Product details

What this supervisor does on the rail

The open-drain output lets you connect it to a pull-up resistor at any logic level (1.8V, 3.3V, 5V) without level shifters, and it supports wired-OR connections with other reset sources. The SOT-23-3 package fits tight layouts, and the -40°C to 125°C junction temperature range covers industrial and automotive under-hood environments.

Open-drain output — wiring flexibility

Because the output is open drain, the reset signal can be pulled up to any voltage independent of the monitored rail.

Frequently asked questions

Does TLV803ED29DBZR have an open-drain output?

Yes, the reset output is open drain. This allows the output to be pulled up to any voltage level independent of the monitored supply.

Can TLV803ED29DBZR be used with 3.3V microcontrollers?

Yes, it is designed for monitoring 3.3V rails. The 2.93V threshold provides a typical 0.37V margin below the nominal 3.3V supply, which is sufficient for most 3.3V MCUs.

What is the replacement for TLV803ED29DBZR if discontinued?

There is no official replacement listed because the part is still active. If a second source is needed, the TLV803EA29VDBZR is a functional alternative with a 130ms minimum reset timeout instead of 33ms — check your timing requirements before substituting.
