Supervisors Procurement Notes

Verify the specific reset threshold voltage (2.63 V) matches your system requirements. Confirm the SOT-23-5 package footprint aligns with your PCB layout. Ensure the operating temperature range (-40°C to +125°C) suits your environmental conditions. Check for AEC-Q100 qualification if used in automotive contexts. Validate that the open-drain output configuration fits your downstream logic interface.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for system supervision. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the 140 ms reset delay against your microcontroller startup time requirements. Verify compatibility with the 1 V to 5.5 V input voltage range. Assess the need for manual reset functionality in your application design.
