The MAX6375XR26+ is a single-channel voltage detector from Analog Devices with a threshold of 2.63V. No external pull-up resistor is needed — the output drives the MCU reset pin directly. This saves one resistor per board and eliminates the risk of a floating reset line during power-up. The SC-70-3 package occupies roughly 2 mm × 2 mm — suitable for space-constrained designs where a supervisor in a larger SOT-23 would not fit.
Active lifecycle — no obsolescence risk for new BOMs
Because it monitors a single voltage, the BOM integration is straightforward: connect the monitored rail to VCC, the reset output to the processor reset pin, and ground. No external timing capacitor or resistor is required for the basic function — the internal delay is fixed.
