- Industrial motor control systems
- High-side load switching applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'R2' matches the reel packaging requirement. Check for obsolescence status as indicated by lifecycle data. Ensure ESD precautions are followed during handling due to moisture sensitivity classification.
Selection Notes
Select this component when dual independent high-side switching with low conduction loss is required. Consider the PQFN-16 package for space-constrained designs. Evaluate the 4 mOhm resistance against thermal dissipation needs at target load currents. Verify compatibility with the 6 V to 27 V system voltage range.
