MAX20044EVKIT#

MAX20044EVKIT# is an evaluation kit (EV kit) circuit that demonstrates MAX20044F automotive USB protector switch IC, featuring overvoltage protection (OVP), electrostatic discharge (ESD) protection, and under-voltage lockout (UVLO)/overcurrent protection (OCP) for automotive USB applications. The IC protects the USB BUS, D+, and D- data lines from overvoltage conditions, such as short-to-battery and ESD events. UVLO protects the BUS against low-voltage 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 IC can pass high-speed USB differential (D+ and D-) signals up to 480Mbps and has a low 90mohm RON(MAX) for the BUS and a 4ohm RON(TYP) for the D+ and D- lines. The EV kit is powered by the USB BUS. An onboard MAX15007A automotive regulator provides the IN reference voltage.

• Protects USB BUS, D+, and D- signals from overvoltages up to 18V and ESD events
• USB BUS undervoltage lockout
• 1.3A (typ) USB BUS overcurrent-protection threshold
• 1ms overcurrent blanking time, passes 480Mbps USB data signals
• Active-low FAULT output signal, USB powered, fully assembled and tested
• Evaluates the MAX20042F, MAX20043F, and MAX20044F ICs in a 16-pin QSOP package
• MAX20044F EV kit can also evaluate the MAX20042F and MAX20043F after IC replacement of U1
