1 For normal continuous operation. A higher Tjis allowed as an overload condition but at the threshold Tj(TO) the over temperature trip operates
to protect the switch.
2 Reverse battery voltage is allowed only with external resistors to limit the input and status currents to a safe value. The connected load must
limit the reverse load current. The internal ground resistor limits the reverse battery ground current. Power is dissipated and the Tj
rating must be observed.
3 To limit currents during reverse battery and transient overvoltages (positive or negative).

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 tprefers only to the applied load current.

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.
