PT6315
SERIAL COMMUNICATION FORMAT
The following diagram shows the PT6315 serial communication format. The DOUT Pin is an N-channel, open-drain
output pin, therefore, it is highly recommended that an external pull-up resistor (1KΩ to 10KΩ) must be connected to
DOUT.
where: twait (waiting time) ≥ 1 µs
It must be noted that when the data is read, the waiting time (twait) between the rising of the eighth clock that has set the
command and the falling of the first clock that has read the data is greater or equal to 1 µs.
