Product details

Battery backup supervisor with 2.925V threshold

The MAX806SCSA: The minimum reset timeout is 140ms, holding the processor in reset long enough for the supply to stabilize after a brownout or power-up event.

Package, temperature grade, and compliance

This suits indoor, temperature-controlled equipment — office peripherals, telecom line cards, and industrial control panels with ambient air circulation. The part is RoHS non-compliant, indicating a legacy lead-bearing solder finish. This matters for designs that must meet RoHS exemption limits or for repair/rework of existing leaded assemblies. Production status is active — the MAX806SCSA remains in current manufacture by Analog Devices.

Frequently asked questions

What is the MAX806SCSA used for?

It is a battery backup supervisory circuit that monitors a single 3V supply rail. When the rail drops below 2.925V, it asserts an active-low reset signal with a 140ms minimum timeout, holding the processor in reset until the supply recovers.

Is the MAX806SCSA RoHS compliant?

No — the MAX806SCSA is RoHS non-compliant, indicating a lead-bearing solder finish. Confirm your assembly process and RoHS exemption requirements before specifying.

What is the closest pin-compatible alternative to the MAX806SCSA?

The part is a single-sourced supervisor in the 8-SOIC footprint; any replacement would require a PCB layout change.
