Product details

Dual-rail supervisor for multi-voltage system monitoring

The Maxim MAX6718AUKSDD3+T is a multi-voltage supervisor that monitors two independent supply rails, with thresholds set at 0.788 V and 2.925 V. The active-low, push-pull output asserts reset when either monitored voltage falls below its threshold and holds reset for a minimum of 140 ms after both rails recover.

Wide temperature range suits industrial and automotive environments

Rated for -40°C to 125°C, the MAX6718AUKSDD3+T can be placed in outdoor telecom cabinets, factory-floor controllers, engine-bay electronics, and other thermally demanding locations without needing a separate temperature-grade variant.

Package and footprint — SOT-23-5

Housed in a SOT-23-5 package, the part is a surface-mount device that fits a compact five-pin footprint. The push-pull output eliminates the need for an external pull-up resistor.

Lifecycle and compliance

It is supplied in strip packaging, suitable for small-to-medium volume assembly or prototyping.

Frequently asked questions

What does the 140 ms minimum reset timeout mean for my design?

After both monitored voltages rise above their thresholds, the reset output holds low for at least 140 ms. This delay ensures the system's power supplies and oscillators have settled before the processor or FPGA begins executing code — essential for reliable power-up sequencing and brownout recovery.

What is the equivalent or alternative for MAX6718AUKSDD3+T?

No direct pin-compatible equivalent is listed in the manufacturer's cross-reference for this specific threshold combination. For a same-function supervisor with different thresholds, review the MAX6718 family variants. The part is active, so a direct replacement is not needed for production.
