Product details

What the MAX808MEPA is and where it fits

The battery-backup function (Type: Battery Backup Circuit) means this part also switches to a backup battery when the main supply fails, preserving the contents of a CMOS RAM or keeping the real-time clock alive — a feature not found in a basic reset generator.

Active lifecycle, RoHS non-compliant

It is, however, RoHS non-compliant (leaded solder finish), which means it cannot be used in new designs bound for the EU RoHS market unless an exemption applies. For legacy boards that already use leaded solder, this is the correct replacement part.

Frequently asked questions

Is MAX808MEPA RoHS compliant?

No, the MAX808MEPA is RoHS non-compliant. It uses a leaded (tin-lead) solder finish. For RoHS-required designs, look for a lead-free (Pb-free) variant in the same family.

What is the reset timeout of the MAX808MEPA?

The reset timeout is a minimum of 140ms. After the monitored voltage rises above the threshold, the reset output stays low for at least 140ms before releasing the processor.

What is the closest pin-compatible alternative to the MAX808MEPA?

The MAX808MEPA is a Maxim-specific ordering code. Within the same family, the MAX808CPA (8-PDIP, commercial temperature 0°C to 70°C) is pin-compatible but has a narrower temperature range. For a fully equivalent part with the same industrial temperature range, the MAX808EPA is the same die in the same package — verify the exact ordering code suffix for your temperature grade.
