Product details

What this reset supervisor does on a 5V rail

The output is open-drain, active-low, so it can be wire-ORed with other reset sources or pulled up to a different voltage level if needed.

Package and mounting — hand-solderable SOT-223

Housed in a SOT-223-3 surface-mount package (TO-261-4 equivalent), this part has three visible pins and a large tab for thermal transfer.

Lifecycle and compliance — still in production, ROHS3

That keeps it usable for new designs targeting CE marking or similar regulatory schemes.

Frequently asked questions

Is DS1233DZ-5+T&R RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restriction on hazardous substances including lead, mercury, cadmium, and certain phthalates.

What is the reset timeout of DS1233DZ-5+T&R?

The reset timeout is 250ms minimum. After the supply rises above the threshold, the part holds reset low for at least 250ms before releasing it, giving the processor time to stabilize.

Is DS1233DZ-5+T&R active low reset?

Yes, the reset output is active low. The output goes low when the supply drops below the threshold and stays low through the timeout period after recovery.
