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. Because of current limiting, this parameter is not applicable.
7 The supply and input voltage for the RON tests are continuous. The specified pulse duration tp refers only to the applied load current.
