Procurement Notes

Verify the component status as End-of-Life (EOL) before procurement planning. Confirm that the DFN8 package suffix MN matches the required footprint. Ensure compatibility with existing PWM controllers such as the NCP6151. Validate that the 35 V boost voltage accommodation meets system requirements. Check for alternative sources if long-term supply stability is critical.

Selection Notes

Select this driver for applications requiring fast rise and fall times with minimal cross-conduction risk. It is suitable for systems needing direct interface with compatible PWM controllers like the NCP6151. The integrated bootstrap diode reduces external component count. Consider the thermal performance of the DFN8 package for heat dissipation needs in compact designs.
