Set S1=ON, V1=V2=3.6V, and V3=0V under normal condition and measure current consumption. Current
consumption I1 is the normal condition current consumption (IDD). Set S1=OFF, V1=V2=1.5V under
overdischarge condition and measure current consumption. Current consumption I1 is the power-down
current consumption (IPD).
Set S1=ON, V1=V2=V3=1.5V, and V3=2.5V under overdischarge condition. (V1+V2-V3)/I2 is the internal
resistance between VCC and VM (RVMD). Set S1=ON, V1=V2=3.5V, and V3=1.1V under overcurrent
condition. V3/I2 is the internal resistance between VSS and VM (RVSM).
Set S1=ON, S2=OFF, V1=V2=3.6V, and V3=0V under normal condition. Increase V4 from 0V gradually.
The V4 voltage when I1 = 10µA is DO 'H' voltage (Voh2). Set S1=OFF, S2=ON, V1=V2=3.6V, and
V3=0.5V under overcurrent condition. Increase V5 from 0V gradually. The V5 voltage when I2 = 10 µA is
the DO 'L' voltage (Vol2).
