Under-Voltage Protection (Upper-side, UVDB)
C1: Control supply voltage rises – After the voltage level reaches UVDBr, 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 (UVDBt).
C4: IGBT stays off regardless of the control input level, but there is no FO signal output.
C5: Under-voltage reset (UVDr).
C6: Normal operation – IGBT turn on and conducting current.
Typical Interface Circuit
Wiring Method Around Shunt Resistor
VNC N
DIP-IPM
Wiring inductance should be less than 10nH.
(Equivalent to the inductance of a copper pattern with
length = 17mm, width = 3mm, and thickness = 100um.)
RSHUNT (Chip type resistor is recommended.)
This GND wiring from VNC should be as
close to the shunt resistors as possible.

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 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.
