When PWMx=HIGH, if the voltage of Source pin becomes lower than 0.15V(typ), ERR_DET = LOW is outputted and RES
SHORT error will be detected, and this error state is realeased when the voltage of Sourse pin comes back to 0.15V(typ) or
higher.
When PWMx=LOW, if the voltage of Source pin becomes higher than 0.15V(typ), ERR_DET = LOW is outputted and RES
SHORT error will be detected, and this error state is realeased when the voltage of Sourse pin comes back to 0.15V(typ) or
lower.
① When PWMx=LOW, If Source pin becomes 0.15V(typ) or more, MOS SHORT error is detected.
② If source pin voltage is release condition, ERR_DET=HIGH is outputted.
③ When PWMx=HIGH, If Source pin becomes 0.15V(typ) or lower, RES SHORT error is detected.
④ If source pin voltage is release condition, ERR_DET=HIGH is outputted.
ERR_DET=LOW is outputted.
ERR_DET=LOW is outputted.
