4.0Ω, 500V
Integrated Power Module for
Small Appliance Motor Drive Applications
Description
IRSM505-025 and IRSM515-025 are 3-phase Integrated Power Modules (IPM) designed for advanced appliance
motor drive applications such as energy efficient fans and pumps. These advanced IPMs offers a combination of
low RDS(on) Trench FREDFET technology and the industry benchmark half-bridge high voltage, rugged driver in a
familiar package. The modules are optimized for low EMI characteristics.
IRSM505-025 includes temperature feedback while IRSM515-025 does not.

Figures 5-7 show the typical current capability for this module at specified conditions. In all tests, the application
board the IRMCS1071-1-D reference board was placed in a box to prevent cooling from ambient airflow.
Figure 5 is derived from using a heat sink that maintains TC at 125°C. Figures 6-7 represent current capability for
the module as used without any heat sink. TJA represents the difference in temperature between the junction of
the high-side V-phase Mosfet and the ambient, measured 10cm above and 6cm away from the board. Ambient
temperature kept within 28-29°C.

Space Vector Modulation, V+=320V, TA=28°C, TJ=98°C
The module contains an NTC connected between COM and the VTH pin which can be used to monitor the
temperature of the module. The NTC is effectively a resistor whose value decreases as the temperature rises.
The NTC resistance can be calculated at any temperature as follows:



An external resistor network is connected to the NTC, the simplest of which is one resistor pulled up to VCC as
shown in Figure 3. The VTH vs NTC temperature, TTH curve for this configuration is shown in Figure 8 below. The
min, typical and max curves result from the NTC having a ±5% tolerance on its resistance and ±2% tolerance on
the B-parameter.
Figure 9 shows the thermistor temperature, TTH plotted against the high-side V-phase junction temperature, TJ for
a module without a heat sink. It is thus advisable to shut down the module when TTH reaches 125°C.
