The MAX22505 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX22505 ±40V USB port protector.
The EV kit consists of 3 independent sections: A highpower peripheral section, a low-power peripheral section, and a high-power host section. Each section demonstrates protecting a USB bus from overvoltage conditions on the USB lines.
The high-power peripheral section adds external MOSFET switches to the low-power peripheral circuit, reducing losses to power delivered to the peripheral.
The EV kit powers completely from the USB host, such as a laptop, and requires no other power source. For peripheral applications, an isolated supply is offered for convenience but is not necessary in customer applications. Test access points are provided to optionally power each circuit section externally.
