Product details

Overview

IMD701AQ064X128AAXUMA1 from Infineon is a fully integrated 3-phase BLDC/PMSM motor controller combining an ARM® Cortex-M0 microcontroller (XMC1404, 48 MHz) with a smart gate driver (6EDL7141), synchronous buck converter, 5V/3.3V LDO (300 mA), and three current sense amplifiers. It operates from 5.5 V to 60 V, supports trapezoidal commutation and FOC, and targets compact, high-efficiency motor drives in battery-powered tools and e-bikes.

For engineers reviewing the IMD701AQ064X128AAXUMA1 datasheet, IMD701AQ064X128AAXUMA1 pinout, IMD701AQ064X128AAXUMA1 application, or IMD701AQ064X128AAXUMA1 equivalent, key selection criteria include integrated gate drive current (1.5 A sink/source), programmable gate voltage (7–15 V), 12-bit ADC with up to 12 analog inputs, CCU8/CCU4 PWM timers for 3-phase inverter control, and thermal robustness in VQFN-64 package.

Technical Context

The device integrates XMC1404 MCU and 6EDL7141 gate driver via internal SPI, six dedicated PWM outputs, nFAULT reporting, brake, and enable signals - enabling tight coordination between control logic and power stage. The MATH co-processor (96 MHz) accelerates division and trigonometric functions critical for real-time FOC execution.

Its power architecture includes a programmable-frequency synchronous buck converter feeding a 300 mA LDO, dual charge pumps for 100% duty-cycle gate driving at low input voltages, and three current sense amplifiers with configurable gain/offset for bi-directional low-side or R_DS(on) sensing - all routed to XMC1404's 12-bit ADC with 1.1 MS/s sampling rate.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase BLDC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	ARM Cortex-M0 @ 48 MHz, integrated gate driver (650 mA), no buck converter - requires external 5 V supply	Lacks integrated power supply and current sense amps; needs external op-amps and regulators	Preferred for cost-sensitive, lower-current (<10 A) applications where board space is less constrained
MP6532GQ-Z	3-phase gate driver only (no MCU); 1.2 A drive strength; requires external MCU and power management	No embedded processing - mandates separate microcontroller and power ICs for full drive solution	Chosen when design requires custom motor control IP or deterministic real-time OS with external RAM/Flash

Compared with STSPIN32F0B and MP6532GQ-Z, IMD701AQ064X128AAXUMA1 delivers highest integration density and fastest time-to-control-loop closure - reducing component count by ≥12 parts and eliminating inter-IC timing skew in FOC execution.

FAQ

What is the maximum continuous motor current supported by IMD701AQ064X128AAXUMA1?

The device itself does not define a fixed motor current limit; instead, it supports continuous phase currents up to ~25 A depending on external MOSFET selection, PCB layout, thermal design, and gate drive voltage setting (7–15 V). Its ±1.5 A gate drive strength and thermal package enable reliable operation with 20–30 mΩ R_DS(on) MOSFETs under forced-air cooling.

Does IMD701AQ064X128AAXUMA1 support Field-Oriented Control (FOC) out of the box?

Yes - the integrated XMC1404 MCU includes a 96 MHz MATH co-processor optimized for real-time division and trigonometric calculations (e.g., arctan, sin/cos), and its CCU8 timers provide hardware-accelerated PWM generation with precise dead-time control - both essential for efficient FOC implementation. Infineon provides validated FOC firmware libraries and motor control SDKs.

Can the internal buck converter be disabled to use an external 5 V supply?

Yes - the buck converter can be disabled via SPI configuration, allowing DVDD to be supplied externally. In this mode, the internal LDO remains active and can be configured for 3.3 V or 5 V output, powered by the external rail. This supports designs requiring ultra-low noise analog supplies or redundancy.

Is the IMD701AQ064X128AAXUMA1 qualified for automotive applications?

No - it is specified for industrial and consumer applications (–40 °C to +125 °C ambient), with AEC-Q100 qualification not claimed. While it meets many automotive-like robustness requirements (e.g., 90 V pin tolerance, -8 V negative transient immunity), formal automotive qualification requires additional stress testing and documentation not provided for this variant.
