5.3 Over Current Operation This IC detects over current by checking the Voltage drop at the external resistance RS. When
typ 200kW VB typ 220kW typ 5pF Vref S Latch R
the input voltage at RS terminal exceeds the internal reference voltage (Vref), this IC turns off the output of all arms circuit and F terminal output becomes "L". After over current detection, reset is done when all six inputs are referenced to high level. In case of not using this function, please connect this terminal to GL terminal (within 100 W).

5.4 Undervoltege Detection 1) When Vcc supply voltage becomes below Vuvb(11.4V typ.), all of the IGBTs shut off and F terminal output becomes "L". 2) When between BU-MU, BV-MV or BW-MW voltage become below Vuvt(11.4V typ.), top arm IGBT of under voltage detected phase shuts off. In this time, F terminal output doesn't change. Note 1. When VCC supply voltage becomes lower, driving capability of IGBT also becomes lower. Accordingly, power dissipation becomes higher and this causes temperature raise of IC. In case of junction temperature exceeds 135C, IC may deteriorate or breakdown.
