Notes:
*1: If a power fluctuation precedes the low-voltage detection time, the detection may occur or be canceled after the supply voltage
passes the detection voltage range.
*2: If Vcc is held below 0.2 V for a minimum period of t
OFF
, power-on reset will occur. If t
OFF
is not satisfied, power-on reset will still
occur if the power ramp rate is kept below 6 mV/µs.
*3: This is the power ramp rate with which power-on reset will always occur regardless of power-off time, as mentioned in *2.
