Product details

Overview

IRSM515-084PA from Infineon Technologies (formerly International Rectifier) is a 250V, 3-phase integrated power module (IPM) for small-appliance motor drives, featuring 0.45Ω max R_DS(on) at 25°C, 1900V_RMS isolation, and DIP23 package. It integrates six Trench FREDFETs with matched propagation delay (0.7–1.5µs), under-voltage lockout per channel, and 3.3V logic-compatible inputs - deployed in energy-efficient fans and pumps.

For engineers reviewing the IRSM515-084PA datasheet, IRSM515-084PA pinout, IRSM515-084PA application, or IRSM515-084PA equivalent, key selection criteria include its 250V blocking voltage, 4.6A DC output current per MOSFET, dV/dt-optimized EMI performance, open-source shunt sensing capability, and absence of integrated NTC thermistor versus IRSM505-084.

Technical Context

The IRSM515-084PA implements three independent half-bridge HVICs driving high- and low-side Trench FREDFETs in a single DIP23 package. Each channel includes bootstrap-supplied gate drivers with matched turn-on/turn-off propagation delays (±0.2µs typical), UVLO thresholds (7.7–9.8V), and tolerance to negative transient voltage at -Vs.

It supports PWM carrier frequencies up to 20kHz, delivers 15µJ turn-on switching loss at 150V/0.7A, and features optimized dV/dt trade-offs between conduction loss and EMI suppression - critical for compact, fan-cooled appliance inverters where thermal and noise margins are constrained.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	250V - Maximum blocking voltage per MOSFET; enables direct interface with 200V DC bus without external clamping.
RDS(on) max	0.45Ω @ 25°C - Low conduction loss enabling 4.6A continuous output per phase at TC=25°C.
Isolation Voltage	1900V_RMS/1min - Reinforced insulation for safety-critical appliance mains-connected motor drives.
Propagation Delay	0.7–1.5µs - Matched timing across all six channels ensures balanced 3-phase PWM edge alignment and reduced torque ripple.
VCC Operating Range	13.5–16.5V - Stable gate drive supply window compatible with standard 15V industrial rails and tolerant of line variation.
Logic Compatibility	3.3V input threshold - Direct interface with modern MCU GPIOs without level-shifting circuitry.
Thermal Resistance	6.9°C/W (J–C, high-side V-phase) - Enables thermal design with measurable case temperature reference point for overtemperature protection.

Pinout & Package

DIP23 package: 23-pin dual-in-line, creepage-optimized for 250V AC mains isolation, with exposed copper pad on underside for thermal conduction to heatsink or PCB copper pour.

Pin/Terminal	Circuit Role	Design Meaning
1 COM	Logic ground reference	Common return for all low-side sources and control logic; must be isolated from power ground in floating driver topology.
2 VB1–12 VB3	High-side floating supply pins	Bootstrap node connections for each half-bridge; require external 0.1µF + 22µF capacitor network per VB/VCC pair.
3 VCC1–13 VCC3	Low-side & logic supply inputs	15V supply for gate driver ICs and level-shift logic; shared across all three half-bridges.
4 HIN1–14 HIN3	High-side PWM inputs	3.3V-compatible logic inputs controlling upper FETs; include internal filter (200–300ns) for noise immunity.
5 LIN1–15 LIN3	Low-side PWM inputs	Directly drive lower FETs; same filtering and threshold as HIN pins; enable synchronous rectification control.
11 VTH	Thermistor output	Not connected (NC) - distinguishes IRSM515-084PA from IRSM505-084PA which provides NTC feedback at this pin.
17 V+	DC bus positive input	Main high-voltage DC input node; connects to bulk capacitor and motor phase outputs via U/V/W terminals.
18 U/VS1–23 W/VS3	Phase output & floating supply offset	Three motor phase outputs (U, V, W); VSx pins provide floating references for high-side driver biasing and current sensing.

Key Features

Feature	Design Value
Integrated bootstrap diodes	Eliminates need for external bootstrap diodes and reduces BOM count by 3 components per half-bridge.
Open-source shunt sensing	Enables single-shunt or leg-shunt current measurement without additional op-amp circuitry or isolation amplifiers.
Matched propagation delay	Ensures <±0.2µs skew between high- and low-side edges across all phases - critical for minimizing shoot-through risk.
UVLO with hysteresis	1.2V hysteresis prevents oscillation during brown-out conditions; protects MOSFETs from partial turn-on damage.
EMI-optimized dV/dt	Controlled slew rate reduces radiated emissions without requiring external gate resistors or ferrite beads in most fan/pump designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRSM505-084PA	Includes integrated NTC thermistor (R25 = 47kΩ) at Pin 11; otherwise identical electrical specs and pinout.	Required where real-time junction temperature monitoring is needed for thermal derating or fault shutdown.	Select IRSM505-084PA if closed-loop thermal management is implemented; otherwise IRSM515-084PA reduces system cost and simplifies analog front-end.
FAN9612MPX	600V-rated IPM with higher R_DS(on) (0.85Ω), no integrated bootstrap, and SOIC-28 package; requires external gate drivers and UVLO circuitry.	Suitable for universal-input (100–240V AC) appliances but increases board area and component count.	Choose only when 600V blocking is mandatory; IRSM515-084PA offers superior integration and thermal performance for 200V DC bus systems.

Compared with IRSM505-084PA, IRSM515-084PA removes NTC functionality for cost-sensitive, fixed-thermal-margin designs; compared with FAN9612MPX, it delivers higher integration, lower conduction loss, and smaller footprint - making it optimal for 200V DC-fed small-appliance inverters.

FAQ

What is the maximum DC bus voltage supported by IRSM515-084PA?

The IRSM515-084PA supports a recommended maximum DC bus voltage of 200V, with absolute maximum blocking voltage rated at 250V. Operation above 200V risks exceeding safe operating area limits under transient conditions and may compromise long-term reliability. The module is designed for 200V DC-fed appliance inverters, not universal AC-input topologies.

Does IRSM515-084PA require external bootstrap diodes?

No. The IRSM515-084PA integrates bootstrap diodes internally for all three high-side drivers. Only external bootstrap capacitors (0.1µF ceramic + 22µF electrolytic per channel) are required. This eliminates six discrete diodes and associated PCB routing, reducing layout complexity and improving reliability in high-vibration environments.

How is current sensing implemented with IRSM515-084PA?

The module supports open-source shunt sensing via VR1, VR2, and VR3 pins - low-side source nodes for Phases U, V, and W. These pins allow direct connection to a single shunt resistor placed between COM and the low-side sources, enabling either single-shunt or leg-shunt configurations without external isolation or amplification circuitry.

Can IRSM515-084PA be used with 3.3V microcontrollers without level shifters?

Yes. The HIN and LIN inputs have 2.2V positive-going and 0.8V negative-going thresholds, fully compatible with standard 3.3V CMOS logic. No level-shifting circuitry is required, simplifying interface design and reducing component count - confirmed by characterization at V_IN = 0V to 5V and validated in reference designs using iMotion™ digital controllers.
