Figure 5. Setpoint Voltage vs. L terminal signal

Note:

4. When the Vgo voltage overcomes this value the MFDC is cancelled

Table 7. FAULT

The following table lists the conditions that cause the fault driver to function (L terminal now switching be-tween

0V and VLSAT. To prevent L flicker, specific faults are required to be present for TDELAY seconds be-fore the

fault driver is activated. This delay is indicated in the table.
