*1: If the fluctuation of the power supply is faster than the low-voltage detection time, there is a possibility to generate or release
after the power supply voltage has exceeded the detection voltage range.
*2: Please suppress the change of the power supply within the range of the power-supply voltage regulation to do a low-voltage
detection by detecting voltage (VDL)
*3: For S6J335xxSB or S6J335xxUB or S6J335xxTB or S6J335xxVB option.
*4: For S6J335xxAB or S6J335xxBB or S6J335xxCB or S6J335xxDB or S6J335xxEB or S6J335xxFB or S6J335xxGB or
S6J335xxHB option.
Notes:
− The detection/release threshold values of following LVD channels are potentially below supply range defined in 9.1.2
Recommended operating condition.
LVDH1(VCC5)
LVDH2(VCC3)
− Please use these LVD channels with your own risk.
− Please monitor the external power supplies on the PCB if needed.
− For S6J335xxSB or S6J335xxUB or S6J335xxTB or S6J335xxVB options:
Depending on the threshold setting, LVDH1 can always detect VCC5 low voltage before the supply drops below the level
defined in 9.1.2 Recommended operating condition. Please refer to Product Hardware Manual for available list of LVDH1
threshold settings.
