IRSM836-045MATR Equivalent & Substitute Parts

Part Overview

The IRSM836-045MATR is an integrated motor driver IC manufactured by Infineon Technologies, designed for AC and synchronous motor control applications in appliance systems. This fully integrated driver combines control and power stage functionality in a 37-PowerVQFN package with UMOS technology. The part is currently in active production status with 1900 units available in inventory. Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining functional compatibility in target applications.

Substitute Part Grouping Explanation

Substitution eligibility for the IRSM836-045MATR is determined by strict equivalence across the following critical parameters:

• Manufacturer: Infineon Technologies (same manufacturer ensures design compatibility)
• Function: Driver - Fully Integrated, Control and Power Stage (identical functional architecture)
• Motor Type: AC, Synchronous (same motor control application class)
• Output Configuration: Half Bridge (3) (identical output topology)
• Interface: Parallel (same control interface)
• Technology: UMOS (same semiconductor technology)
• Voltage Supply Range: 13.5V ~ 16.5V (identical supply voltage specification)
• Voltage Load (Max): 400V (identical maximum load voltage)
• Operating Temperature: -40°C ~ 150°C (identical thermal operating range)
• Mounting Type: Surface Mount (same PCB assembly method)
• RoHS Status: ROHS3 Compliant (same environmental compliance)
• MSL Rating: 3 (168 Hours) (same moisture sensitivity level)

Variations in output current rating and package pin count do not disqualify substitution when all other parameters remain equivalent, as these represent design flexibility within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the IRSM836-045MATR and IRSM836-035MATR are active production parts from Infineon Technologies with identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). Selection between these parts is based on output current requirements: the IRSM836-045MATR provides 4A output current, while the IRSM836-035MATR provides 3A output current. Circuit design specifications must confirm that the lower current rating of the substitute part meets application load requirements. Both parts maintain identical electrical and thermal operating specifications across supply voltage, load voltage, and temperature ranges. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect functional compatibility but may influence procurement and assembly logistics.

Frequently Asked Questions (FAQ)

Q: Can IRSM836-035MATR replace IRSM836-045MATR in existing designs?

A: Substitution is valid only when circuit load current requirements do not exceed 3A. The IRSM836-035MATR provides identical control functionality and electrical specifications across all parameters except output current rating. If the application requires sustained output current above 3A, the IRSM836-045MATR must be retained.

Q: What is the significance of the package designation change from 37-PowerVQFN to 36-PowerVQFN?

A: The package designation reflects pin count differences (37 pins versus 36 pins). PCB layout and footprint designs are specific to each package variant. Direct substitution on existing PCBs designed for the 37-pin package is not possible without layout modification.

Q: Are there differences in thermal performance between these parts?

A: Both parts operate across the identical temperature range (-40°C to 150°C junction temperature) and share the same MSL rating (3, 168 hours). Thermal performance differences, if any, are determined by the output current rating and resulting power dissipation in specific applications.

Q: Do both parts require identical control interface connections?

A: Yes. Both parts use parallel interface control architecture and are designed for AC and synchronous motor applications. Control signal compatibility is maintained across the product family.

Q: What packaging format considerations apply to procurement?

A: IRSM836-045MATR is supplied in Tape & Reel format, while IRSM836-035MATR is available in Cut Tape and Digi-Reel formats. Procurement and assembly processes may differ based on packaging format, but functional performance is not affected.
