Product details
Overview
IMI111T046HXUMA1 from Infineon Technologies is a fully integrated iMOTION™ Intelligent Power Module (IPM) for PMSM/BLDC motor control, combining Motion Control Engine (MCE), 600 V/4 A TRENCHSTOP™ IGBTs, high-voltage gate driver, and protection circuitry in a single DSO-22 package. It delivers sensorless field-oriented control (FOC), single-shunt current sensing, UART/analog speed interface, and certified Class B safety per IEC/UL 60730-1 - enabling compact, heatsink-free fan and pump drives up to 70 W.
For engineers reviewing the IMI111T046HXUMA1 datasheet, IMI111T046HXUMA1 pinout, IMI111T046HXUMA1 application, or IMI111T046HXUMA1 equivalent, this IPM provides turnkey motor control with script-customizable logic, integrated over-current comparators, bootstrapped high-side drive, and thermal monitoring - eliminating external MCU, gate drivers, and discrete protection components in variable-speed appliance drives.
Technical Context
The IMI111T046HXUMA1 integrates a dedicated Motion Control Engine (MCE) that executes FOC algorithms without host CPU intervention, using internal 12-bit ADC, PWM generator with dead-time insertion, and synchronous current sampling. Its gate driver features integrated bootstrap diodes, UVLO on VCC/VDD, and shoot-through prevention logic tied directly to MCE timing signals.
All six IGBTs are Reverse Conducting Drive 2 (RCD2) type with 600 V blocking voltage and optimized dv/dt for EMI/loss trade-off; the module supports 2-phase or 3-phase switching at up to 16 kHz PWM frequency and operates with 3.3 V or 5.0 V controller supply and 15 V gate driver supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Rating | 600 V / 4 A IGBTs - supports continuous motor loads up to 70 W at 16 kHz PWM without heatsink under validated PCB thermal design (Rth(C-A) ≤ spec limit). |
| Control Architecture | Motion Control Engine (MCE) - hardware-accelerated FOC execution with no external processor required; includes built-in script engine for application-level customization. |
| Current Sensing | Single-shunt topology with ISS analog input and internal comparator-based over-current protection - reduces BOM count and PCB area vs. three-shunt solutions. |
| Safety Certification | IEC/UL 60730-1 Class B compliance - enables use in safety-critical home appliance motor controls without additional system-level certification effort. |
| Isolation Rating | 1500 VRMS for 1 minute - ensures reinforced insulation between high-voltage power stage and low-voltage control domain in compact DSO-22 footprint. |
| Package | PG-DSO-22-1 surface-mount package with 2.2 mm creepage distance between HV pads - improves system robustness in humid or dusty environments. |
| Interface Options | UART (TX0/RX0) and analog speed reference (VSP) - allows direct connection to microcontrollers or potentiometers without level-shifting or signal conditioning. |
Pinout & Package
IMI111T046HXUMA1 uses the PG-DSO-22-1 package: 22-pin, surface-mount, thermally enhanced DSO format with exposed thermal pad; creepage distance ≥2.2 mm between high-voltage terminals; RoHS-compliant; rated for industrial temperature range (−40 °C to +125 °C junction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TX0/PGOUT/GPIO1/SDA) | Digital I/O / UART TX / Pulse output | Configurable as serial transmit, programmable pulse generator, or general-purpose digital I/O; supports I²C SDA when enabled. |
| 2 (RX0/DIR/GPIO6/SCL/IR0) | Digital I/O / UART RX / Direction input | Accepts speed command direction signal or IR remote input; dual-function with I²C SCL capability in script-configured mode. |
| 3 (VSP/IR2) | Analog speed reference input | 0–5 V analog input sets motor speed target; internally scaled by MCE for FOC loop reference - eliminates need for external DAC or ADC. |
| 4 (ISS) | Single-shunt current sense input | Connects to shunt resistor placed on DC-link low side; feeds internal 12-bit ADC and comparator for real-time phase current reconstruction and fault detection. |
| 5 (VDC) | DC bus voltage sensing input | Monitors DC-link voltage for over-voltage protection and flux-weakening control; scaled internally to match ADC full-scale range. |
