Product details

Triple-rail supervisor in a five-pin SC-70

The MAX6740XKWTD3+ is a low-power triple-voltage supervisor from Analog Devices that monitors three supply rails simultaneously: one fixed at 1.665V, one at 3.075V, and one adjustable threshold via an external resistor divider. The active-low reset output is open-drain, so it pulls low when any monitored voltage falls below its threshold and releases after a 150ms minimum timeout once all rails are valid. This lets it interface directly with any logic family's reset input without level-shifting.

Frequently asked questions

What supply rails does the MAX6740XKWTD3+ monitor?

It monitors three voltages: a 1.665V rail, a 3.075V rail, and one adjustable-threshold rail that you set with an external resistor divider. This covers common core, I/O, and auxiliary supply combinations in multi-voltage systems.

What package does the MAX6740XKWTD3+ come in?

It is supplied in a 5-lead SC-70 package, also known as SOT-353. The supplier device package is SC-70-5, a surface-mount footprint with 0.65mm lead pitch suited for compact PCB layouts.
