2.1 Theory of Operation for the OPT4001YMNEVM
The OPT4001 coupon consists of the OPT4001 IC, decoupling capacitor, and 8 pins. The pins create
connections for the power and I

C signals between the coupon and the EVM motherboard. For evaluation
purposes the coupon can be removed from the motherboard to be used with other platforms. The motherboard
also has an unpopulated 5-pin header footprint for easy access to the supply, ground, and I2C lines.
2.2 OPT4001YMNEVM Hardware Overview
The EVM ships with the coupon plugged into the motherboard. If not already assembled, the basic hardware
setup for the OPT4001YMNEVM involves plugging the coupon board into the motherboard socket. Take special
care to make sure the coupon is oriented correctly as shown in
. Also note the warnings below.
Specifically that the flex part of the coupon should not be pressed on. If unplugging and replugging the coupon
into the motherboard, the coupon should only be handled by the rigid part and no part of the flex should be
pressed on. Then connect the USB cable.
CAUTION
This EVM contains a flex PCB on which the OPT4001 IC is mounted. Flex PCBs are sensitive and
should be handled with extra care. Special caution should be give not to press on the flex PCB as
this can cause the EVM to break.
CAUTION
Many of the components on the OPT4001YMNEVM are susceptible to damage by electrostatic
discharge (ESD). Customers are advised to observe proper ESD handling precautions when
unpacking and handling the EVM, including the use of a grounded wrist strap at an approved ESD
workstation.
