    1 Undervoltage sensor causes the device to switch off and reset. 2 Overvoltage sensor causes the device to switch off to protect its load. 3 The status will continue to indicate OT (even if the input goes low) until the device cools below the reset threshold. Refer to...

  • Page 6: Overload Protection Characteristics

    1 The battery to load threshold voltage for short circuit protection is proportional to the battery supply voltage. After short circuit protection has operated, the input voltage must be toggled low for the switch to resume normal operation. 2 Measured from when the input goes high.
