Infineon Technologies IMD700AQ064X128AAXUMA1

Overview

IMD700AQ064X128AAXUMA1 from Infineon is a fully integrated BLDC/PMSM motor controller combining an ARM® Cortex-M0 microcontroller (XMC1404, 48 MHz) and a 60V three-phase smart gate driver (6EDL7141). It delivers 1.5A peak gate drive current per channel, supports trapezoidal commutation and FOC, operates from 5.5V to 60V, and integrates synchronous buck + LDO power supply, three current sense amplifiers, and 20 GPIOs. Used in e-bikes and robotic lawn mowers.

For engineers reviewing the IMD700AQ064X128AAXUMA1 datasheet, IMD700AQ064X128AAXUMA1 pinout, IMD700AQ064X128AAXUMA1 application, or IMD700AQ064X128AAXUMA1 equivalent, key selection considerations include gate driver voltage programmability (7/10/12/15 V), independent high/low-side slew rate control, 12-bit ADC with 1.1 MS/s sampling, CCU8 timers for 3-phase PWM, and thermal shutdown with OTW/OTS reporting.

Technical Context

The device implements a tightly coupled dual-die architecture: XMC1404 MCU and 6EDL7141 gate driver communicate via dedicated SPI and share six PWM outputs, nFAULT, ENABLE, and BRAKE signals. The MATH co-processor (96 MHz) accelerates division and trigonometric functions critical for real-time FOC execution.

Its power system includes a programmable-frequency synchronous buck converter feeding a 3.3V/5V LDO (300 mA), dual charge pumps enabling 100% duty cycle operation down to low input voltages, and three rail-to-rail current sense amplifiers with configurable gain/offset for bi-directional low-side or R_DS(on) sensing.

FAQ

What is the maximum continuous motor phase current supported by IMD700AQ064X128AAXUMA1?

The device itself does not switch motor current directly-it drives external MOSFETs. Its 1.5 A peak gate drive current supports MOSFETs rated for ≥30 A continuous phase current (e.g., IPB070N15N3 G) when properly heatsinked and operated within 5.5–60 V input range and ambient ≤85°C. Actual current capability depends on external FET selection, PCB layout, and thermal design.

Does IMD700AQ064X128AAXUMA1 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 operations required by FOC algorithms. Infineon provides validated FOC firmware libraries (MOTIX™ Motor Control SDK) and reference designs, though application-specific tuning and sensor interface configuration remain the designer's responsibility.

Can the current sense amplifiers be used for R_DS(on) sensing without external shunts?

Yes-internal routing connects phase node voltages to CSA/B/C inputs, enabling R_DS(on) sensing. This mode requires careful calibration due to MOSFET parameter variation and temperature drift. Gain and offset are programmable via SPI, and amplifier outputs feed directly into XMC1404's ADC channels for digital correction.

Is the nFAULT pin latched or auto-clearing after fault recovery?

The nFAULT pin is actively driven low during fault conditions and remains asserted until the fault condition is cleared *and* the MCU issues a specific SPI command (0x0E register write) to reset the fault latch. This ensures reliable fault capture and prevents spurious re-enabling before root cause analysis or safe restart sequence execution.
