Under-Voltage Protection (Upper-side, UV

)
C1: Control supply voltage rises – After the voltage level reaches UV
DBr
, 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 (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.

Wiring inductance should be less than 10nH.
(Equivalent to the inductance of a copper pattern with
length = 17mm, width = 3mm, and thickness = 100

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.
