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. It holds the processor in reset for a minimum of 35 ms after the supply returns above threshold.
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.
Package and temperature range
Housed in a 16-pin SOIC with a 7.50 mm body width (the wide-body SOIC-16), surface-mount only. The -40°C to 85°C industrial temperature range covers most factory-floor, outdoor telecom, and automotive-cabin applications. Not rated for the full military range, but the industrial grade handles the environments most embedded systems see.
Lifecycle and compliance — no redesign pressure
ADI lists the ADM693ARZ as Active with ROHS3 compliance. No end-of-life notice on the horizon, no lead-free exemption expiry to track. For a BOM line that needs a supervisor with battery-backup logic, this part is a stable choice — no forced redesign cycle from obsolescence.
