Under-Voltage Protection (P-side, UV
DB
)
C1: Control supply voltage rises – After the voltage level reaches UV
DBr
, the drive circuit begins to work
at the rising edge of the next input signal.
C2: Normal operation – IGBT turn on and conducting current.
C3: Under-voltage trip (UV
DBt
).
C4: IGBT stays off regardless of the control input level, but there is no F
O
signal output.
C5: Under-voltage reset (UV
Dr
).
C6: Normal operation – IGBT turn on and conducting current.

Wiring inductance should be less than 10nH.
This GND wiring from V

DIP-IPM
NOTE: RC coupling at each input
(parts shown dotted) may change
depending on the PWM control
scheme used in the application
and the wiring impedance of the
printed circuit board. The DIP-IPM
input signal section integrates a
2.5kΩ (min) pull-down resistor.
Therefore,
when using an external
filtering resistor, care must be
taken to satisfy the turn-on
threshold voltage requirement.
