The MAX20046 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-battery on the protected HVBUS, as well as short-to-HVBUS and short-to-battery on the protected HVD+ and HVD-. Short-to-GND and overcurrent protection are also provided on the protected HVBUS output to protect the internal BUS power rail from overcurrent faults.

The device features high-ESD protection to ±15kV Air Gap and ±8kV Contact on the protected HVBUS, HVD+, and HVD- outputs.

The device features a 500mΩ (max) USB power switch, and two low on-resistance (R_ON), USB 2.0 data switches. This device also features an enable input, fault output, 10ms fault-recovery time, 1ms overcurrent-blanking time, and integrated overcurrent autoretry.

The MAX20046 is available in a 12-pin lead-free, TQFN-EP package and operate over the -40°C to +105°C temperature range.

Product Details

The MAX20046 evaluation kit (EV kit) demonstrates the MAX20046 automotive Hi-Speed USB 2.0 protector switch IC, featuring overvoltage protection (OVP), electrostatic discharge (ESD) protection, and undervoltage lockout (UVLO)/overcurrent protection (OCP) for automotive USB applications.

The device protects the USB BUS, D+, and D- data lines from overvoltage conditions, such as a short-to-battery and ESD events. UVLO protects the BUS against lowvoltage conditions such as a short-to-ground. The BUS OCP uses a blanking period allowing momentary BUS shorts to be ignored. All faults can be monitored using the active-low FAULT output signal.

The device can pass high-speed USB differential (D+ and D-) signals up to 480Mbps and has a low 500mΩ R_ON (max) for the BUS and a 3.3Ω R_ON (typ) for the D+ and D- lines. The EV kit is powered by the USB BUS. An on-board MAX15007A automotive regulator provides the IN reference voltage. If a 60mA/120mA current threshold is desired, the MAX20046GTC/V+ can be ordered and interchanged with U1.
