[12] The battery-to-load threshold voltage for short circuit is approximately proportional to the battery supply voltage.
[13] After cooling below the reset temperature the switch will resume normal operation.
[14] The status output is an open drain transistor and requires an external pull-up circuit to indicate a logic HIGH.

For a high-side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load.
This is the current drawn from the supply when the input is LOW, and includes leakage current to the load.
Defined as in ISO 10483-1. For comparison purposes only.

Undervoltage sensor causes the device to switch off and reset.
Overvoltage sensor causes the device to switch off to protect the load.
