For normal continuous operation. A higher T
j
is allowed as an overload condition but at the threshold T
j(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 T
j
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.
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 R
ON
tests are continuous. The specified pulse duration t
p
refers only to the applied load current.
