Product details

Two-voltage monitoring in a five-pin SOT-23

The MAX6306UK31D3+T is a multi-voltage supervisor from Analog Devices that monitors two supply rails and asserts an active-low reset when either falls below its threshold. The primary threshold is set at 3.08 V, with a second adjustable input that lets you set the lower rail's trip point with an external resistor divider.

Reset timing and board-level integration

The reset timeout is a minimum of 140 ms, which gives the downstream processor's oscillator and PLL enough time to stabilize before the supervisor releases the reset line. This fixed delay eliminates the need for an external timing capacitor.

Temperature grade and supply posture

It is not specified for industrial or automotive temperature grades.

Frequently asked questions

What is the MAX6306UK31D3+T used for?

It prevents a microcontroller or FPGA from running on an unstable or under-voltage supply.

What is the reset output type on the MAX6306UK31D3+T?

The reset output is active-low, open-drain. This means the output pulls low when a fault is detected, and an external pull-up resistor is required to hold the line high during normal operation.
