Product details

The MAX818MCSA+ is a single-channel battery backup supervisor IC from Analog Devices. The 4.4V threshold targets 5V nominal rails — the supervisor trips before the rail falls below the minimum operating voltage of 5V logic, preventing undefined states in the processor or memory during brownout or power-down.

Package and temperature grade

This limits deployment to indoor, temperature-controlled environments — not suitable for automotive or extended industrial ambient without active cooling.

Listed as Active in production with ROHS3 compliance.

Frequently asked questions

What is the reset timeout of the MAX818MCSA+?

The reset timeout is a minimum of 140ms. The reset output remains asserted for at least this duration after the monitored voltage rises above the 4.4V threshold.
