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
