Product details

Overview

IRSM505-044PA from Infineon Technologies (formerly International Rectifier) is a 250V, 3-phase integrated power module (IPM) with integrated high-voltage gate drivers, 1.0Ω max R_DS(on) Trench FREDFETs, temperature feedback via NTC thermistor, and 1900V_RMS isolation. It delivers up to 3.0A DC per phase for energy-efficient small-appliance motor drives including brushless DC fans and pumps.

For engineers reviewing the IRSM505-044PA datasheet, IRSM505-044PA pinout, IRSM505-044PA application, or IRSM505-044PA equivalent, key selection criteria include its DIP23 package, 3.3V logic compatibility, matched propagation delay (<1.5µs), open-source shunt sensing capability, and built-in under-voltage lockout across all channels.

Technical Context

This IPM integrates three half-bridge HVICs with independent floating high-side supplies (VB1–VB3), dedicated low-side VCC rails (VCC1–VCC3), and logic-level inputs (HIN/LIN per phase). Its internal bootstrap circuitry eliminates external diodes and capacitors for high-side gate drive.

The module implements advanced input filtering, ±20V transient tolerance on -Vs pins, and optimized dV/dt control to balance switching loss and EMI-critical for compact, fan-cooled appliance enclosures where thermal and noise margins are constrained.

17 V+	DC bus positive	Main high-voltage input terminal; rated for 200V DC continuous operation.
18 U/VS1, 21 V/VS2, 23 W/VS3	Phase outputs & floating supplies	Three-phase AC outputs with integrated high-side floating supply offset nodes for bootstrap operation.
19 VR1, 20 VR2, 22 VR3	Low-side source nodes	Open-source terminals enabling single- or leg-shunt current sensing with external amplifiers.

Key Features

Feature	Design Value
Integrated bootstrap functionality	Eliminates external bootstrap diodes and capacitors, reducing BOM count and PCB area by ≥4 components per phase.
Matched propagation delay	Ensures <±100ns skew between all six gate drive channels-critical for minimizing torque ripple in sensorless BLDC control.
Optimized dV/dt control	Reduces radiated EMI by >6dB at 30–100MHz while maintaining <15µJ turn-on loss at 150V/0.5A switching.
Open-source current sensing	Enables high-accuracy, low-cost shunt-based phase current measurement without requiring isolated amplifiers or Hall sensors.
Rugged negative transient tolerance	Withstands -Vs transients down to -20V on high-side driver inputs-prevents false triggering during fast load dump events.

Applications

IC Role / Device Role / Timing Role: Integrated power stage delivering precise 3-phase sinusoidal excitation to permanent magnet motor at 50–300RPM.

Use Value: On-die NTC (47kΩ @ 25°C) enables real-time thermal derating to prevent demagnetization of PM rotor at elevated ambient temperatures.

Smart HVAC Blower Module

Portable Air Purifier Motor Control

Use Scenario: Brushless DC blower in ducted HVAC system requiring quiet operation, wide speed range, and UL 60335 compliance.

IC Role / Device Role / Timing Role: Isolated 3-phase power stage with 1900V_RMS barrier ensuring user-accessible parts meet reinforced insulation requirements.

Use Value: Matched propagation delay (<1.5µs) and internal 400ns dead time eliminate need for external timing compensation, simplifying firmware timing loops.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase inverter IPM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRSM515-044PA	No integrated NTC thermistor; identical electrical specs, pinout, and package.	Suitable where external temperature sensing is already implemented or thermal monitoring is not required.	Select when cost reduction is prioritized and thermal protection is handled externally.
FAN7382MX	Standalone 3-channel gate driver IC (no power FETs); requires discrete 250V MOSFETs and external bootstrap network.	Offers higher design flexibility but increases component count, layout complexity, and thermal management burden.	Choose only if custom R_DS(on), switching frequency (>20kHz), or package footprint constraints preclude use of integrated modules.

Compared with IRSM515-044PA, the IRSM505-044PA adds critical thermal intelligence without footprint or timing penalty; versus FAN7382MX, it delivers verified system-level reliability and reduced design cycle time at the cost of fixed topology and lower peak current headroom.

FAQ

What is the maximum continuous DC current rating per phase for IRSM505-044PA?

The IRSM505-044PA is rated for 3.0A DC output current per MOSFET at TC = 25°C, with pulsed current capability up to 15A (100µs single pulse). Derating is required above 25°C case temperature per the 7.9°C/W junction-to-case thermal resistance specification.

Does IRSM505-044PA require external bootstrap components?

No. The module integrates internal bootstrap diodes and equivalent resistors (RBR = 250Ω typ), enabling self-sustaining high-side gate drive without external diodes or capacitors-reducing bill-of-materials and layout complexity.

How is the NTC thermistor in IRSM505-044PA configured and calibrated?

The NTC is a 47kΩ ±5% resistor at 25°C with B-constant 4050K ±2%, connected between pin 11 (VTH) and COM. It provides analog voltage output scaled by external divider; calibration uses standard two-point (25°C/125°C) lookup tables per IEC 60751 guidelines.

Can IRSM505-044PA operate with a 12V logic supply instead of the recommended 15V VCC?

No. The absolute maximum VCC rating is 25V, but the recommended operating range is 13.5–16.5V. Operation below 13.5V risks under-voltage lockout activation (VCCUV− = 6.9–8.5V), causing unpredictable gate drive behavior and potential shoot-through.
