5.3 Over Current Operation
This IC detects over current by checking the
Voltage drop at the external resistance RS. When
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 135
C, IC may deteriorate or breakdown.

Note1. Over-current detection level is determined by the following equation.

Note2. Current limiting resistance Rb is prevention over current protection from operation at initial
charge. Rb is about determined by the following equation.
ibpeak=Vref / Rs = VCC / Rb
Rb > (
VCC * Rs
) / Vref

Following figure Indicates the evaluation as the reference of the SOA (safetyoperation area) under the
Tj=135
C ( the junction temperature is equal to 135
C) . Dot mark (
) shows the points of the IC destruction.
The plural points under the same voltage Indicates the dispersion of the sample.
In this figure, IM and VM are the current and the voltage at the terminal of motorwiring at the change of
phase (turn on and turn off).
