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 R
ON
tests are continuous. The specified pulse duration t
p
refers only to the applied load current.
