INSULATED TYPE
[C] Under-Voltage Protection (P-side, UVDB
)
c1. Control supply voltage VDB rises. After the voltage reaches under voltage reset level UVDBr, IGBT turns on by next ON signal (LH).
c2. Normal operation: IGBT ON and outputs current.
c3. VDB level drops to under voltage trip level (UVDBt).
c4. IGBT of the correspond phase only turns OFF in spite of control input signal level, but there is no FO signal output.
c5. VDB level reaches UVDBr
.
c6. Normal operation: IGBT ON and outputs current.

Keep High-level (no fault output)
[D] Over Temperature Protection (N-side, Detecting LVIC temperature)
d1. Normal operation: IGBT ON and outputs current.
d2. LVIC temperature exceeds over temperature trip level(OTt).
d3. All N-side IGBTs turn OFF in spite of control input condition.
d4. Fo outputs for tFo=minimum 20μs, but output is extended during LVIC temperature keeps over OTt.
d5. LVIC temperature drops to over temperature reset level.
d6. Normal operation: IGBT turns on by next ON signal (LH).
(IGBT of each phase can return to normal state by inputting ON signal to each phase.)
