[C] Under-Voltage Protection (P-side, UVDB)
c1. Control supply voltage VDB rises : After VDB level rises over under voltage reset level (UVDBr), the circuits start to operate when next
input is applied.
c2. Normal operation : IGBT ON and carrying current.
c3. VDB level dips to under voltage trip level. (UVDBt).
c4. P-side IGBT turns OFF in spite of control input signal level, but there is no FO signal output.
c5. VDB level rises over 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.
Input circuit integrates a 3.3kΩ (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 in dimension of width=3mm,
thickness=100µm, length=17mm
Shunt resistor
Please connect GND wiring from VNC terminal
to the shunt resistor terminal as close as possible.
