Infineon Technologies IRSM506-076DA

Overview

IRSM506-076DA from Infineon Technologies is a 600V, 4A 3-phase Integrated Power Module (IPM) with integrated half-bridge gate drivers, Trench IGBTs, bootstrap circuitry, and NTC-based temperature feedback. It serves as a compact inverter stage for brushless DC motor control in small appliances, delivering 1.7V max V_CE(sat) at 1A/25°C and optimized dV/dt for low EMI in fan and pump drives.

For engineers reviewing the IRSM506-076DA datasheet, IRSM506-076DA pinout, IRSM506-076DA application, or IRSM506-076DA equivalent, key selection criteria include its DIP23A package, open-emitter topology for shunt current sensing, 3.3V logic compatibility, -40°C to 150°C operating range, and integrated thermal monitoring via VTH pin.

Technical Context

This IPM integrates three independent high-voltage IC (HVIC) half-bridge drivers with matched propagation delay (0.7–1.5 µs turn-on, 0.8–1.5 µs turn-off) and built-in shoot-through protection via advanced input filtering. Each channel features under-voltage lockout (10.2–11.8 V hysteresis) and tolerance to negative transient voltage on -Vs pins.

The module implements open-emitter outputs (pins 19–22) enabling single-shunt or leg-shunt current sensing, while its 1900 V_RMS isolation rating and rugged design target PM motor loads in industrial-grade small appliances requiring long-term reliability under thermal cycling.

Key Specifications

FAQ

What is the function of the VTH pin on IRSM506-076DA?

The VTH pin provides analog output from an integrated NTC thermistor (47 kΩ nominal at 25°C, B = 4050 K), enabling direct junction temperature monitoring. It connects to a microcontroller ADC input; voltage varies inversely with temperature, allowing real-time thermal derating or fault shutdown before reaching 125°C maximum rated value.

Can IRSM506-076DA operate with a 3.3 V MCU without level shifters?

Yes. Its HIN/LIN inputs have 2.2 V typical positive-going threshold and 0.8 V negative-going threshold, fully compatible with 3.3 V CMOS logic. No external level shifting is required, and the inputs include internal filtering to suppress noise-induced false triggering in electrically noisy motor environments.

How does the open-emitter configuration support current sensing?

Pins VR1, VR2, and VR3 are low-side emitter outputs, allowing a single shunt resistor to be placed between each VRx pin and COM. This enables either per-phase current measurement or summed current sensing. The configuration avoids high-side sensing complexity while maintaining galvanic isolation between power and logic grounds.

What isolation certification does IRSM506-076DA hold?

IRSM506-076DA is UL certified (File E252584) with 1900 V_RMS isolation for 1 minute, meeting reinforced insulation requirements for Class II appliances. It also complies with RoHS, achieves MSL3 per JEDEC J-STD-020, and passes Class B machine-model and Class 2 human-body ESD testing.
