Chapter 1 Product Outline
The objective of this document is introducing Fuji IGBT Intelligent-Power-Module
“Small-IPM”.
At first, the product outline of this module is described.
Secondary, the terminal symbol and terminology used in this note and the specification sheet are
explained. Next, the design guideline on signal input terminals and power terminals are shown using its
structure and behavior. Furthermore, recommended wiring and layout, and the mount guideline are given.

• Higher accuracy of short circuit detection contribute to expanding over load operating area.
• Compatible pin assignment, foot print size and mounting dimensions as the 1
st
gen. Small IPM series.
• Product range: 15A – 35A / 600V.
• The total dissipation loss has been improved by improvement of the trade-off between the Collector-
Emitter saturation voltage
V
CE(sat)
and switching loss.
1.2 Built-in drive circuit
• Drives the IGBT under optimal conditions.
• The control IC of upper side arms have a built-in high voltage level shift circuit (HVIC).
• This IPM is possible for driven directly by a microprocessor. Of course, the upper side arm can also
be driven directly. The voltage level of input signal is 3.3V or 5V.
• Since the wiring length between the internal drive circuit and IGBT is short and the impedance of the
drive circuit is low, no reverse bias DC source is required.
• This IPM device requires four control power sources. One is a power supply for the lower side IGBTs
and control ICs. The other three power supplies are power supplies for the upper side IGBTs with
proper circuit isolation.
The IPM doesn’t need insulated power supplies for the upper side drive because the IPM has built-in
bootstrap diodes (BSD).
