*Notes
Lower side →It outputs FAULT signal with gate signal OFF.
However, it different from the protection operation of upper side, it is automatically reset
about 9 ms later and becomes an operation beginning condition when recovering to the normal
voltage. (The protection operation doesn't latch by the input signal.)
3.When assembling the hybrid IC on the heat sink, tightening torque range is 0.8N・m to 1.0N・m.
