1 For normal continuous operation. 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 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 Tj rating must be observed.
3 To limit currents during reverse battery and transient overvoltages (positive or negative).

1 Of the output Power MOS transistors.
2 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load. This negative voltage
is clamped by the device.
3 On-state resistance is increased if the supply voltage is less than 7 V.
4 This is the continuous current drawn from the battery when both inputs are low and includes leakage currents to the loads.
5 Per channel but with both channels conducting. Defined as in ISO 10483-1.
6 Equivalent of the parallel connected resistors for both channels.
7 The supply and input voltage for the RON tests are continuous. The specified pulse duration tp refers only to the applied load current.

OPEN CIRCUIT DETECTION CHARACTERISTICS
An open circuit load on either channel can be detected in the off-state. Refer to TRUTH TABLE.
This feature requires external load pull-up to a positive supply voltage via a suitable resistor.

1 Undervoltage sensors causes each channel to switch off and reset.
2 Overvoltage sensors causes each output channel to switch off to protect its load.
3 Above this temperature measurement of these parameters is prevented because OT protection may occur prior to SC protection.
4 SC protection for PD > PD(TO) is latched. Normal operation may only be resumed after the input is toggled low then high again.
Normal operation is maintained as long as PD < PD(TO) and Tj < Tj(TO).
5 Trip time td sc varies with overload dissipation PD according to the exponential model formula td sc ≈ TDSC / LN[ PD / PD(TO) ].
6 After cooling below the reset temperature the channel will resume normal operation.
