What the 2.93 V threshold and 140 ms timeout mean for your processor
The MAX823SEUK: This 140 ms window covers the power-up settling time of most MCUs and SoCs — the processor sees a clean, stable supply before the reset de-asserts. The push-pull, totem-pole output drives the reset input directly without an external pull-up resistor. The output stage sources and sinks current, so the reset line stays in a known state even if the processor's internal pull-up is disabled.
The part is RoHS non-compliant. Verify your assembly's RoHS exemption requirements before committing the BOM line.
Package and board-fit — SOT-23-5
The 5-pin surface-mount footprint fits a standard 0.95 mm pitch layout. The -40 to +125 °C operating temperature range covers industrial and automotive ambient conditions — the reset threshold stays within spec across the full temperature sweep.
