I O leak
VD1, VD2(EX, OUT1)
LB11693H
Input the logic states shown in the table so that the output transistor
for the corresponding phase is off.
Set I O to 0.7A when measuring VD1.
Set I O to 1.5A when measuring VD2.
The figure shows the circuit used for measuring OUT1. Use similar
circuits for measurement of the other phases.
After setting the logic state so that the high and low side output
transistors for the corresponding phase are in the off state,
proceed to the measurement itself.
Set the switch SW to position 1 for source transistor leakage
measurement, and to position for sink transistor leakage
measurement.
The figure shows the circuit used for measuring OUT3.
Use similar circuits for measurement of the other phases.
