Product details

Overview

IRSM515-035 from Infineon Technologies (formerly International Rectifier) is a 500V, 3-phase integrated power module (IPM) for small-appliance motor drives, featuring 2.2Ω max R_DS(on) at 25°C, 1900V_RMS isolation, and 3.3V logic-compatible inputs. It integrates six Trench FREDFETs with matched propagation delay (0.8–1.5µs), under-voltage lockout on all channels, and optimized dV/dt for low EMI in fan and pump inverters.

For engineers reviewing the IRSM515-035 datasheet, IRSM515-035 pinout, IRSM515-035 application, or IRSM515-035 equivalent, key selection criteria include its 500V blocking voltage, 2.1A DC output current per MOSFET, SOP23 package thermal resistance (6.9°C/W), bootstrap-integrated gate driver architecture, and absence of NTC thermistor-distinguishing it from IRSM505-035.

Technical Context

The IRSM515-035 implements three independent half-bridge HVICs driving high- and low-side Trench FREDFETs in a single SOP23 package. Each channel features matched turn-on/turn-off propagation delay (typ. 0.8–1.5µs), 400ns internal deadtime insertion, and ±20V high-side floating supply offset tolerance (VS1/2/3).

It operates with 13.5–16.5V V_CC, supports PWM carrier frequencies up to 20kHz, and delivers 24µJ turn-on switching energy at 320V/0.5A (25°C). Its open-source configuration enables both single-shunt and leg-shunt current sensing without external circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Blocking Voltage	500V - supports 400V DC bus operation with 100V margin for transients
R_DS(on) (max, 25°C)	2.2Ω - determines conduction loss in 2.1A continuous motor phase current

IC Role / Device Role / Timing Role: 3-phase inverter delivering 2.1A RMS phase current with <1.5µs inter-channel delay matching.

Use Value: Enables >85% system efficiency at partial load via low R_DS(on) and optimized dV/dt EMI profile.

Use Scenario: Ducted HVAC blower requiring compact, thermally robust motor drive in confined space.

IC Role / Device Role / Timing Role: Integrated gate driver + FETs replace discrete half-bridge designs, reducing BOM count by 12 components.

Use Value: 6.9°C/W junction-to-case resistance allows direct PCB thermal coupling, eliminating dedicated heatsink.

Smart Washing Machine Drum Motor

Low-Noise Refrigerator Compressor

Use Scenario: Inverter-driven drum motor with torque control across 0–1200 RPM range.

IC Role / Device Role / Timing Role: Provides isolated 3-phase output with 400ns internal deadtime to prevent shoot-through during commutation.

Use Value: Low EMI design reduces conducted emissions below CISPR 14-1 Class B limits without added ferrites.

Use Scenario: Hermetic compressor drive requiring high reliability and thermal stability over 15-year lifetime.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRSM505-035PA	Includes integrated NTC thermistor (R25 = 47kΩ); otherwise identical electrical specs	Required where real-time junction temperature monitoring is needed for thermal derating	Select IRSM505-035PA if closed-loop thermal protection is mandatory; IRSM515-035 suffices for fixed-derate systems
FAM68126B	600V rating, higher R_DS(on) (3.5Ω), no internal deadtime, requires external bootstrap	Supports higher bus voltages but increases conduction loss and board area	Choose only when 600V blocking is essential and layout space permits discrete bootstrap components

Compared with IRSM505-035PA, IRSM515-035 removes thermistor circuitry to reduce cost and simplify layout where thermal feedback is handled externally; versus FAM68126B, it offers lower R_DS(on), integrated deadtime, and smaller footprint-making it optimal for space-constrained 400V appliance inverters.

FAQ

What is the maximum continuous output current per phase for IRSM515-035?

The IRSM515-035 supports 2.1A DC output current per MOSFET at TC = 25°C, as specified in its Absolute Maximum Ratings table. This value decreases with rising case temperature-e.g., derated to ~1.3A at TC = 100°C-based on its 6.9°C/W junction-to-case thermal resistance and 150°C max junction temperature limit.

Does IRSM515-035 require external bootstrap capacitors?

No. The IRSM515-035 integrates bootstrap diodes and supports standard external bootstrap capacitors (typically 0.1µF ceramic) connected between VBx and VSx pins. Unlike fully self-bootstrapping modules, it does not embed capacitors but eliminates the need for external bootstrap diodes, simplifying layout and reducing component count.

How does IRSM515-035 differ from IRSM505-035 in thermal monitoring capability?

IRSM515-035 omits the integrated NTC thermistor present in IRSM505-035. Pin 11 (VTH) is NC on IRSM515-035, whereas IRSM505-035 provides a 47kΩ ±5% NTC output referenced to COM, enabling direct analog temperature readback. This makes IRSM505-035 suitable for closed-loop thermal management; IRSM515-035 relies on external sensing or fixed derating.

Can IRSM515-035 operate with a 3.3V microcontroller without level shifters?

Yes. Its HIN/LIN inputs have 2.2V typical positive-going threshold and 0.8V negative-going threshold, making them fully compatible with 3.3V CMOS logic. Input bias current is ≤18µA at 3.3V, ensuring minimal loading on MCU GPIOs-no level-shifting circuitry is required for direct interface.
