Single-channel supervisor with 4.63 V threshold
The MAX6382XR46D3: The 140 ms minimum reset timeout holds the processor in reset long enough for the rail to stabilize after power-up or a brownout event. With a push-pull, totem-pole output, this supervisor drives the reset line directly without an external pull-up resistor — saving a component and a PCB trace on space-constrained boards. The active-high polarity suits designs where the processor's reset input is asserted high.
Industrial temperature range and SC-70-3 footprint
The SC-70-3 (SOT-323) package occupies roughly 2.0 x 2.1 mm on the board — a fit for sensor modules, remote I/O nodes, or any 5 V rail where board real estate is tight. The single-channel monitoring means one supervisor per rail. For multi-rail systems, a separate MAX6382 variant per voltage is the straightforward approach — no shared reference or sequencing logic on-chip.
