Start/Stop Sink Current

To simulate the transient characteristics of load to UUT, the critical problems are when and
how the Load starts sinking current to UUT. You may set the conducting voltage Von to
solve the problems. The Load will start or stop sinking current when the UUT output
voltage reaches the Von voltage. You can start sinking current when the load is ON, and the
input voltage is over Von voltage, but stop sinking when the load is OFF, or the input voltage
is below Von voltage. See Figure 3-9 and 3-10 for start and stop sinking current.
There are two operation modes for Von control, latch and non-latch. Latch means that when
voltage is over Von voltage, Load will start sinking current continuously in spite of the input
voltage drop is below Von voltage. Non-latch means that when the input voltage is below
Von voltage, the Load will stop sinking current. The Von voltage and operation mode are
set in configuration.
