How is the reset delay configured?

The delay can be set to 20ms (CT open), 300ms (CT to VDD), or user-defined (1.25ms to 10s) using an external capacitor on the CT pin.

What are the key features of this supervisor?

It offers 0.5% threshold accuracy, ultra-low 2.4µA quiescent current, and a manual reset (MR) input.

What should engineers review before using this part?

Verify the threshold voltage (3.07V for the G33 version) matches the system requirements and ensure the reset output is properly pulled up.

What are the sourcing risks?

The device is currently active and widely available, with no significant supply risks reported.
