Product details
Overview
IMC099TT038XUMA1 from Infineon Technologies is a single-motor, non-scriptable, Class B–excluded iMOTION™ motor control IC implementing Field-Oriented Control (FOC) for PMSM drives, featuring integrated 3-phase gate drivers (6x PWM outputs), single-leg shunt current sensing, and sensorless or Hall-based position estimation. It operates with 3.3–5.0 V supply, supports UART and analog speed inputs, and targets cost-optimized industrial and appliance motor systems.
For engineers reviewing the IMC099TT038XUMA1 datasheet, IMC099TT038XUMA1 pinout, IMC099TT038XUMA1 application, or IMC099TT038XUMA1 equivalent, key selection criteria include its TSSOP-38 package, absence of scripting engine and IEC/UL 60730-1 Class B safety certification, fixed MCE firmware, and dedicated 6-channel PWM output architecture for 3-phase inverter control.
Technical Context
The IMC099TT038XUMA1 integrates a hardwired Motion Control Engine (MCE) executing real-time FOC algorithms at up to 96 MHz, with dedicated hardware blocks for angle estimation, space vector PWM generation, and fault handling. Its analog front-end includes three programmable-gain amplifiers for shunt-based current sensing and four analog comparators for overcurrent protection.
It features dual oscillators (96 MHz main, 32 kHz auxiliary), on-chip temperature sensing, voltage supervision, and configurable digital I/Os routed through a pin multiplexer controlled by the MCE. Unlike IMC101T, it excludes script engine execution and Class B safety firmware, resulting in reduced memory footprint and deterministic timing behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Control Algorithm | Fixed-field-oriented control (FOC) for PMSM with sensorless or Hall-based rotor position estimation |
| PWM Outputs | 6-channel complementary PWM (UH/UL, VH/VL, WH/WL) supporting space vector modulation |
| Current Sensing | Single-leg or phase-leg shunt interface with programmable gain amplifiers and 12-bit ADC |
| Supply Voltage Range | 3.3 V to 5.0 V - powers internal regulators and logic; requires external decoupling per pin |
| Operating Temperature | −40 °C to +125 °C ambient - qualified per JEDEC JESD22-A108 for industrial applications |
| Package | TSSOP-38 (PG-TSSOP-38-9) - surface-mount, 0.5 mm pitch, thermal pad not present |
| Safety Certification | No IEC/UL 60730-1 Class B compliance - intended for non-safety-critical variable-speed drive applications |
Pinout & Package
TSSOP-38 package (PG-TSSOP-38-9) with 0.5 mm lead pitch, exposed pad absent, and standard JEDEC MO-153 compliance. Pin functions are statically assigned per MCE firmware version; no runtime reconfiguration of core motor control pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 10, 26) | Power supply input | Dual 3.3–5.0 V supply pins requiring local 100 nF ceramic decoupling each |
| VSS (Pins 9, 25) | Ground reference | Dedicated ground return paths for analog and digital domains; must be low-impedance |
| PWMUH (Pin 12) | High-side gate driver output | Drives upper MOSFET/IGBT in phase U leg; 0.5 A peak sink/source capability |
| PWMUL (Pin 11) | Low-side gate driver output | Drives lower MOSFET/IGBT in phase U leg; complements PWMUH with dead-time insertion |
| PWMVH (Pin 14) | High-side gate driver output | Drives upper switch in phase V; synchronized with PWMUH/WPH for 3-phase commutation |
| PWMVL (Pin 13) | Low-side gate driver output | Drives lower switch in phase V; internally coordinated with PWMVH for shoot-through prevention |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Motion Control Engine (MCE) | Hardware-accelerated FOC execution with <1 µs loop latency; eliminates need for external MCU |
| 3-Phase Gate Driver Interface | 6 dedicated PWM outputs with programmable dead time and fault blanking - directly drives external half-bridge drivers |
| Shunt-Based Current Sensing | Supports single-shunt topology with on-chip PGA and 12-bit ADC - reduces BOM count vs. three-shunt solutions |
| Sensorless Rotor Position Estimation | Back-EMF observer with startup alignment - enables brushless operation without Hall sensors or encoders |
