1 At -40C the maximum may be exceeded for Vbg>25V and tp>200
s because of the high power dissipation. It will not exceed 25A prior to the
operation of the Overtemperature protection.
2 The battery to load threshold voltage for short circuit detection is proportional to the battery supply voltage.
3 Latched protection. After cooling below the threshold temperature the switch will resume normal operation only after the input has been
toggled low.
4 For measurement purposes an Input pulse of 1.5ms is used to ensure device is stabilised in the on state
