1 For normal continuous operation. A higher Tj is 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. 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.

1 At -40˚C the maximum may be exceeded for Vbg>25V and tp>200µs because of the high power dissipation. It will not exceed 25A prior to the
operation of the Overtemperature protection.
2 The battery to load threshold voltage for short circuit detection is proportional to the battery supply voltage.
3 Latched protection. After cooling below the threshold temperature the switch will resume normal operation only after the input has been
toggled low.
4 For measurement purposes an Input pulse of 1.5ms is used to ensure device is stabilised in the on state
