Finally, an external network can be connected across

Vout and ground , but the current through such network will

not be regulated by the NCP5602 chip (see Figure 5). On

top of that, the total current out of the Vout pin shall be

limited to 60 mA.

I2C Protocol

The standard I2C protocol is used to transfer the data

from the MCU to the NCP5602. Leaving aside the

Acknowledge bit, the NCP5602 does not return data back

to the MCU.
