Nexperia ASFET for 36 V DC motors

There is growing demand for 36 V DC motors, often being used with multi-cell lithium-ion battery packs, in an increasing range of applications

There is growing demand for 36 V DC motors, often being used with multi-cell lithium-ion battery packs, in an increasing range of applications. From cordless power tools to outdoor power equipment and even e-bikes and scooters. To drive these demanding applications safely and efficiently requires MOSFETs that have been optimized for high current, strong SOA and rugged avalanche rating. Nexperia has also optimized them for efficiency with our 50/55 V ASFET range.
Key features

• Superjunction technology-enhanced SOA to withstand power dissipation due to short-circuit
• I_D of 200 A max. in a LFPAK56, enabling maximum torque from the motor
• Low R_DS(ON) characteristics deliver higher efficiency for longer battery life
• LFPAK brings a unique level of board level reliability and ruggedness

Additional features

• Nexperia’s Superjunction technology provides an  enhanced Safe Operating Area (SOA) to withstand power dissipation due to short-circuit faults
• I_D of 200 A (max) in an LFPAK56, enabling maximum torque from the motor and reliably managing high load and stall current conditions
• Potential UIS (unclamped inductive spiking) energy dissipation 20% lower than a comparable 60 V MOSFETs
• Nexperia’s low R_DS(on) characteristics deliver higher efficiencies, ensuring longer battery life
• As with all motor applications, there is a level of system vibration that cannot be dampened. LFPAK brings a unique level of board-level reliability and ruggedness.
• Many devices are offered in logic level allowing them to be switched directly from a microcontroller device.
