## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues
- Pitfall : Inadequate heat sinking leading to thermal runaway
- Solution : Implement forced air cooling or liquid cooling for currents above 100A
- Verification : Monitor case temperature during operation, maintain below 85°C
Gate Drive Problems
- Pitfall : Insufficient gate drive current causing slow switching and excessive losses
- Solution : Use dedicated gate driver IC with minimum 4A peak current capability
- Implementation : Include local decoupling capacitors near gate pins
Parasitic Oscillations
- Pitfall : Layout-induced ringing during switching transitions
- Solution : Minimize loop inductance through tight layout and use of snubber circuits
- Mitigation : Implement RC snubber networks across drain-source terminals
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires drivers with 12-18V output range
- Compatible with isolated gate drivers for high-side applications
- Avoid drivers with slow rise/fall times (>50ns)
Sensor Integration
- Temperature sensor output requires ADC with 10-bit resolution minimum
- Current sensing resistors must handle high di/dt conditions
- Compatible with standard Hall-effect current sensors
Control System Interface
- Works with common microcontroller PWM outputs (3.3V/5V logic)
- Requires level shifting for high-side gate drive applications
- Compatible with standard protection circuit interfaces
### PCB Layout Recommendations
Power Stage Layout
- Use 4-6 layer PCB with dedicated power and ground planes
- Maintain minimum 100mil clearance for high
