Procurement Notes

Verify the specific suffix 'E' against official onsemi documentation to confirm environmental compliance status. Confirm that the 19-SSIP package matches your PCB footprint requirements. Check for end-of-life notifications or product discontinuance notices as this series may have limited availability. Ensure substrate specifications meet thermal management needs for the intended application environment.

Selection Notes

Select this component when a hybrid IC solution is required for bidirectional brushed DC motor control. Compare output current capabilities and voltage ranges against other STK681 variants like the 352-E or 360-E. Evaluate thermal performance requirements relative to the 2.8 W power dissipation limit. Consider the need for external current sensing components to fully utilize the current control feature.
