Product details

Three-rail supervisor in a SOT-23-8

It asserts a reset output (active low, open drain) when any monitored voltage drops below its threshold, and holds reset for a minimum of 140 ms after all rails return above threshold. The three monitored thresholds are 1.575 V, 2.925 V, and an adjustable input — covering common core, I/O, and auxiliary voltages in mixed-voltage designs.

SOT-23-8, surface-mount. The supplier device package is the same SOT-23-8. No special footprint beyond the standard SOT-23-8 land pattern; fine for hand-assembly or reflow.

It is RoHS non-compliant per the listing, so verify your assembly process if RoHS exemption is required.

Frequently asked questions

What are the threshold voltages of MAX6734KASVD3?

The fixed thresholds cover 1.8 V and 3.3 V rails; the adjustable input can be set with an external resistor divider for other voltages.

Does MAX6734KASVD3 have an open drain output?

Yes, the reset output is open drain (or open collector). It requires an external pull-up resistor to the reset rail.

Is MAX6734KASVD3 a direct replacement for MAX6734KASVD2?

Both are in the MAX6734 family with the same SOT-23-8 package and 3-channel supervision. The difference is the fixed threshold set: the KASVD3 variant monitors 1.575 V and 2.925 V, while the KASVD2 monitors a different pair. Verify your rail voltages against the threshold table before substituting.
