Product details

Three-voltage supervisor in a compact SOT-23-8

The SOT-23-8 package keeps the footprint small — useful when board space is tight and you need to supervise a core voltage plus an I/O rail and an auxiliary supply. The operating temperature range of -40°C to 125°C covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive electronics without derating.

Active lifecycle — no LTB clock ticking

The MAX6703MKA carries an active product status per the manufacturer's lifecycle record. For a BOM line that needs a supervisor for a multi-year production run, this part does not introduce obsolescence risk today. The RoHS compliance is listed as non-compliant, so verify your assembly house's exemption policy if you are building to a RoHS-mandated spec.

Frequently asked questions

What is the reset timeout of MAX6703MKA?

The reset timeout is a minimum of 140ms. After all monitored voltages rise above their thresholds, the reset output stays asserted for at least 140ms before releasing.

Does MAX6703MKA come in a different package?

The MAX6703MKA is offered only in the SOT-23-8 package (supplier device package SOT-23-8). No alternate package variant is listed for this order code.

What voltages does MAX6703MKA monitor?

It monitors three voltages: one fixed threshold at 4.38V and two adjustable thresholds that you set with external resistor dividers. This lets you supervise a 5V rail plus two lower-voltage rails like 3.3V and 1.8V.

Is there a replacement or equivalent for MAX6703MKA?

No direct replacement or equivalent is listed in the manufacturer's lifecycle record. The part is active, so no successor has been designated. For a pin-compatible alternative within the same family, cross-reference the MAX6703 series datasheet for other threshold options.
