1 For normal continuous operation. A higher T

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).
