1 On-state resistance is increased if the supply voltage is less than 9 V. Refer to figure 8.
2 Defined as in ISO 10483-1.
3 This is the continuous current drawn from the battery when the input is low and includes leakage current to the load.
4 This is the continuous current drawn from the battery with no load connected, but with the input high.
5 The measured current is in the load pin only.
6 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.
