IRSM836-045MA
4A, 500V
Integrated Power Module for
Small Appliance Motor Drive Applications
Description
IRSM836-045MA is a 4A, 500V Integrated Power Module (IPM) designed for advanced appliance motor drive
applications such as energy efficient fans and pumps. IR's technology offers an extremely compact, high
performance AC motor-driver in an isolated package. This advanced IPM offers a combination of IR's low RDS(on)
Trench MOSFET technology and the industry benchmark 3-phase high voltage, rugged driver in a small PQFN
package. At only 12x12mm and featuring integrated bootstrap functionality, the compact footprint of this surfacemount package makes it suitable for applications that are space-constrained. Integrated over-current protection,
fault reporting and under-voltage lockout functions deliver a high level of protection and fail-safe operation.
IRSM836-045MA functions without a heat sink.

IRSM836-045MA
Fault Reporting and Programmable Fault Clear Timer
The IRSM836-045MA provides an integrated fault reporting output and an adjustable fault clear timer.
There are two situations that would cause the IRSM836-045MA to report a fault via the FAULT pin. The first is an
under-voltage condition of VCC and the second is when the ITRIP pin recognizes a fault. Once the fault condition
occurs, the FAULT pin is internally pulled to VSS and the fault clear timer is activated. The fault output stays in the
low state until the fault condition has been removed and the fault clear timer expires; once the fault clear timer
expires, the voltage on the FAULT pin will return to VCC.
The length of the fault clear time period (tFLTCLR) is determined by exponential charging characteristics of
the capacitor where the time constant is set by RRCIN and CRCIN. In Figure 4 where we see that a fault condition
has occurred (UVLO or ITRIP), RCIN and FAULT are pulled to VSS, and once the fault has been removed, the
fault clear timer begins. Figure 5 shows that RRCIN is connected between the VCC and the RCIN pin, while CRCIN is
placed between the RCIN and VSS pins.

1. Electrolytic bus capacitors should be mounted as close to the module bus terminals as possible to reduce
ringing and EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins
will further improve performance.
2. In order to provide good decoupling between VCC-VSS and VB1,2,3-VS1,2,3 terminals, the capacitors
shown connected between these terminals should be located very close to the module pins. Additional
high frequency capacitors, typically 0.1µF, are recommended.
3. Value of the boot-strap capacitors depends upon the switching frequency. Their selection should be made
based on application note AN-1044.
4. PWM generator must be disabled within Fault duration to guarantee shutdown of the system. Overcurrent condition must be cleared before resuming operation.

Current Capability in a Typical Application
Figure 6 shows the current capability for this module at specified conditions. The current capability of the
module is affected by application conditions including the PCB layout, ambient temperature, maximum PCB
temperature, modulation scheme, PCB copper thickness and so on. The curves below were obtained from
measurements carried out on the IRMCS1471X_R4-1 reference design board which includes the IRSM836045MA and IR’s IRMCK171 digital control IC.

PCB Example
Figure 7 below shows an example layout for the application PCB. The effective area of the V+ top-layer
copper plane is ~3cm² in this example. For an FR4 PCB with 1oz copper, Rth(J-A) is about 40°C/W. A lower Rth(J-A)
can be achieved using thicker copper and/or additional layers.
Module
Figure 7: PCB layout example and corresponding thermal image (16kHz, 2P, 1oz, ∆Tca=70°C, V+ = 320V, Iu = 417mArms,
Po = 93W)
At the module’s typical operating conditions, dV/dt of the phase node voltage is influenced by the load
capacitance which includes parasitic capacitance of the PCB, MOSFET output capacitance and motor winding
capacitance. To turn off the MOSFET, the load capacitance needs to be charged by the phase current. For the
IRMCS1171 reference design, turn-off dV/dt ranges from 2 to 5 V/ns depending on the phase current magnitude.
Turn-on dV/dt is influenced by PCB parasitic capacitance and motor winding capacitance and typically ranges
from 4 to 6 V/ns. The MOSFET turn-on loss combined with the complimentary body diode reverse recovery loss
comprises the majority of the total switching losses. Two-phase modulation can be used to reduce switching
losses and run the module at higher phase currents.
