## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues
*Pitfall:* Inadequate heatsinking leading to thermal runaway
*Solution:* Implement proper thermal interface material and forced air cooling
*Recommendation:* Maintain junction temperature below 125°C with adequate derating
Gate Drive Problems
*Pitfall:* Insufficient gate drive current causing slow switching
*Solution:* Use dedicated gate driver IC with peak current >2A
*Recommendation:* Implement negative gate bias for improved noise immunity
EMI Concerns
*Pitfall:* High dv/dt causing electromagnetic interference
*Solution:* Implement snubber circuits and proper filtering
*Recommendation:* Use gate resistors to control switching speed
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires isolated gate drivers (e.g., IR2110, ACPL-332J)
- Compatible with 15V gate drive voltage
- Needs negative bias capability for optimal performance
Sensor Integration
- Temperature sensor output requires ADC interface
- Current sensing requires external shunt resistors
- Compatible with standard protection ICs
Control System Interface
- Works with common microcontrollers (DSP, FPGA, MCU)
- Requires optical isolation for high-side switches
- Compatible with standard PWM controllers
### PCB Layout Recommendations
Power Stage Layout
- Keep power traces short and wide (minimum 2 oz copper)
- Implement star grounding for power and signal grounds
- Place decoupling capacitors close to module pins
- Use multiple vias for thermal management
Gate Drive Circuit
- Route gate drive traces away from power traces
- Keep gate loop inductance minimal
- Use twisted pair or coaxial cables for gate connections
- Implement separate ground planes for gate drive
Thermal Design
- Provide adequate copper area for heatsinking
- Use thermal vias under the module
- Ensure proper airflow across the module
- Consider thermal expansion matching
EMI Reduction
- Implement proper shielding
- Use ferrite beads on gate drive inputs
- Route sensitive signals away from power traces
- Include proper filtering on all inputs
