Focus MOSFET application – Electric Power Steering

Motor power depends on vehicle size and performance. MOSFETs are configured in 3-phase bridge arrangements to drive the BLDC motor.

The system must be capable of handling worst-case current and thermal surges caused by the torque assistant pulses.

Key MOSFET Requirements:

• Low on-resistance
• Low thermal resistance
• High surge current capacity
• Flexible packaging solutions
• Guaranteed repetitive avalanche capability

D2PAK are ideally suited to provide high power density and surge current capability required for power steering systems.

Main benefits:

• Lowest on-resistance
• Lowest thermal resistance
• Highest current handling capability
• Guaranteed repetitive avalanche rating

I2PAK & TO-220 provide flexible solutions for power steering systems where through-hole mounting is adopted.

Main benefits:

• Separate current and thermal paths
• Clamp, screw or solder mounting
• Low on-resistance
• High current handling capability
