Supervisors Procurement Notes

Verify the specific suffix UR23 to confirm the 2.3V threshold voltage selection. Ensure the SC-70-3 package variant matches the target PCB footprint requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the exact part number against the latest datasheet revision to validate electrical specifications and operational limits.

Supervisors Selection Notes

Select this component when a fixed 2.3V threshold is required for low-voltage systems. The manual reset feature allows external intervention during debugging or fault conditions. Consider the 500nA current draw for battery life optimization in always-on applications. Verify that the open-drain output compatibility aligns with the downstream logic interface requirements.
