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). 4 Of the output power MOS transistor.

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.
