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 Rever 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 rever load current. The internal ground resistor limits the rever battery ground current.
Power is dissipated and the T j rating must be obrved.
3 To limit currents during rever battery and transient overvoltages (positive or negative).
4 Of the output power MOS transistor.

1 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load.
怎样说好普通话2 On-state resistance is incread 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 purpos only. This parameter will not be characterid for automotive PPAP.
7 The supply and input voltage for the R
ON tests are continuous. The specified pul duration t
p
refers only to the applied load current.
