Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix '1AA' against the official datasheet to confirm the exact reset delay characteristics, as variations exist within the LM3880 family. Ensure the ordering part number matches the required package and temperature grade. Confirm RoHS compliance status and check for any recent PCN updates regarding marking or pin definitions before finalizing procurement orders.

Power Supply Controllers, Monitors Selection Notes

Select this component when a low-power, automotive-rated sequencer for three rails is required. The fixed delay feature simplifies design compared to programmable alternatives. Consider the SOT-23-6 footprint constraints and the open-drain output requirements for pull-up resistor integration. Verify that the 1.25 V threshold aligns with the monitored rail levels.
