MAX22505 Evalution Kit
General Description
Features
The MAX22505 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX22505
±40V USB port protector.
● Derives Power From a USB Host
● Proven PCB Layout
● Fully Assembled and Tested
The EV kit consists of 3 independent sections: A high-
power 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.
Ordering Information appears at end of data sheet.
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.

MAX22505 Evalution Kit
A MAX258 (U2, U102) transformer driver feeds power to
an isolation transformer (T1, T101), through to a MAX8719
(U3, U103) LDO, providing an isolated 5 volts for the
MAX22505.
Quick Start

MAX22505 EV kit
Laptop with USB port
An indicator (LED2, LED102, LED202) illuminates green
when power is supplied to the corresponding MAX22505
EV kit section.
Standard USB cable (A to B)
High-speed USB peripheral, such as a thumb drive
To provide external power to the high power peripheral
section, move jumper JU3 to the 1-2 position, and provide
isolated 5 volts between TP6 (EXT 5V) and TP7 (GND).
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation before exercising the full
features of the device:
To provide external power to the low power peripheral
section, move jumper JU103 to the 1-2 position, and
provide isolated 5 volts between TP106 (EXT 5V) and
TP107 (GND).
1) Verify that all the jumpers are in their default positions,
as shown in Table 1.
To provide external power to the protected host section,
move jumper JU202 to the 2-3 position, and provide 5 volts
between TP208 (EXT 5V) and TP203 (GND).
2) Using a USB cable, connect a laptop USB port to P1.
3) Connect a thumb drive to P2.
4) Verify that the laptop detects the thumb drive. Transfer
a file to or from the thumb drive.
Fault Indicator LED
The FLTB open-drain output assserts active low when
any overvoltage could be presented to the protected side
(PVBUS, PDP, PDN, GND).
5) Repeat steps 2 through 4, connecting the laptop to
P101 and the thumb drive to P102.
6) Repeat steps 2 through 4, connecting the laptop to
P202 and the thumb drive to P201.
Should this occur, a FAULTindicator illuminates red (LED3,
LED103, LED203) until the overvoltage is removed.
Detailed Description
High Common Mode Indicator LED
The HCMB open-drain output asserts active-low when a
high common mode voltage is present which has caused
the MAX22505 to force USB traffic to full-speed mode.
The MAX22505 EV kit is a fully tested circuit board
demonstrating the capabilities of the MAX22505 ±40V
USB port protector.
Should this occur, an HCMB indicator illuminates red
(LED1, LED101, LED201).
On-Board Isolated Power
The supply power for the MAX22505 shares the same
power domain as the protected side signals. For this
reason, to obtain supply power from the host side, an
isolated supply circuit must be used in the case of the
protected peripherals.
The MAX22505 EV kit defaults to high-speed fallback
enabled. To disable this feature, short the appropriate
jumper (JU1, JU101, JU201) before power-up for the
MAX22505 EV kit. In this case, the corresponding HCMB
LED will remain illuminated until the jumper short is
removed.
