Motor Driver Provides Complete Solution for Industrial Designs

Infineon Technologies has launched the IFX007T NovalithIC motor driver for industrial applications. The IFX007T smart half-bridge provides an easy and efficient way to drive brushed and brushless motors, integrating a p-channel high-side MOSFET, an n-channel low-side MOSFET and a driver IC into one package. Along with a microcontroller and power supply, no other devices are necessary to drive a motor.

For many years, Infineon has followed this NovalithIC integrated approach for automotive applications. According to Infineon, the IFX007T now allows industrial system designers to benefit from this experience. It is qualified according to JESD47I and can be used to drive motors with supplies up to 40 V and peak currents up to 55 A. The broad application range includes pumps, healthcare, home and garden appliances as well as industrial automation, fans and many more.

Ease-of-use is a key benefit of the integrated solution. System designers save layout and manufacturing effort while reducing stray inductances and external components. Additionally, only three general purpose microcontroller pins are needed to control a full H-bridge.

The IFX007T has integrated self-protection, including over-temperature and cross-current protection. Within an H-bridge configuration, the half-bridge approach provides logic redundancy—if one device fails, the other can still stop the motor.

Another key benefit is the flexible motor control. The IFX007T can be used in either half-bridge, H-bridge or three-phase configurations. Furthermore, the motor speed can be adjusted via pulse width modulation (PWM) up to 25 kHz. Active freewheeling is possible from either the high side or the low side. An adjustable slew rate enables reduction of electromagnetic emissions.

Eval Board for Half-Bridge SiC Power Modules

Analog Devices, in collaboration with Microsemi, has introduced a high power evaluation board for half-bridge SiC power modules with up to 1,200 V and 50 A at 200 kHz switching frequency. The isolated board is engineered to improve design reliability while also reducing the need to create additional prototypes—saving time, lowering costs, and decreasing time to market for power conversion and energy storage system designers.

The board can be used as the building block of more complex topologies, such as full-bridge or multi-level converters, for complete bench debugging of customer solutions. It can also function as a final evaluation platform or in converter-like configuration for full test and evaluation of Analog Devices’ ADuM4135 isolated gate driver with iCoupler digital isolation technology and LT3999 DC-DC driver in a high-power system.

The high-power evaluation board enables Microsemi’s SiC power modules to provide benefits such as a common test bench, higher power density for reduced size and cost, and isolated and conductive substrate and minimum parasitic capacitance for higher efficiency, performance, and excellent thermal management. These attributes make the board suitable for applications including electric vehicle (EV) charging, hybrid EV (HEV)/EV onboard charging, DC-DC converters, switched mode power supply, high-power motor control and aviation actuation systems, plasma/semi cap equipment, lasers and welding, MRIs and X-rays. The EV-MS4135PL1Z-UI Evaluation Board is priced at $495.
