Evaluation Kit for the MAX20046

Please check latest availability status for a specific part variant.


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 RON (max) for the BUS and a 3.3Ω RON (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.
