Infineon Technologies IRSM836-015MATR

Overview

IRSM836-015MATR from Infineon Technologies (formerly International Rectifier) is a 1A, 500V 3-phase integrated power module (IPM) with integrated gate drivers, bootstrap diodes, and protection circuitry for brushless DC motor control in compact appliances. It delivers 40W motor drive capability without heatsink, features 3.3V Schmitt-trigger logic inputs, matched 1.0–1.5µs propagation delay across all six channels, and operates with 400V DC bus input.

For engineers reviewing the IRSM836-015MATR datasheet, IRSM836-015MATR pinout, IRSM836-015MATR application, or IRSM836-015MATR equivalent, key selection criteria include isolated 1500VRMS package rating, open-source shunt sensing support, under-voltage lockout on both VCC and VB supplies, and ITRIP-based overcurrent protection with 100–330ns blanking time.

Technical Context

This IPM integrates three high-side and three low-side Trench FREDFETs with a monolithic 3-phase high-voltage IC driver. Its architecture enables direct 3.3V logic interfacing while maintaining ±20V offset tolerance on VS pins and supporting up to 20kHz PWM carrier frequency.

The module implements cross-conduction prevention logic, dV/dt-optimized switching for EMI/loss trade-off, and fault reporting via open-drain FLT pin. Protection functions include UVLO on all channels, thermal shutdown, and ITRIP-triggered shutdown with 590–950ns fault response latency.

Key Specifications

Pinout & Package

IRSM836-015MATR uses a 36-lead PQFN package (12 × 12 mm, 1.0 mm height) with exposed thermal pad on bottom side for PCB-level heat dissipation. The package provides internal galvanic isolation between high-voltage power stage and low-voltage logic interface.

FAQ

What is the maximum DC bus voltage supported by IRSM836-015MATR?

The device supports up to 400V DC bus input per recommended operating conditions. Its 500V blocking voltage provides 25% margin for transient overvoltage events. Operation above 400V violates recommended conditions and risks premature failure due to increased avalanche stress and reduced noise immunity.

Does IRSM836-015MATR require an external heatsink?

No. The module functions without a heatsink up to 40W motor power output, enabled by its 3.8°C/W junction-to-case thermal resistance and PQFN package's exposed thermal pad. PCB copper area ≥4 cm² under the thermal pad is required to maintain TJ ≤150°C at full 1A load.

How does the ITRIP overcurrent protection function?

ITRIP monitors shunt resistor voltage with a 0.37–0.55V threshold and 60mV hysteresis. Upon exceeding threshold, a 100–330ns blanking window prevents false triggering from switching noise, followed by 590–950ns propagation to FLT pin assertion and gate shutdown. The function operates independently per phase.

Can IRSM836-015MATR be used with 5V logic microcontrollers?

No. Its HIN/LIN/EN inputs are specified for 3.3V Schmitt-trigger logic only. Applying 5V exceeds the absolute maximum VIN of VCC+0.3V (≤18.8V) but violates recommended 0–5V range and risks latch-up due to internal clamp diode conduction. A level shifter or 3.3V MCU is required.
