3 Power for the SN75LVCP600S EVM

The SN75LVCP600S EVM kit comes with a 9-V DC power supply that fits a standard North American wall

socket.

4 Monitoring the Device Current

One of the highlights of the SN75LVCP600S is the power savings features of the device. To observe

these power saving features this EVM design includes the option of monitoring the current draw of the

device. To enable this feature, the following steps must be taken:

1. Un-install the ferrite bead located at L1.

2. Obtain a 3.3-V power supply (connect current meter in series if power supply does not also display

current, or if greater resolution is needed than the power supply can provide). Connect power supply

3 V to pin 1 of the two pin header JMP1. GND from the power supply can be connected to pin 2 of

header JMP1.
