Product details

Push-Pull output — no external pull-up needed

The reset output is active low, push-pull, totem pole. That means the output drives high or low without requiring an external pull-up resistor — a clean signal to the microcontroller reset pin with no extra BOM component. The push-pull stage also eliminates the weak pull-up current that open-drain outputs need, simplifying the layout in the SOT-23-3 footprint.

Active lifecycle — no obsolescence risk for new designs

The ADM6346-46ARTZ-R7 carries an active product status and is ROHS3 compliant.

Frequently asked questions

What is the reset timeout of ADM6346-46ARTZ-R7?

The reset timeout is 100ms minimum. That is the time the part holds the reset pin active after the supply voltage rises above the 4.63V threshold, giving the system clock and power rails time to stabilize before the processor starts executing code.

Is ADM6346-46ARTZ-R7 compatible with 3.3V systems?

No — the 4.63V threshold is designed for monitoring a 5V supply rail. For a 3.3V system, look at the ADM6326 family, which offers lower threshold options such as the ADM6326-26ARTZ-R7.

What is the equivalent of ADM6346-46ARTZ-R7?

The closest functional equivalent within the same family is the ADM6326-26ARTZ-R7, which shares the same simple reset/power-on reset type, active low push-pull output, and SOT-23-3 package, but with a different threshold voltage. For a direct 4.63V threshold replacement, the ADM6316CY46ARJZ-R7 is a peer with a 140ms minimum reset timeout.
