*1: If the fluctuation of the power supply is faster than the low-voltage detection time, there is the possibility

to generate or release after the power supply voltage has exceeded the detection voltage range.

*2: This time is to start the slope detection at next power on after power down and internal charge loss.

Notes:

−

Power supply input procedure

Power supply should input same time VCC5 and VCC12, or VCC5 to up step.

Also, when power supply input, VCC12 is not over voltage of VCC5.

−

Power supply shutdown procedure

Power supply should shutdown same time VCC5 and VCC12, or VCC12 to up step.

Also, when power supply shutdown, VCC12 is not over voltage of VCC5.

−

Notes: When power supply input and power supply shutdown

When power supply input, power supply voltage until achieve to recommend operation guarantee

area, same time input for NMIX pin + RSTX pin.

When power supply shutdown, power supply voltage until achieve to recommend operation

guarantee area, same time input for NMIX pin + RSTX pin.
