## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- *Pitfall*: Insufficient gate drive current causing slow switching and increased losses
- *Solution*: Use dedicated gate driver ICs capable of 2A peak current
- *Pitfall*: Gate oscillation due to long PCB traces and parasitic inductance
- *Solution*: Implement gate resistors (2.2-10Ω) close to MOSFET gate pin
Thermal Management
- *Pitfall*: Inadequate heatsinking leading to thermal runaway
- *Solution*: Calculate thermal impedance and use appropriate heatsink with thermal interface material
- *Pitfall*: Poor PCB layout affecting thermal dissipation
- *Solution*: Use thermal vias and adequate copper area for heat spreading
Protection Circuitry
- *Pitfall*: Missing overcurrent protection during fault conditions
- *Solution*: Implement current sensing with desaturation detection
- *Pitfall*: Voltage spikes from inductive loads exceeding VDS rating
- *Solution*: Use snubber circuits and TVS diodes for voltage clamping
### Compatibility Issues
