1
The battery to load threshold voltage for short circuit protection is proportional to the battery supply voltage.
A graph showing V
versus
V
will be provided in the product specification.
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.
3
After cooling below the reset temperature the switch will resume normal operation.
