The Maxim Integrated MAX8212CUA is a simple reset/power-on reset supervisor IC that monitors a single voltage rail and asserts an active-low reset signal when the supply drops below a user-set threshold. The threshold is adjustable via external resistors, giving the designer flexibility to set the trip point anywhere within the device's operating range rather than being locked to a factory-programmed value. The open-drain output allows wired-OR connection with other reset sources, common in multi-voltage systems where a single reset line must be shared across several supervisors. This limits the part to indoor, office, or controlled-environment equipment — not suitable for outdoor telecom cabinets, engine bays, or factory floors where ambient can swing below freezing or above 70°C. If the BOM calls for industrial temperature range, this is not the right fit.
The supplier device package is 8-µMAX.
RoHS compliance — check your BOM requirements
The MAX8212CUA is listed as RoHS non-compliant. For designs that must meet EU RoHS or similar environmental directives, this part will not pass a compliance audit. A lead-free alternative in the same function family may be available from Maxim (e.g., the MAX8212CUA+ with a plus suffix, which is typically RoHS compliant), but that variant is not covered in this listing. Verify the exact suffix against your BOM's RoHS requirement before committing the line.
