Under-Voltage Protection (P-side, UVDB)
c1: Control supply voltage VDB rises – After VDB level reaches under voltage reset level (UVDBr),
the circuits starts to operate when next input is applied.
c2: Normal operation – IGBT turns on and carries 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 reaches UVDBr.
c6: Normal operation – IGBT on and carries current.

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 DIPIPM input signal
section integrates a 2.5k (min)
pull-down resistor. Therefore, when
using an external filtering resistor, care
must be taken to satisfy the turn-on
threshold voltage requirement.

It is recommended to make the inductance under 10nH.
For shunt resistors, it is recommended to use as low
inductance type as possible.
Shunt
Resistors
Connect the wiring from VNC terminal at the point as
close to shunt resistors’ terminal as possible.
It is recommended to divide the wiring to current detecting
circuit at the point as close to shunt resistor’s terminal as
possible.
