Infineon IMD700AQ064X128AAXUMA1

MOTIX IMD70xA is a controller specifically designed for 3 phase BLDC or PMSM drives applications. IMD70xA integrates a fully programmable XMC1404 ARM Cortex-M0 microcontroller from Infineon XMC1400 family with 6EDL7141, a 60V three phase smart gate driver with integrated power supply. Both devices integrated allow an ultra-compact design for drives applications up to 60V including not only the microcontroller and a flexible 3 phase gate driver, but also the complete power supply required in the system (synchronous buck converter and LDO), 3 current sense amplifiers, protections and a remarkable set of configurations to adjust to specific needs.

XMC1404, ARM Cortex-M0 based microcontroller, incorporates dedicated features to improve motor drives control. Features like the MATH Co-Processor, a hardware unit clocked at 96MHz, enhances the calculation of divisions and trigonometric functions like ‘Arctan’, commonly used in Field Oriented Control of PMSM. Additionally, XMC1404 inherits most of the high end peripherals found in XMC4000 family (ARM Cortex-M4), like PWM timers - CCU8 and CCU4 -, Position interface (POSIF) or serial communication modules including CAN, ensuring best in class control.

With up to 20 dedicated general purpose pins and up to 12 analog inputs, the user has full flexibility to implement specific functions externally like serial communications, security or safety related functions or auxiliary functions like LEDs, buttons or displays.

Internally, XMC1404 and 6EDL7141 are connected to ensure proper operation. These interconnects enable SPI communication between both devices for configurability and status reporting of 6EDL7141, 6 PWM signals for driving the motor, nFAULT reporting pin to inform the microcontroller of any possible fault on the power side, an enable driver pin, and a brake pin that can be also accessed externally for a double brake path.

6EDL7141 smart gate driver provides on the one side a flexible gate driving scheme and on the other side the necessary robustness and protection features to avoid failures in demanding drives systems. The gate driver outputs are placed strategically to allow best layout practices in power circuits.

In 6EDL7141, separate charge pumps for low and high side gate drivers support 100% duty cycle and low voltage supply operation. Supplies for the gate drivers are programmable to one of the following levels: 7V, 10V, 12V, 15V.
