Product details

Two-rail supervisor in a five-pin SOT-23

The MAX6420UK29+T from Maxim Integrated is a multi-voltage supervisor that monitors two separate supply rails and asserts an active-low reset when either falls below its threshold. One channel has a fixed 2.925V threshold; the second channel accepts an adjustable threshold set by an external resistor divider. The reset output is open-drain, meaning it can be wire-ORed with other reset sources on the same line. Reset timeout is adjustable via an external capacitor, giving the designer control over the power-up delay. The part operates from -40°C to 125°C and comes in a SOT-23-5 package.

Threshold and reset behaviour

The open-drain output can drive a pull-up resistor to various logic voltages.

Lifecycle and sourcing

No end-of-life notice or last-time-buy window has been announced. The part is ROHS3 compliant.

Frequently asked questions

What is the reset timeout for MAX6420UK29+T?

The reset timeout is adjustable/selectable via an external capacitor on the CT pin. There is no fixed factory timeout — the designer sets the delay to match the power-up sequence of the downstream device.

Is MAX6420UK29+T active low or active high?

The reset output is active low. It pulls low when a monitored voltage falls below its threshold and releases high after the timeout period once all rails are valid.
