Supervisors Procurement Notes

Verify component authenticity through authorized onsemi channels or certified distributors. Confirm RoHS compliance status and check for obsolescence notices, as some variants may be nearing end-of-life. Ensure the specific suffix matches required packaging and temperature grades before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise 2.6 V threshold detection is required alongside ultra-low power constraints. Consider the programmable delay feature if system startup sequences demand specific timing margins. Verify that the TSOP-5 package fits the available PCB footprint and that the operating temperature range meets environmental requirements.

Supervisors Part Context

Part of the NCP302 second-generation family of voltage detectors. Designed specifically for applications where minimizing standby current is critical. Shares architectural similarities with other NCP302 variants but differs in threshold voltage and specific pin configurations.

Supervisors Replacement Considerations

Check for direct substitutes within the NCP302 series with adjusted threshold voltages. Verify pin compatibility and electrical specifications against alternative voltage supervisors from onsemi or other manufacturers before substitution.
