Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (01TN48E) against official Lattice documentation to confirm package type, temperature grade, and tape-and-reel configuration. Ensure compatibility with existing board layouts and programming interfaces. Confirm that the 2.8 V to 3.96 V operating range aligns with system requirements. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer.

Power Supply Controllers, Monitors Selection Notes

Select this component when a compact solution for managing multiple power rails is required without external discrete logic. The integrated CPLD reduces bill-of-materials complexity by handling sequencing and supervisory logic internally. Consider the 10-bit ADC and I2C interface if digital monitoring and remote configuration are necessary. Evaluate the wide supply voltage range and industrial temperature rating for robustness in demanding environments.
