Product details

Three-rail supervisor in a SOT-23-8

The Maxim Integrated MAX6734KASVD3 is a multi-voltage supervisor that monitors three supply rails simultaneously. 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. The part is housed in a SOT-23-8 package and rated for -40°C to 85°C operation, making it a fit for industrial control boards, base stations, and embedded systems where multiple power domains need sequencing or fault monitoring.

Package and mounting

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.

Lifecycle and sourcing

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.
