1 On-state resistance is increased if the supply voltage is less than 9 V. Refer to figure 8. 2 Defined as in ISO 10483-1. 3 This is the continuous current drawn from the supply when the input is low and includes leakage current to the load. 4 This is the continuous current drawn from the supply with no load connected, but with the input high. 5 The measured current is in the load pin only. 6 The supply and input voltage for the RON tests are continuous. The specified pulse duration tp refers only to the applied load current.

STATUS CHARACTERISTICS
Tmb = 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 230 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. 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 voltage is 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 goes high. 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 in current limiting until the overtemperature protection operates.
