Insights
Navitas expands GaN technology to motor drives with integrated half-bridge ICs that deliver improved efficiency and smaller footprints versus silicon IGBTs.
Navitas' new GaNSense Motor Drive ICs represent a strategic expansion into the $2B+ motor drive semiconductor market. These ICs integrate two GaN power transistors in a half-bridge configuration with sophisticated control and protection circuitry, enabling designers to simplify motor drive circuits while improving performance.
The bidirectional lossless current sensing capability is particularly significant for motor applications. Unlike conventional designs requiring energy-wasting shunt resistors, these ICs can measure current flow in both directions between motor coil phases without additional components. This directly translates to the 4% efficiency improvement versus silicon IGBTs.
The 40% PCB footprint reduction results from both the smaller GaN dies and the high integration level eliminating numerous discrete components. Meanwhile, the 15% system cost reduction comes from eliminating external components and reducing heatsink requirements.
The autonomous freewheeling function represents sophisticated control integration by automatically activating when reverse current is detected, minimizing losses during motor commutation cycles. This intelligent power handling maximizes efficiency in real-world operation.
The initial 650V portfolio with three variants (NV6257, NV6287, NV6288) offers designers flexibility for different power levels while maintaining consistent integration benefits. The comprehensive protection features address reliability challenges that historically limited GaN adoption in industrial applications.
This product launch demonstrates Navitas' evolution from mobile/consumer power delivery into higher-power industrial applications, leveraging their GaN integration expertise to address more complex power control challenges.
Navitas' GaN motor drive ICs deliver measurable efficiency, size and cost improvements for appliance manufacturers facing increasing energy regulation demands.
The new GaNSense Motor Drive IC family targets a critical efficiency bottleneck in home appliances and industrial equipment. For appliance manufacturers under pressure from intensifying energy efficiency standards, the 4% efficiency improvement over silicon IGBTs directly impacts energy consumption ratings and operating costs throughout product lifetimes.
The bidirectional current sensing capability addresses a fundamental motor drive challenge - accurately measuring both driving and regenerative currents without power-wasting shunt resistors. This is particularly valuable in variable-load applications like washing machines, where motor current constantly changes direction during cycle transitions.
The 40% PCB footprint reduction provides significant design flexibility in space-constrained applications like dishwashers, refrigerator compressors, and heat pump systems. This space savings can be reinvested in other features or enable more compact appliance designs.
For industrial applications like circulation pumps and HVAC systems, the 15% system cost reduction combines with efficiency improvements to enhance total cost of ownership. The adjustable slew rates provide engineers flexibility to optimize for electromagnetic compatibility in sensitive environments or maximize efficiency where EMI concerns are less critical.
The integration of comprehensive protection features (short-circuit protection, over-temperature protection, 2kV ESD) addresses reliability demands in appliances expected to operate for 10+ years. By combining these protections with performance improvements, Navitas is removing barriers to GaN adoption in mainstream appliance platforms.
Fully integrated & protected GaN ICs with bi-directional loss-less current sensing delivers
TORRANCE, Calif., May 01, 2025 (GLOBE NEWSWIRE) -- Navitas Semiconductor (Nasdaq: NVTS), the only pure-play, next-generation power semiconductor company and industry leader in gallium nitride (GaN) power ICs and silicon carbide (SiC) technology, has announced a new family of GaNSense™ Motor Drive ICs targeting home appliances and industrial drives up to 600 W.
Specifically designed for motor drive applications, this fully integrated solution combines two GaN FETs in a half-bridge configuration with drive, control, sensing, and autonomous protection. Compared to legacy silicon IGBT solutions, this results in a
Key features include bidirectional lossless current sensing, which measures both positive and negative currents. This is critical in motor drives, given recirculating currents in the reverse direction between switching coil phases. The lossless sensing eliminates the need for external shunt resistors, resulting in higher efficiency, improved reliability, and a more compact design.
Turn-on and turn-off slew rates are fully adjustable, allowing designers to optimize EMI, performance, and maximize efficiency. The autonomous freewheeling function switches on the GaN IC upon detection of reverse current to reduce conduction losses, maximize efficiency, and reduce the size and cost of heatsinks.
The GaNSense Motor Drive IC family also includes several safety features such as high-and-low-side short circuit protection, over-temperature protection (OTP), and 2kV ESD on all pins.
The 650V family starts with NV6257 (2 x 170 mΩ, PQFN 6x8), NV6287 (2 x 170 mΩ, PQFN 8x10), and NV6288 (2 x 120 mΩ, PQFN 8x10), supporting drives up to 600 W.
Target applications focus on motor drives up to 600W, including air conditioners, heat pumps, washing machines, dryers, dishwashers, refrigerators, and hair dryers. For low-power industrial drives, applications range from pumps to circulators and fans.
The GaNSense Motor Drive ICs will be on display at PCIM 2025 (Hall 9, Booth #544, May 6th—8th, 2025). For more information and to schedule meetings, please click here.
