Intellimod™ Module

Dual-In-Line Intelligent
Power Module
50 Amperes/600 Volts

Description:

DIPIPMs are intelligent power
modules that integrate power
devices, drivers, and protection
circuitry. Design time is reduced
by the use of application-specific
HVICs and value-added features
such as linear temperature feed­back. Overall efficiency and
reliability are increased by the
use of full gate CSTBT technology
and low thermal impedance.

Features:

 Low-loss, Full Gate
CSTBT IGBTs

 Single Power Supply

 Integrated HVICs

 Direct Connection to CPU

Applications:

 Variable Speed Pumps

 Variable Speed Compressors

 Small Motor Control

Ordering Information:

PS21A79 is a 600V, 50 Ampere
DIP Intelligent Power Module.

R2 330Ω Optional input signal noise filter (Note 11)

Notes:

1) If control GND is connected to power GND by broad pattern, it may cause malfunction by power GND fluctuation.
It is recommended to connect control GND at only a point at which NU, NV, NW are connected to power GND line.

2) To prevent surge destruction, the wiring between the smoothing capacitor and the P-N1 terminals should be as short as
possible. Generally inserting a 0.1µ ~ 0.22µF snubber capacitor C3 between the P-N1 terminals is recommended.

3) The time constant R1,C4 of RC filter for preventing the protection circuit malfunction should be selected in the range of 1.5µ ~ 2µs.
SC interrupting time might vary with the wiring pattern. Tight tolerance, temp-compensated type is recommended for R1,C4.

4) All capacitors should be mounted as close to the terminals of the DIPIPM as possible. (C1: good temperature, frequency
characteristics electrolytic type, and C2 : good temperature, frequency and DC bias characteristic ceramic type are recommended.)

5) It is recommended to insert a Zener diode DZ1 (24V/1W) between each pair of control supply terminals to prevent surge destruction.

6) To prevent erroneous SC protection, the wiring from VSC terminals to CIN filter should be divided at the point D that is close
to the terminal of sense resistor and the wiring should be patterned as short as possible.

7) For sense resistor, the variation within 1% (including temperature characteristics), low inductance type is recommended.
1/8W is recommended, but an evaluation of your system is recommended.

8) To prevent erroneous operation, wiring A, B, and C should be as short as possible.

9) FO output is open drain type. It should be pulled up to the positive side of 5V or 15V power supply with a resistor that limits
FO sink current (IFO) under 1mA. (Over 5.1kΩ is needed and 10kΩ is recommended for 5V supply.)

10) Error signal output width (tFO) can be set by the capacitor connected to the CFO terminal. t

FO(typ)

= CFO / 9.1 x 10-6 (s).

11) Input drive is high-active type. There is a 3.3kΩ pull-down resistor integrated in the IC input circuit. To prevent malfunction, the wiring of each input
should be patterned as short as possible. When inserting the RC filter, make sure the input signal level meets the turn-on and turn-off threshold voltage.
Thanks to HVIC inside the module, connection to the MCU may be direct or with an opto-coupler.
