*Solution:* Follow ESD protocols and utilize the built-in protection diodes effectively
### Compatibility Issues with Other Components
Driver IC Compatibility
- Ensure gate driver IC can supply sufficient current for required switching speed
- Verify driver output voltage matches MOSFET requirements
- Check for shoot-through protection in half-bridge configurations
Microcontroller Interface
- Level shifting may be required when driving from 3.3V or 5V logic
- Consider gate driver ICs for fast switching applications
- Pay attention to rise/fall time requirements
Passive Component Selection
- Bootstrap capacitors must be properly sized for high-side configurations
- Snubber circuits may be necessary to reduce voltage spikes
- Decoupling capacitors should be placed close to the device
### PCB Layout Recommendations
Power Path Layout
