What the 4.4V threshold means for your rail
The MAX692AESA: For a 5V supply, a 4.4V threshold gives roughly 12% undervoltage detection margin before the reset fires, which is tight enough to catch a sagging rail before logic errors propagate. The 140 ms minimum reset timeout holds the processor in reset long enough for the supply to stabilise after power-up, avoiding a premature release into a brownout condition.
Output drive and reset logic
Push-pull, totem-pole output with active-low reset — no external pull-up resistor needed, and the output drives directly into the microcontroller reset pin without a level translator.
Active production and compliance
RoHS non-compliant — the part contains lead in the solder finish, so it is excluded from RoHS-required assemblies unless a specific exemption applies. Verify your BOM's RoHS requirement before specifying.
