Application information

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 indicationonly. 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 bytypically 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 0.7 V.

6 Overvoltage sensor causes the device to switch off to protect the load. Typical hysteresis equals 1.3 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.

1 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load. This negative voltageis clamped by the device.

2 The load current is self-limited during the response time for short circuit load protection. Response time is measured from when input goeshigh.

3 If the load resistance is low, but not a complete short circuit, such that the on-state voltage remains less than VBL(TO), the device remains incurrent limiting until the overtemperature protection operates.
