The MAX808NCSA+ is an Analog Devices battery backup circuit supervisor that monitors a single voltage rail with a 4.575V threshold and asserts an active-low reset when the supply dips below that level. With a 140ms minimum reset timeout, it holds the reset signal long enough for the monitored rail to stabilize after a brownout or power-up, preventing the downstream microcontroller or memory from operating during an undefined supply state.
The MAX808NCSA+ is ROHS3 compliant, confirming no restricted substances under the EU RoHS directive.
