MOTIX™ | Battery Supplied BLDC Motor Controller ICs
MOTIX™ 3-phase motor control gate driver IC for battery supplied BLDC motor controllers
Infineon's MOTIX™ 3-phase motor control gate driver IC enables the development of high-performance battery-operated products using BLDC or PMSM motors. Low voltage brushless DC motors offer increased efficiency and lower maintenance compared to brushed motors.
Ideal applications for these low voltage motor controllers include cordless power tools, gardening products, and automated guided vehicles. IMD700A/IMD701A are the latest fully programmable motor controllers integrating the XMC1404 microcontroller with the 6EDL7141 3-phase gate driver IC in one package. MOTIX™ 6EDL7141 is available as a stand-alone device that has over 50 programmable parameters using a built-in digital SPI interface. It is fully configurable to drive a wide range of MOSFETs to yield the best possible system performance.
The key features of our battery supplied BLDC motor controller ICs include:
- Integrated power supplies
- Adjustable slew rate
- Programmable gate driver parameters
- 3x current shunt amplifier
- Complete dedicated motor control protection suite
Designed for maximum flexibility and high performance, Infineon’s MOTIX™ low-voltage motor controller IMD700A/IMD701A and 3-phase gate driver 6EDL7141 have an operating supply voltage between 5.5 V to 60 V. This makes it the ideal solution for brushless DC motor power tools that require fast and efficient charging solutions. Additionally, cordless power tools with higher battery supply voltages such as cordless drills with 24 V brushless DC motors can be used for both space- and cost-optimized designs. Light electric vehicles such as e-bikes, e-scooters, and low-speed electric cars that use Infineon’s brushless DC motor controllers with 24 V, 36 V, or 48 V battery capabilities exhibit increased battery life, longer operating range, and reduced charging times.
The benefits of our product solutions include:
- Reduced external components and PCB area
- Optimized efficiency and EMI
- Maximum flexibility to use different inverter FET’s
- Highly accurate current sense while saving external components
- Higher dynamic range to increase signal resolution
- Improved reliability and fault detection
