Product details

Overview

IRSM505-084DA from Infineon Technologies (formerly International Rectifier) is a 250V, 3-phase integrated power module (IPM) with integrated high-voltage gate drivers, 0.45Ω max R_DS(on) trench MOSFETs, and on-die NTC thermistor for temperature feedback. It delivers 4.6A DC per phase at 25°C, supports 20kHz PWM carrier frequency, and is qualified for industrial motor drive applications in small appliances such as energy-efficient fans and pumps.

For engineers reviewing the IRSM505-084DA datasheet, IRSM505-084DA pinout, IRSM505-084DA application, or IRSM505-084DA equivalent, key selection criteria include its DIP23A package, 1900V_RMS isolation rating, matched propagation delay (<1.5µs), open-source current sensing capability, and integrated bootstrap functionality for simplified gate drive design.

Technical Context

This IPM integrates three half-bridge HVICs with independent high-side floating supplies (VB1–VB3), logic-compatible inputs (3.3V/5V-tolerant), and under-voltage lockout on all channels. Each channel features matched turn-on/turn-off propagation delays (0.7–1.5µs) and built-in deadtime (~400ns) to prevent shoot-through.

The module implements low-EMI optimization via controlled dV/dt, includes internal bootstrap resistors (250Ω), and provides isolated thermistor output (VTH) referenced to COM for real-time junction temperature monitoring - a feature exclusive to the IRSM505-084 variant.

FAQ

What is the function of the VTH pin on IRSM505-084DA?

The VTH pin provides analog output from an integrated NTC thermistor (47kΩ @25°C, B=4050K) embedded in the module die. It connects to an MCU ADC input to monitor real-time junction temperature, enabling dynamic thermal derating and overtemperature protection without external sensors or calibration.

Can IRSM505-084DA operate with a 3.3V microcontroller without level shifters?

Yes - its HIN and LIN inputs are fully 3.3V logic compatible with 0.8V/2.2V thresholds and tolerate up to VCC+0.3V. No level-shifting circuitry is required when interfacing with standard 3.3V MCUs, simplifying control interface design and reducing component count.

How does the open-source current sensing work on IRSM505-084DA?

VR1, VR2, and VR3 are dedicated low-side source terminals that expose the emitter/source nodes of each lower MOSFET. Connecting shunt resistors between these pins and COM enables direct, polarity-correct current measurement - eliminating need for inverted-sense amplifiers or complex differential configurations.

What is the significance of the 1900V_RMS isolation rating?

This rating certifies reinforced insulation between power and logic sections per UL 60747-19, ensuring safe operation in mains-connected appliances. It permits use in Class I equipment without additional isolation barriers, streamlining safety certification for products like fans, pumps, and compressors targeting IEC 60335-1 compliance.
