1 The battery to load threshold voltage for short circuit detection is proportional to the battery supply voltage.

2 Latched protection. After cooling below the threshold temperature the switch will resume normal operation only after the input has been

toggled low.

3 For measurement purposes an Input pulse of 1.5ms is used to ensure the device is stabilised in the on state.
