1 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 ensure that the input and status currents do not exceed the limiting values.
The internal ground resistor limits the reverse battery ground current. The connected loads must limit the reverse load currents. Power
is dissipated and the T j rating must be observed.
3 To limit currents during reverse battery and transient overvoltages (positive or negative).
