Product details

Overview

IRSM515-044DA2 from Infineon Technologies (formerly International Rectifier) is a 250V, 3-phase integrated power module (IPM) for brushless DC motor drives in small appliances. It integrates six Trench FREDFETs with matched 1.0Ω max R_DS(on) at 25°C, three half-bridge high-voltage gate drivers, bootstrap circuitry, and under-voltage lockout on all channels - deployed in energy-efficient fans and pumps requiring compact, low-EMI inverter stages.

For engineers reviewing the IRSM515-044DA2 datasheet, IRSM515-044DA2 pinout, IRSM515-044DA2 application, or IRSM515-044DA2 equivalent, key selection criteria include its 250V blocking voltage, 3.0A DC output per MOSFET, 3.3V logic compatibility, dV/dt-optimized switching, and DIP23A package with open-source current sensing capability.

Technical Context

The IRSM515-044DA2 implements three independent half-bridge HVICs driving 250V Trench FREDFETs, each with matched propagation delay (0.7–1.5 µs turn-on/turn-off) and integrated bootstrap diodes/resistors (R_BR = 250 Ω). Its driver architecture tolerates −V_S transients and includes advanced input filtering for noise immunity.

Unlike the IRSM505-044 variant, this part omits the NTC thermistor (no VTH pin functionality), confirming its role in cost-optimized, temperature-monitored-by-system designs. Isolation is rated at 1900 V_RMS/1 min, supporting industrial-grade appliance safety requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	250 V - Maximum blocking voltage per MOSFET; enables direct interface with 200 V DC bus inputs.
R_DS(on) (max, 25°C)	1.0 Ω - Low conduction loss per FET; supports 3.0 A continuous output without forced cooling.
I_O @ T_C=25°C	3.0 A - Sustained per-phase DC current rating; defines thermal design margin for fan/pump motor windings.
V_IN Logic Compatibility	3.3 V - Direct interface with microcontroller GPIOs; eliminates level-shifting in MCU-based motor control.
Isolation Voltage	1900 V_RMS/1 min - Reinforced insulation barrier between power and logic domains; meets IEC 60730 Class B.
Deadtime (internal)	400 ns - Fixed non-overlap interval between high/low side drive signals; prevents shoot-through in 3-phase inverter leg.
T_J Operating Range	−40 to +150 °C - Junction temperature range enabling operation in sealed, thermally constrained appliance enclosures.

Pinout & Package

IRSM515-044DA2 uses a 23-pin DIP23A through-hole package with creepage-optimized spacing for 250V isolation. The body is thermally enhanced for PCB-mount heat dissipation via case-to-board conduction.

Pin/Terminal	Circuit Role	Design Meaning
1 COM	Logic ground reference	Common return for all low-side drivers and input logic; must be isolated from power ground at system level.
2 VB1–VB3 (pins 2,7,12)	High-side floating supply	Provides gate drive bias for upper FETs; referenced to respective VSx nodes; requires external bootstrap capacitors.
3,8,13 VCC1–VCC3	Low-side & logic supply	15 V ±1.5 V supply for driver ICs and level-shifting; decoupling critical for noise immunity.
4,9,14 HIN1–HIN3	High-side PWM input	3.3 V–compatible digital input controlling upper FETs; filtered (200–300 ns) to reject EMI.
5,10,15 LIN1–LIN3	Low-side PWM input	Complementary logic input for lower FETs; synchronized with HIN for precise deadtime control.
11 VTH	Thermistor output	No connection (NC) - confirms absence of integrated NTC; temperature monitoring must be implemented externally.
17 V+	DC bus positive input	Main high-voltage input node; connects to bulk capacitor; rated for 200 V DC operating voltage.
18,21,23 U/VS1, V/VS2, W/VS3	Phase outputs & floating supplies	Three-phase AC outputs with integrated high-side floating supply offsets; enable single-supply bootstrap topology.
19,20,22 VR1–VR3	Low-side source terminals	Open-source configuration allows shunt resistor placement on low-side legs for current sensing.

Key Features

Feature	Design Value
Integrated bootstrap diodes & resistors	R_BR = 250 Ω ensures stable high-side gate charging across temperature; eliminates external bootstrap components.
Matched propagation delay	≤1.5 µs variation across all six channels guarantees symmetrical PWM timing - essential for low-torque-ripple motor control.
−V_S transient tolerance	Driver survives negative transients down to −V_S, preventing false triggering during fast dV/dt commutation events.
Optimized dV/dt characteristics	Controlled slew rate balances switching loss (E_ON = 11 µJ @ 25°C) and EMI emission - validated for Class B appliance compliance.
Open-source current sensing	VR1–VR3 pins expose low-side FET sources, enabling accurate shunt-based phase current measurement without Hall sensors.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRSM505-044DA2	Includes integrated NTC thermistor (VTH pin active); otherwise identical electrical specs and pinout.	Required where on-module temperature monitoring is mandatory for thermal protection or efficiency optimization.	Select IRSM505-044DA2 only if real-time die temperature feedback is needed; otherwise IRSM515-044DA2 reduces system cost and complexity.
FAN7382MX	Standalone 3-channel gate driver IC (no integrated FETs); requires external 250V MOSFETs and bootstrap network.	Used when higher current (>3 A), custom thermal management, or discrete failure analysis is required.	Choose FAN7382MX only when modular scalability or failure-mode isolation outweighs BOM reduction benefits of integrated IPM.

Compared with IRSM505-044DA2, this part removes NTC sensing but retains identical drive performance and isolation; versus FAN7382MX, it trades design flexibility for integration density and reduced layout risk in space-constrained appliance PCBs.

FAQ

What is the maximum DC bus voltage supported by IRSM515-044DA2?

The IRSM515-044DA2 supports a recommended operating DC bus voltage up to 200 V, with absolute maximum blocking voltage rated at 250 V per MOSFET. Operation beyond 200 V is not advised due to increased switching stress and reduced safety margin against transients.

Does IRSM515-044DA2 require external bootstrap capacitors?

Yes - although internal bootstrap diodes and 250 Ω equivalent resistors are integrated, external ceramic bootstrap capacitors (typically 0.22–0.47 µF, X7R, 25 V) must be placed close to VB/VCC pins for reliable high-side gate drive under PWM duty cycles above 90%.

Can IRSM515-044DA2 be used with 5 V logic controllers?

No - the device is strictly 3.3 V logic compatible; applying 5 V to HIN/LIN inputs exceeds the absolute maximum VIN of VCC+0.3 V (≤16.8 V), risking permanent damage to input circuitry. A level-shifter or 3.3 V MCU is mandatory.

How is current sensing implemented with IRSM515-044DA2?

Current sensing is implemented via open-source configuration: VR1, VR2, and VR3 pins expose the source terminals of the three low-side MOSFETs. Shunt resistors placed between these pins and COM enable phase-current measurement with standard op-amp circuits, supporting both analog and ADC-based feedback.
