1 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load.  
2 On-state resistance is increased if the supply voltage is less than 9 V. Refer to figure 8.  
3 This is the continuous current drawn from the supply when the input is low and includes leakage current to the load.  
4 The measured current is in the load pin only.  
5 This is the continuous current drawn from the supply with no load connected, but with the input high.  
6 Defined as in ISO 10483-1. For comparison purposes only. This parameter will not be characterised for automotive PPAP.  
7 The supply and input voltage for the RON tests are continuous. The specified pulse duration tp refers only to the applied load current.

1 The battery to load threshold voltage for short circuit protection is proportional to the battery supply voltage. A graph showing VBL(TO) versus  
VBG will be provided in the product specification. After short circuit protection has operated, the input voltage must be toggled low for the  
switch to resume normal operation.  
2 Measured from when the input goes high.  
3 After cooling below the reset temperature the switch will resume normal operation.
