1.0 Introduction
The USB Fixture is a test tool for USB 3.0 interface with multi-functions of
voltage switch, voltage test and current test.
It's especially designed to save valuable labor and time in the production
environment.
The USB Fixture is constructed of high quality components for years of trouble
free service.

3.0 Function
zTest connector for all of signal and power pins
zLED indicates power status
zOver-current protection with power switch IC
zAlternative Output Voltage: 5v to 5v/3.3v
zVoltage can be tested conveniently and directly
zCurrent can be tested conveniently and directly
zExternal power supply support
4.0 Schematic profile
1. IC1 can work as short and over load protection. When external load current
is larger than 500mA, or short output, it will perform protection function.
Meanwhile, LED D3 (R) will show on for warning function.
2. IC2 is a voltage converter with 5V input and 3.3V output.

3. Three pairs of USB test points can test signal working status wholly.
5.0 Application note
zDifferent Voltage switch
Set Jumper Cap on JP1 1-2 position, IC1 can work normally. Set Jumper Cap
on JP2 1-2 position, IC2 cannot work. Meanwhile, LED D2 (G) will show on
and output voltage shows 5V.
Set Jumper Cap on JP1 1-2 position, IC1 can work normally. Set Jumper Cap
on JP2 2-3 position, IC2 can work normally. Meanwhile, LED D1 (Y) and LED
D2 (G) will show on. Output voltage shows 3.3V.

Set Jumper Cap on JP1 2-3 position, IC1 cannot work. Set Jumper Cap on
JP2 1-2 position, IC2 cannot work. Meanwhile, output voltage shows 5V.
Set Jumper Cap on JP1 2-3 position, IC1 cannot work. Set Jumper Cap on
JP2 2-3 position, IC2 can work normally. Meanwhile, output voltage shows
3.3v.
zVoltage test
TP2 is a test point for input voltage 5V. TP3 is a test point for output voltage
Vout. Input voltage can be obtained by measuring TP2 and TP4 (TP1), and
output voltage can be obtained by measuring TP3 and TP4 (TP1).
Vout=5V, test method

Vout=3.3V, test method
zCurrent test
1. Vout=5V, current test method:
Current test method without load I0

Current test method with load I1
So the Load current Iload=I1-I0=30.88mA-0=30.88mA
2. Vout=3.3V, current test method:
Current test method without load I0

Current test method with load I1
So the Load current Iload=I1-I0=43.6mA-13.0mA=30.6mA
zExternal power supply
For USB special voltage supply need, the user can choose external power to
replace USB power supply. Before using, the user must remove Jumper Cap
on JP1 and JP2 position, and ensure TP3 connecting with VOUT, TP4 (TP1)
with GND.
