The above has indicated a part for single arm.
There is no relevance of operation between arms.
When the input of a high side arm and a low side arm is simultaneously set to "L", IGBT of a high side arm and
a low side arm turns off.
FO (X) terminal is turned on in the meantime at the same time, as for the output of Phase which detected the
load short circuit state, it will maintain the OFF between 10ms, if a Short Current Protection detects a Short
Current state. Although an incoming signal is reset by an upper arm and a lower arm being simultaneously set
to "H" in the back in this state, OFF of an output and FO (X) are maintained between 10ms. Although FO (X) is
turned off when FO (X) terminal for 10ms will not be in the simultaneous "H" state of an upper arm and a
lower arm in during ON time, an output maintains OFF. This release is made by an upper arm and a lower
arm being simultaneously set to "H." (Short Current Protection is a non-repetition. When FO (X) turns on,
please turn off the input of all Phase.)
If an Over Temperature Protection circuit detects an Over Temperature state, while the output of Phase which
detected the Over Temperature Protection state is turned off, FO (X) terminal turns it on. This state will return
operation, if temperature falls to Over Temperature Protection detection return temperature (Over
Temperature Protection temperature- Over Temperature Protection hysteresis).
