Product details

What the ADM693ARZ does on a 5 V board

The ADM693ARZ monitors a single supply rail and asserts a reset when the voltage drops to 4.4 V.

Reset output flexibility — active-high and active-low, open-drain and push-pull

This supervisor gives you both active-high and active-low reset outputs, each configurable as open-drain or push-pull. That covers the two common processor reset schemes — an active-low push-pull for most ARM and x86 cores, or an active-high open-drain for a wired-OR reset bus shared with other supervisors. No external pull-up or inverter needed for either case.

Housed in a 16-pin SOIC with a 7.50 mm body width (the wide-body SOIC-16), surface-mount only. Not rated for the full military range, but the industrial grade handles the environments most embedded systems see.

Lifecycle and compliance — no redesign pressure

No end-of-life notice on the horizon, no lead-free exemption expiry to track.

Frequently asked questions

What is the reset timeout of ADM693ARZ?

The reset timeout is a minimum of 35 ms. That is the time the part holds the processor in reset after the supply rises above the 4.4 V threshold — enough for most oscillators and PLLs to lock before the CPU starts executing.

What is the ADM693ARZ equivalent or replacement?

The ADM693ARZ-REEL is the same die and function, only packaged in Tape & Reel instead of Tube — a drop-in for reel-fed pick-and-place lines. The ADM691ARZ and ADM696ARZ are close siblings in the same family but differ in output configuration: the ADM696ARZ has push-pull outputs only, no open-drain option.

Is ADM693ARZ lead-free or RoHS compliant?

Yes, it is ROHS3 compliant — meets the latest RoHS exemption rules including the 10-substance restriction. No lead-free transition paperwork required for EU-market BOMs.
