Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package variant matches the required MultiPowerSO-30 footprint for PCB layout compatibility. Ensure thermal management solutions align with the 150°C junction temperature rating under expected load conditions. Cross-reference the datasheet revision date to confirm technical parameters have not changed since initial publication.

Selection Notes

Select this component when designing brushed DC motor drivers requiring high current capacity in an automotive environment. The integrated nature reduces external component count compared to discrete solutions. Consider the 18mOhm on-resistance for efficiency calculations and thermal dissipation requirements. The 20kHz operating frequency suits standard PWM control schemes without excessive switching losses.
