[C] Under-Voltage Protection (Upper-arm, UVDB)
c1. Control supply voltage rises : After the voltage reaches UVDBr, the circuits start to operate when next input is applied.
c2. Normal operation : IGBT ON and carrying current.
c3. Under voltage trip (UVDBt).
c4. IGBT OFF in spite of control input condition, but there is no FO signal output.
c5. Under voltage reset (UVDBr).
c6. Normal operation : IGBT ON and carrying current.

Note : The setting of RC coupling at each input (parts shown dotted) depends on the PWM control scheme and the
wiring impedance of the printed circuit board.
The DIP-IPM input section integrates a 2.5kΩ (min) pull-down resistor. Therefore, when using an external
filtering resistor, pay attention to the turn-on threshold voltage.

Wiring inductance should be less than 10nH.
Equivalent to the inductance of a copper pattern
with length=17mm, width=3mm,
and thickness=100µm
Shunt resistor
Please make the GND wiring connection
of shunt resistor to the VNC terminal
as close as possible.
