1 The battery to load threshold voltage for short circuit protection is proportional to the battery supply voltage. A graph showing V_BL(TO) versus
V_BG 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.
