Product details

Overview

IMI111T026HXUMA1 from Infineon Technologies is a fully integrated iMOTION™ intelligent power module (IPM) for PMSM/BLDC motor control, combining Motion Control Engine (MCE), 600 V/2 A TRENCHSTOP™ IGBTs, high-voltage gate driver, and analog sensing in a single DSO-22 package. It delivers sensorless field-oriented control (FOC), single-shunt current sensing, UART/analog speed interface, and IEC/UL 60730-1 Class B safety certification - enabling compact, heatsink-free fan and pump drives up to 50 W.

For engineers reviewing the IMI111T026HXUMA1 datasheet, IMI111T026HXUMA1 pinout, IMI111T026HXUMA1 application, or IMI111T026HXUMA1 equivalent, this IPM provides turnkey motor control with script-customizable logic, integrated over-current protection via analog comparators, built-in temperature sensing, and flexible 3.3 V/5.0 V controller supply compatibility - critical for rapid deployment in cost-sensitive, space-constrained variable-speed drive designs.

Technical Context

The IMI111T026HXUMA1 integrates a dedicated Motion Control Engine (MCE) that executes FOC algorithms without host MCU intervention, using internal 12-bit ADC, PWM generator with dead-time insertion, and synchronous current sampling. Its gate driver features 600 V blocking voltage, 15 V supply, integrated bootstrap diodes, and shoot-through prevention logic.

It supports sensorless operation via back-EMF estimation, accepts analog speed commands (0–5 V) or UART-based control, and implements hardware-level protections including over-current (via ISS input + IREF DAC reference), over-temperature (internal sensor), and under-voltage lockout on VDD and VCC rails - all validated per JEDEC47/20/22 for industrial reliability.

Pinout & Package

The IMI111T026HXUMA1 uses the PG-DSO-22-1 package: 22-pin, surface-mount, thermally enhanced, with isolated high-voltage and low-voltage sections. Creepage distance ≥2.2 mm between HV pads ensures robust insulation in 600 V systems.

12 (UN)	Power output	U-phase low-side IGBT collector - must be connected to UP (U-phase high-side emitter) on PCB.
13 (VN)	Power output	V-phase low-side IGBT collector - must be connected to VP (V-phase high-side emitter) on PCB.
14 (W/VSW)	Power output	W-phase low-side IGBT collector or switch node - used for W-phase output or auxiliary switching function.

Key Features

Feature	Design Value
Turnkey FOC Execution	MCE runs complete sensorless field-oriented control loop internally - eliminates need for host MCU computation and reduces system latency.
Script-Based Customization	Integrated script engine allows runtime modification of speed ramps, fault responses, and UI logic without altering core MCE firmware.
Hardware Fault Protection	Analog comparators monitor ISS and VDC in real time, triggering immediate shutdown on over-current or over-voltage - independent of software execution.

Thermal Robustness	Built-in temperature sensor feeds real-time die temperature to MCE for derating and thermal shutdown - no external sensor required.

Applications

Small Appliance Fans

Condenser Pumps

Use Scenario: Variable-speed cooling fan in refrigerators or HVAC units requiring quiet, energy-efficient airflow modulation.

IC Role / Device Role / Timing Role: Primary motor controller executing sensorless FOC at 16 kHz PWM, managing speed via analog voltage or UART commands.

Use Scenario: Low-power condensate removal pump in dehumidifiers or air conditioners operating intermittently under varying load.

IC Role / Device Role / Timing Role: Integrated IPM providing closed-loop speed regulation, over-current shutdown, and thermal foldback during stall conditions.

Use Value: Eliminates need for external current sense amplifiers and discrete protection ICs, cutting bill-of-materials cost by ~30%.

Smart Home Compressors

Industrial Blowers

Use Scenario: Miniature hermetic compressor in portable AC units or smart wine coolers requiring precise torque control and soft-start.

IC Role / Device Role / Timing Role: MCE-managed FOC with adaptive flux weakening and dynamic current limiting during startup transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar motor control IPM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FAN9612MPX	Standalone 600 V 3-phase gate driver (no embedded MCE or IGBTs); requires external MCU and discrete IGBTs.	Lacks turnkey FOC - suitable only where full custom control algorithm implementation is needed.	Select when design requires non-standard commutation schemes or multi-motor coordination beyond MCE capabilities.
FSB50450	600 V/4 A IPM with integrated driver but no motion control engine; relies on external MCU for FOC execution.	Higher current rating but adds complexity: needs external ADC, PWM timing, and protection logic implementation.	Choose for higher-power pumps (>70 W) where thermal margin justifies added firmware development and component count.

Compared with FAN9612MPX and FSB50450, the IMI111T026HXUMA1 uniquely delivers certified, self-contained FOC execution - reducing time-to-market by eliminating MCU firmware development, analog signal conditioning, and safety certification effort for Class B motor drives.

FAQ

What motor types does the IMI111T026HXUMA1 support?

The IMI111T026HXUMA1 is optimized for permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors. It executes field-oriented control (FOC) with sensorless operation using back-EMF estimation, and supports both trapezoidal and sinusoidal commutation via its integrated Motion Control Engine. It is not designed for induction or stepper motors.

Does the IMI111T026HXUMA1 require an external microcontroller?

No - the IMI111T026HXUMA1 contains a self-contained Motion Control Engine (MCE) that runs FOC algorithms autonomously. An external MCU is optional and only needed for high-level system coordination (e.g., user interface, network communication). All real-time motor control, protection, and PWM generation occur internally.

How is over-current protection implemented?

Over-current protection uses a dedicated analog comparator that continuously monitors the ISS pin against the IREF DAC output voltage. When ISS exceeds IREF, the comparator triggers immediate gate shutdown within 200 ns - independent of MCE software execution - ensuring robust short-circuit protection without firmware dependency.

Can the IMI111T026HXUMA1 operate without a heatsink?

Yes - in typical fan applications using 16 kHz PWM and 2-phase switching, the IMI111T026HXUMA1 delivers up to 50 W output without an external heatsink, provided the PCB thermal design meets R_th(C–A) ≤ specified value and ΔT_CA ≤ 60°C. Thermal performance is validated per JEDEC22-A104 and JEDEC22-A108 standards.