| 6 (IREF) | Over-current reference DAC output | Provides programmable threshold voltage to analog comparators - enables dynamic OCP level adjustment via MCE or script engine. |
| 7 (VDD) | Digital controller supply | 3.3 V or 5.0 V supply for MCE, flash, RAM, and digital peripherals; requires local decoupling capacitor per datasheet layout guidelines. |
| 8 (VCC) | Low-side gate driver supply | 15 V supply for LS IGBT drivers; derived from external boost or isolated supply; monitored for UVLO protection. |
| 9 (VSS) | Control signal ground | Dedicated low-noise ground return for digital and analog control circuitry - must be separated from power ground at single-point star connection. |
| 10 (GLV) | V-phase low-side gate (NC) | No-connect terminal; internal gate of V-phase LS IGBT - not routed to package pin to reduce parasitic coupling and simplify layout. |
| 11 (COM) | 3-phase low-side common emitter | Return path for all three low-side IGBT emitters; connects to DC-link negative rail and shunt resistor; critical for current sensing accuracy. |
| 12 (UN) | U-phase low-side collector | PCB trace must connect UN to UP (U-phase high-side emitter) to complete U-leg; defines current path for U-phase motor winding. |
| 13 (VN) | V-phase low-side collector | PCB trace must connect VN to VP (V-phase high-side emitter); forms V-leg current path - layout symmetry essential for balanced thermal distribution. |
| 14 (W/VSW) | W-phase low-side collector / switch node | Functions as W-phase LS collector and switching node for W-leg; also used as feedback point for VSW monitoring in certain configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Motion Control Engine (MCE) | Hardware-based FOC execution with zero host CPU overhead - reduces firmware development time and eliminates real-time scheduling constraints in resource-constrained systems. |
| Script Engine Customization | User-defined logic (e.g., startup ramp, fault recovery, user interface) runs alongside MCE without modifying core motor control algorithm - enables rapid application differentiation. |
| Sensorless PMSM/BLDC Operation | Back-EMF observer and PLL-based position estimation eliminate Hall sensors or encoders - lowers BOM cost and improves reliability in fan/pump applications. |
| Built-in Analog Comparators | Dedicated over-current protection with <1 µs response time - triggers immediate shutdown before IGBT destruction, independent of MCE software latency. |
| Thermal Monitoring | On-die temperature sensor with ±3 °C accuracy - enables dynamic derating and thermal foldback to extend lifetime in sealed or high-ambient environments. |

FAQ
What is the maximum continuous output power achievable with IMI111T046HXUMA1 without a heatsink?
Under validated PCB thermal conditions (Rth(C-A) ≤ specified value and ΔTca = 60 °C), IMI111T046HXUMA1 delivers up to 70 W mechanical output power in typical fan applications using 16 kHz PWM and 2-phase switching - confirmed in Infineon's application note AN2022-05 and datasheet Section 1.3.1, Table 4.4.1.
Does IMI111T046HXUMA1 require an external microcontroller to operate?
No - the integrated Motion Control Engine (MCE) executes field-oriented control autonomously; only configuration (e.g., speed reference via VSP or UART) and optional script logic are needed. No external MCU is required for basic operation, though one may be used for system-level coordination or HMI.
How is over-current protection implemented in IMI111T046HXUMA1?
It uses dedicated on-chip analog comparators monitoring the ISS pin against the programmable IREF voltage; response time is <1 µs, triggering immediate gate shutdown independent of MCE software execution - detailed in datasheet Section 4.2.3 and Figure 3.3.1.
Can the IMI111T046HXUMA1 drive both PMSM and BLDC motors?
Yes - the MCE supports both sensorless PMSM FOC and trapezoidal BLDC commutation modes; motor type selection and parameter tuning are performed via Infineon's iMOTION™ Commissioning Tool (IMCT) and stored in on-chip flash memory.
