CONTROL INPUT
CIRCUIT STATE
C1: Control supply voltage rises – After the voltage level reaches UV DBr , the drive circuit begins to work
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.

R SHUNT (Chip type resistor is recommended.)
Wiring inductance should be less than 10nH.
(Equivalent to the inductance of a copper pattern with
length = 17mm, width = 3mm, and thickness = 100um.)

This GND wiring from V NC should be as
close to the shunt resistors as possible.

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 3.3k Ω
(min) pull-down resistor. Therefore,
when using an external filtering
resistor, care must be taken to
satisfy the turn-on threshold voltage
requirement.
