Product details

What this supervisor does on the board

This part is built for industrial environments — the -40°C to 85°C operating range covers outdoor telecom cabinets, factory-floor PLCs, and engine-bay controllers where a brownout or battery swap must not corrupt SRAM or leave a micro in an unknown state.

Active lifecycle — no LTB watch needed

The MAX690SESA carries an Active lifecycle status. You can qualify it into a new BOM without worrying about a forced redesign six months from now. Note the RoHS non-compliant flag — this part uses lead-bearing solder terminations. If your assembly line or end-market requires RoHS exemption (e.g., certain industrial or military contracts), this is acceptable; for full RoHS compliance, look at the lead-free suffix variants in the same family.

Frequently asked questions

What is the reset output type on MAX690SESA?

The reset output is active-low, push-pull (totem pole). It drives the reset line high or low without needing an external pull-up resistor, and it asserts low when the monitored voltage drops below the threshold.

What voltage threshold does MAX690SESA monitor?

It monitors a single supply rail with a threshold of 2.925V. That is the voltage at which the reset is asserted and battery-backup mode engages.

Is there a pin-compatible equivalent to MAX690SESA?

The MAX690 family includes several threshold and output variants. For a direct pin-compatible alternative with the same 2.925V threshold and active-low push-pull output, check the MAX690MJA or MAX690CPA — but confirm the package (CERDIP vs PDIP vs SOIC) and temperature grade match your BOM. No single universal substitute covers all variants; verify the specific order code against your design.
