New MOSFET Combination Further Enhances System Efficiency for UAV Applications
Curve Semiconductors, a strong technology-oriented power chip supplier integrating design, R&D, production and sales, has launched an industry-leading, cost-effective and rigorously tested high-reliability SGT MOSFET product portfolio for UAV application solutions, combined with its strong technical strength and innovation capabilities in this field.
Drone Applications Place Stringent Requirements on MOSFETs
-
High power density and high current loading: Heavy-duty drone motors have high power, and MOSFETs need to have both high current carrying capacity and high-power density to reduce the size of the system
-
Low-impedance high-speed switching: MOSFETs with low on-resistance can reduce conduction losses, help improve system efficiency and battery life, and their fast-switching characteristics facilitate fast response of motor control signals, effectively ensuring accurate control and smooth flight
-
High-current quick breaking: When the drone is rapidly increasing (decreasing) or stalling, the current will increase instantaneously, so the MOSFET is required to have a wide SOA and high-current fast shutdown capability to avoid equipment stalling
To meet the stringent requirements of UAV applications for system efficiency, safety and reliability, the 30 ~ 150V MOSFET product portfolio recommended by Curve Semiconductors this time has been better trade-off, and the on-resistance has been further optimized under the premise of maintaining low Qg. When VGS=10V, the on-resistance range of this series of products is 0.43mΩ ~ 3.4mΩ, and the FOM value is 48 ~ 330.
Measured Data Results
After adjusting the gate RC ratio (Rg=110Ω，Cg=1nF), the rise time is kept close to the initial state, and the ringing problem is optimized. After 15 minutes of synchronous test burn-in, the MOSFET test case temperature was 41.3°C at an ambient temperature of 23°C.
The down-tube DS waveform rise time is increased from 50nS to 80nS and the dead time is 420nS.
Flagship Product - CMT10T02AHPDCQ
In response to the trend of high-power application of UAVs, Curve Semi has launched a new double-sided heat dissipation package, which can be connected to the heat sink in the most direct way through the top, and its heat dissipation capacity is three times higher than that of the bottom heat dissipation MOSFET, and the current carrying capacity is greatly improved.
Leading-edge SGT 100V PDFN5060 Double-sided heat dissipation
- It is the first product in China to achieve 100V PDFN5060-8L top gauge products, with an on-resistance of less than 2.0mΩ, which is comparable to international top suppliers.
- PDFN5060 double-sided heat dissipation 100V has a typical RDS(ON) value of 2.0mΩ, which is much lower than other competitors and has the lowest FOM(Qg) in the industry
