Other (usage precautions)
1. Precaution when turning on the power
As shown in the figure below, start the transfer of the I
2C bus command after factoring in the power-on time (A),
PDWN operation time (B), RESET operation time (C) and command transfer start time (D).
A: Power-on time
This is the time taken from power-on to when the *VDD15 operating supply voltage has reached the lowest level
(1.35V) and operation has stabilized. The power-on-time depends on the characteristics of the power ICs and other
components, so it must be checked separately. With regard to *VDD33 and *VDD15, *VDD15 must be turned on
after *VDD33 has turned on.
B: PDWN operation time
This is the time during which the "L" level must be applied continuously for a period of 10ms or more to the PDWN
pin after the lowest level (1.35V) of the *VDD15 operating supply voltage has been reached and operation has
stabilized.
C: RESET operation time
This is the time during which the "L" level must be applied continuously for a period of 10ms or more to the RESET
pin after the PDWN is released ("H" level).
D: Command transfer start time
At least an interval of 10ms is required from the time the RESET pin is released ("H" level) to the start of command
transfer.
