For input ‘0’ equals low, ‘1’ equals high, ‘X’ equals don’t care.
For status ‘0’ equals low, ‘1’ equals open or high.
For output switch ‘0’ equals off, ‘1’ equals on.
STATUS CHARACTERISTICS
T
= 25 C.
The status output is an open drain transistor, and requires an external pull-up circuit to indicate a logic high.

1
In the on-state, the switch detects whether the load current is less than the quoted open load threshold current. This is for status indication
only. Typical hysteresis equals 140 mA. The thresholds are specified for supply voltage within the normal working range.
2
After cooling below the reset temperature the switch will resume normal operation. The reset temperature is lower than the trip temperature by
typically 10 C.
3
If the overtemperature protection has operated, status remains low to indicate the overtemperature condition even if the input is taken low,
providing the device has not cooled below the reset temperature.
4
After short circuit protection has operated, the input voltage must be toggled low for the switch to resume normal operation.
5
Undervoltage sensor causes the device to switch off. Typical hysteresis equals 0.5 V.
6
Overvoltage sensor causes the device to switch off to protect the load. Typical hysteresis equals 1.1 V.
7
In a fault condition with the pull-up resistor short circuited while the status transistor is conducting.
8
The pull-up resistor also protects the status pin during reverse battery conditions.
