Product details

4.65V threshold and the battery-backup handoff

The MAX691EWE+ monitors a single 5V rail with a threshold of 4.65V. This is useful when the reset input on the downstream processor is already pulled high or low internally.

Industrial temperature range and 16-SOIC footprint

Housed in a 16-SOIC wide-body package (7.50mm body width). The 1.27mm pitch is layout-friendly on a two-layer board; the wide-body footprint also helps with thermal dissipation when the part is switching the backup battery current.

Frequently asked questions

What is the reset timeout of MAX691EWE+?

The reset timeout is 35ms minimum. This is the period the part holds the reset outputs asserted after the monitored voltage rises above the 4.65V threshold, giving the backup battery or the main supply time to settle before the processor boots.

Is MAX691EWE+ compatible with 5V systems?

Yes, the 4.65V threshold is designed to monitor a nominal 5V supply rail. The part switches to battery backup when the rail drops below that level, making it a direct fit for 5V processor and memory systems that need an orderly power-down and restart.