| UART Motor Control Interface | Asynchronous serial interface (up to 115.2 kbps) for speed command, status reporting, and diagnostics |
Applications
| Refrigerator Compressor Drive | Fan Speed Control Module |
|---|---|
|
Use Scenario: Variable-speed compressor in inverter refrigeration systems requiring energy-efficient, low-noise operation across wide load ranges. IC Role / Device Role / Timing Role: Primary motor controller executing FOC to regulate PMSM speed and torque in real time using single-shunt current feedback. Use Value: Enables >30% energy reduction vs. fixed-speed compressors while maintaining precise temperature stability via closed-loop speed regulation. |
Use Scenario: High-efficiency axial/centrifugal fan in HVAC units where acoustic noise and power consumption are critical. IC Role / Device Role / Timing Role: Standalone motor controller accepting analog voltage or UART commands to adjust fan RPM dynamically based on thermal demand. Use Value: Delivers smooth sinusoidal PWM output and sensorless startup - eliminating Hall sensors and reducing system cost by $0.85/unit. |
| Washing Machine Drum Motor | Small Industrial Pump Drive |
|
Use Scenario: Direct-drive drum motor in front-load washers needing high-torque startup, bidirectional rotation, and vibration suppression. IC Role / Device Role / Timing Role: Core motion controller performing field-weakening and torque ripple minimization during spin cycles using integrated angle estimator. Use Value: Achieves <±0.5% speed regulation accuracy under load transients - critical for balancing and spin-dry performance. |
Use Scenario: Compact 100–500 W pump in water treatment or irrigation systems operating in harsh ambient conditions. IC Role / Device Role / Timing Role: Self-contained motor controller with built-in overtemperature and overcurrent protection - enabling robust operation without external supervision. Use Value: Reduces design cycle by 8 weeks vs. custom MCU-based solution due to pre-validated MCE firmware and application schematics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PMSM motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IMC101T-T038 | Includes script engine and Class B safety firmware; larger Flash/RAM allocation | Required for applications needing user-defined logic (e.g., custom fault responses or multi-mode operation) | Select when application demands runtime customization beyond fixed MCE capabilities |
| IMC102T-F048 | LQFP-48 package with integrated boost/totem-pole PFC controller; higher pin count and voltage rating | Targeted at systems requiring active power factor correction alongside motor control | Choose only if PFC functionality is mandatory and board layout accommodates LQFP-48 footprint |
Compared with IMC101T-T038 and IMC102T-F048, the IMC099TT038XUMA1 offers lowest BOM cost and smallest PCB area for single-motor FOC applications without scripting or PFC - ideal for high-volume, cost-sensitive appliance designs.

FAQ
Does IMC099TT038XUMA1 support encoder-based position feedback?
No. The IMC099TT038XUMA1 supports only sensorless (back-EMF observer) and analog/digital Hall sensor interfaces for rotor position estimation. It lacks quadrature encoder interface circuitry, resolver excitation, or SINC filter blocks required for incremental or absolute encoders.
Can the PWM frequency be adjusted externally?
Yes. PWM carrier frequency is configured via MCE parameter tables loaded during initialization; typical range is 8–20 kHz. Frequency cannot be dynamically changed via analog or digital input pins - only through UART command or flash-reprogrammed parameters.
Is external bootstrap circuitry required for high-side gate driving?
Yes. The IMC099TT038XUMA1 provides only logic-level PWM outputs (PWMUH, PWMVH, PWMWH); external high-side gate driver ICs or discrete bootstrap networks are required to generate floating gate voltages for N-channel MOSFETs in the inverter stage.
What is the maximum motor power this IC can control?
IMC099TT038XUMA1 itself does not drive motors directly. When paired with 600 V, 30 A IGBTs or 650 V, 20 A SiC MOSFETs and appropriate gate drivers, it supports motor power levels up to 1.5 kW in continuous operation with adequate heatsinking and current sensing.
