The suite streamlines development and testing, providing real-time parameter monitoring for valuable insights into motor performance, efficiency, and reliability. This enables engineers to quickly identify issues, optimize designs, and enhance overall functionality. It offers effortless and accurate board setup, comprehensive signal analysis, and customized status monitoring. ModusToolbox Motor Suite features automatic detection and recognition of supported boards and kits, real-time visualization, and monitoring of motor control related signals. It also provides optimized system performance with pre-configured algorithms and real-time monitoring of critical system parameters. Additionally, the solution offers sophisticated algorithms that ensure control robustness across many motor types and applications. It currently includes out-of-the-box support for Infineon’s XMC7000 microcontrollers and will further expand its capability to include industrial MCUs, with PSOC Control integration confirmed for upcoming releases.

In addition to its comprehensive feature set, the ModusToolbox Motor Suite is designed to be highly versatile and easy to use. It provides a seamless graphical user interface for motor control development and an easily adaptable, hardware-abstracted motor control core library.

Infineon will showcase a demo featuring the ModusToolbox Motor Suite at electronica 2024 in Munich from 12 to 15 November (Hall C3, Booth 502).

Power Integrations

BridgeSwitch-2 ICs handle operational exceptions in hardware, which permits the use of IEC 60730 Class A safety software, reducing certification time by months. Quiescent BLDC inverters can be ordered into sleep mode, reducing driver power consumption to less than 10 mW; this leaves more power available under regulated standby power limits to be allocated for loads such as network access and monitoring.

BridgeSwitch-2 ICs address a power range of 30 to 746 W (1 HP), encompassing a broad range of applications including heat exchanger fans, refrigerator compressors, fluid and circulation pumps, gas boiler combustion fans, washing machine drums and kitchen blenders and mixers. The IHB architecture reduces component count by 50 percent and PCB space by 30 percent over discrete designs by eliminating shunt resistors and associated signal conditioning circuits. Shunt losses are also eliminated, improving efficiency. Precise motor control is achieved with the built-in real-time reporting of phase current (IPH) information. Accurate turn-on/off gate drive and a soft-body diode result in a typical EMI profile 10 dB lower than existing drivers, so a smaller EMI filter can be selected.

BridgeSwitch-2 ICs feature built-in DC overvoltage protection and current limits that protect the inverter and the system without relying on system software. The choice of error-flag or comprehensive fault bus reporting supports a range of system requirements. Emerging use-cases like failure prediction are now possible with the high accuracy of the built-in IPH information and comprehensive reporting via the fault bus. BridgeSwitch-2 motor drives use built-in, hardware-based low- and high-side over-current protection to meet IEC 60335-1 Class A requirements. BridgeSwitch-2 also works without an auxiliary power supply, further reducing PCB area and component count.

Pricing for BridgeSwitch-2 ICs starts at $0.48 for 10,000-unit quantities. A 150 W reference design and design report, RDK-974 can be freely downloaded.

emUSB-C PD turns the cable into a smart connection, enabling the detection of the type of device connected, power supply capabilities, USB Host/Device software, and more.

Specifically, devices that have rechargeable batteries benefit from the extra power that can be delivered via USB-C cables, charging faster. Having the cable communicate its capabilities ensures that optimum power is delivered while staying within cable specifications.

SEGGER’s USB-C PD stack is designed to work on any embedded system with a USB-C PD controller.  Divided into two layers, emUSB-C features an upper device-independent USB-C PD protocol layer and a target-dependent device driver layer.  SEGGER can provide immediate delivery of a complete solution, top to bottom, with support for devices from ST’s STM32H5xx and STM32U5xx device families; other device drivers are in preparation.
