Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package type before procurement. Confirm that the component adheres to RoHS compliance standards if halogen reduction is a project requirement. Ensure the selected variant corresponds exactly to the IPM-7 package dimensions specified in the datasheet to maintain mechanical compatibility with existing PCB layouts and thermal management systems.

Selection Notes

Select this module for applications requiring integrated gate driving and protection features to reduce design complexity. Consider the 4.0Ω maximum RDS(on) when calculating conduction losses for continuous currents up to 1.5A at 25°C case temperature. Evaluate the 16kHz PWM frequency limit and shoot-through blocking time against control signal requirements. Ensure adequate thermal dissipation paths are designed given the 39°C/W junction-to-ambient thermal resistance.
