Overview
The IRMCF171TR is a sensorless motor driver integrating power MOSFETs, designed for AC, DC, induction, and synchronous motors. It operates on a 3V to 3.6V supply voltage within a -40°C to 85°C temperature range. The component utilizes a 48-LQFP (7x7) surface-mount package. Key interfaces include I2C, RS-232, and SPI. It features three half-bridge pre-drivers and functions as a controller for commutation and direction management.
Feature Summary
- Integrates power MOSFETs with control logic for sensorless operation
- Supports multiple motor types including AC, DC, induction, and synchronous
- Provides flexible communication via I2C, RS-232, and SPI interfaces
- Includes dedicated pre-drivers for three half-bridge configurations
Applications
- Home appliances
- Fan controllers
- Motor motion control systems
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging versus TY for tray. Confirm end-of-life status and discontinuation notifications prior to design finalization. Ensure compatibility with the required 3V to 3.6V supply rails and interface protocols. Check moisture sensitivity level requirements for storage and reflow processes.
Selection Notes
Select this component when a single-chip solution combining power stages and microcontroller functionality is required. It is suitable for applications needing sensorless control of various motor types. Consider the 48-pin LQFP footprint constraints and the specific voltage range limitations compared to higher voltage alternatives.
Part Context
This part belongs to the iMOTION and MCE series from Infineon Technologies. It represents an integrated approach to motor control by combining digital control with power switching elements. The family targets cost-sensitive applications requiring reliable performance in compact form factors.
Replacement Considerations
The IRMCF171TY serves as a direct alternative differing primarily in packaging type (tray versus tape and reel). Verify pinout and functional equivalence before substitution.
