Infineon Technologies IRSM836-084MATR

Overview

IRSM836-084MATR from Infineon Technologies (formerly International Rectifier) is a 7A, 250V 3-phase integrated power module (IPM) for brushless AC motor drives in compact appliances. It integrates six Trench MOSFETs, high-voltage gate drivers, bootstrap diodes/resistors, UVLO, overcurrent protection, and fault reporting in a single 12×12 mm PQFN package-enabling fan and pump motor control up to ~150W without heatsink.

For engineers reviewing the IRSM836-084MATR datasheet, IRSM836-084MATR pinout, IRSM836-084MATR application, or IRSM836-084MATR equivalent, key selection criteria include its 250V blocking voltage, matched 0.7–1.5 µs propagation delay across all channels, 1500 VRMS isolation, 3.3V Schmitt-triggered logic inputs, and integrated open-source shunt sensing for current monitoring.

Technical Context

This IPM implements a fully integrated 3-phase inverter stage with independent high-side (HIN1–3) and low-side (LIN1–3) gate drivers, each referenced to floating VSx supplies. The internal HVIC architecture supports dV/dt-optimized switching and cross-conduction prevention logic to ensure shoot-through immunity during PWM commutation.

It features a dedicated ITRIP input with 0.46 V typical threshold and 100–330 ns blanking time, enabling fast overcurrent shutdown (<1 µs fault response), while EN pin provides global disable with 700–1000 ns turn-off propagation. Fault status is reported via open-drain FLT output with 50–100 Ω pull-down resistance.

FAQ

Does IRSM836-084MATR require an external heatsink?

No. With a junction-to-case-bottom thermal resistance of 2.9 °C/W and optimized MOSFET RDS(on) of 0.31–0.45 Ω, the device dissipates heat efficiently through its exposed thermal pad into PCB copper pours. It delivers full 7 A continuous output at 25°C ambient without external heatsink-validated for ~150 W motor loads in fan and pump applications.

What is the function of the RCIN pin?

RCIN is an active-high reset control input that clears the internal fault latch after a shutdown event (e.g., overcurrent or UVLO). When driven high, it releases the FLT pin from low state, allowing normal operation to resume once the fault condition is removed-enabling automatic recovery without MCU intervention.

Can IRSM836-084MATR drive a sensorless BLDC motor?

Yes. Its six-channel gate drive, matched propagation delays (≤0.8 µs variation), and integrated ITRIP-based current sensing support sensorless commutation algorithms. Combined with external MCU-based back-EMF detection and timing control, it forms a complete, compact inverter stage for fan and pump applications.

How is isolation implemented in this IPM?

Isolation is achieved via internal reinforced insulation between the high-voltage power section (U/V/W, V+, VBx) and low-voltage logic section (HIN/LIN/ITRIP/FLT). Rated at 1500 VRMS for 1 minute per IEC 60730, it uses proprietary dielectric barriers and package molding-verified by Infineon's industrial qualification (JEDEC JESD47E) and MSL3 moisture sensitivity rating.
