Microcontroller integrated circuits for SWaP-constrained motor control applications introduced by Infineon

Aug. 3, 2022
Motor controllers come in 9-by-9-millimeter 4-pin VQFN packaging, and are for size-, weight-, and power-consumption (SWaP)-constrained applications.

NEUBIBERG, Germany – Infineon Technologies AG in Neubiberg, Germany, is introducing MOTIX IMD700A and IMD701A programmable motor control devices for unmanned aerial vehicles (UAVs), automated guided vehicles, e-bikes, and cordless power tools.

The motor controllers come in 9-by-9-millimeter 4-pin VQFN packaging, and offer the integration and high power density necessary for size-, weight-, and power-consumption (SWaP)-constrained electronics applications.

In one package, the MOTIX IMD70xA controllers combine the MOTIX 6EDL7141 3-phase gate driver IC features with an additional XMC1404 microcontroller, whose peripherals and specifications are optimized for motor control and drives.

Infineon’s XMC1404 microcontroller includes a math coprocessor clocked at 96 MHz to enhance calculations commonly used in sensorless field-oriented control (FOC) algorithms enabling higher system performance. The XMC1404 a;sp inherits most of the high-end peripherals found in the XMC4000 family, including PWM timers, position interface (POSIF), and serial communication modules (including CAN).

The motor control IC features controllability of the gate drive slew rate to protect systems from electromagnetic interference (EMI). IMD70xA controllers support adjustable gate drive supply voltage even at low battery voltage levels thanks to built-in high- and low-side charge pumps, as well as many other adjustable gate driver parameters.

EMI management by the digital configuration of the gate drive helps designers optimize at the EMI test facility without the need to change components on the board. In addition, both products come with motor-drive-specific system protection features such as OCP, UVLO, over-temperature, and locked rotor detection.
