Note ; Ringing happens around the point where the signal output
voltage changes state from “analogue” to “data hold” due
to test circuit arrangement and instrumentational trouble.
Therefore, the rate of change is measured at a 5 µs delayed point.

Note : Input interlock protection circuit ; It is operated when the input signals for any upper-arm / lower-arm pair of a phase are simulta-
neously in “LOW” level.
By this interlocking, both upper and lower IGBTs of this mal-triggered phase are cut off, and “FO” signal is outputted. After an “input
interlock” operation the circuit is latched. The “FO” is reset by the high-to-low going edge of either an upper-leg, or a lower-leg input,
whichever comes in later.

Note : Short circuit protection operation. The protection operates with “FO” flag and reset on a pulse-by-pulse scheme. The protection by
gate shutdown is given only to the IGBT that senses an overload (excluding the IGBT for the “Brake”).
