Infineon IMD701AQ064X128AAXUMA1

The IMD70xA is a controller specifically designed for three-phase BLDC or PMSM drive applications. It integrates a fully programmable XMC1404 microcontroller from the Infineon XMC1400 family based on the ARM® Cortex®-M0 core, along with a 60V three-phase smart gate driver with integrated power supply. This integration enables an ultra-compact design for drive applications up to 60V, encompassing not only the microcontroller and flexible three-phase gate driver, but also the complete system power supply (synchronous buck converter and LDO), three current sense amplifiers, protection features, and a range of excellent configuration options to accommodate specific requirements. The ARM® Cortex®-M0-based XMC1404 microcontroller integrates dedicated functions to enhance motor drive control. For example, a math co-processor unit running at 96MHz clock enhances computation of division and trigonometric functions such as 'Arctan' commonly used in PMSM field-oriented control. In addition, the XMC1404 inherits most of the high-end peripherals from the XMC4000 family (ARM® Cortex®-M4), such as PWM timers (CCU8 and CCU4), position interfaces, and serial communication modules including CAN, ensuring superior control performance. With up to 20 dedicated general-purpose pins and up to 12 analog inputs, users have the flexibility to implement external application-specific functions such as serial communication, safety-related functions, or auxiliary functions for LEDs, buttons, displays, and more. Internally, the XMC1404 and 6EDL7141 are interconnected to ensure proper operation. These interconnections provide SPI communication between the two for 6EDL7141 configurability and status reporting; 6 PWM signals for motor driving; an nFAULT reporting pin to notify the microcontroller of any potential faults on the power side; a driver enable pin; and a dual brake path brake pin that is also externally accessible. The 6EDL7141 smart gate driver provides both a flexible gate drive scheme and the necessary robustness and protection features to prevent failures in demanding drive systems. The gate driver outputs are strategically laid out to support optimal routing practices for the power circuit. Within the 6EDL7141, independent charge pumps for the low-side and high-side gate drivers support 100% duty cycle and low supply voltage operation. The gate driver supply voltage is programmable to one of the following levels: 7V, 10V, 12V, or 15V. Furthermore, the slew rate of the drive signals can be programmed with fine granularity.
