2nd Notes:
5. Short-circuit protection is functioning only at the low-sides. It would be recommended that the value of the external sensing resistor (R
SC
) should be selected
around 40
in order to make the SC trip-level of about 75A at the shunt resistors (R
SU
, R
SV
, R
SW
) of 0
. For the detailed information about the relationship
between the external sensing resistor (R
SC
) and the shunt resistors (R
SU
, R
SV
, R
SW
), please see Figure 6.
6. The fault-out pulse width t
FOD
depends on the capacitance value of C
FOD
according to the following approximate equation: C
FOD
= 18.3 x 10

x t
FOD
[F]
7. T
TH
is the temperature of thermistor itself. To know case temperature (T
C
), please make the experiment considering your application.
