HVD+ and HVD- Outputs

• Tested to ISO 10605 and IEC 61000-4-2 ESD

Standards

The device features high-ESD protection to ±15kV Air Gap

and ±8kV Contact on the protected HVD+ and HVD- out-

• 12-Pin (3mm x 3mm) TQFN-EP Package

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

• AEC-Q100 Qualified

puts. The device features two low on-resistance (R

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 temper-

ature range.
