Product details

Temperature range and deployment context

The MAX6821WUK: The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, simplifying the BOM for the downstream microcontroller or FPGA.

Housed in a 5-pin SOT-23-5 (SC-74A) package, the part occupies minimal board area and is suited for space-constrained designs — the 0.95mm pitch and 2.9mm body length fit under a low-profile enclosure. Surface-mount assembly with standard reflow profiles; no exposed pad or thermal vias required for this low-power supervisor.

Lifecycle and sourcing posture

RoHS non-compliant per the manufacturer's declaration; verify your assembly's exemption requirements before committing the BOM line.

Frequently asked questions

What is the reset timeout for the MAX6821WUK?

The reset timeout is a minimum of 140ms, ensuring the monitored rail has sufficient time to stabilise before the processor is released from reset.

What compliance documentation is available for the MAX6821WUK?

The manufacturer lists the MAX6821WUK as RoHS non-compliant.
