Dual-voltage supervisor with 4.63V threshold
The MAX6705LKA+ is a power supply monitor from Analog Devices that supervises two voltage rails, with the primary threshold set at 4.63V. This 120ms timeout gives the system time to stabilize before the processor starts executing code, which matters for designs where the power supply ramps slowly or has transient dips during startup.
Industrial temperature range and SOT-23-8 package
The SOT-23-8 package (supplier device package SOT-23-8) is a surface-mount footprint with 0.65mm pitch, common for voltage supervisors in space-constrained designs. The small outline means it fits on the back side of a PCB under a BGA or connector, but the thermal dissipation is limited — the ambient temperature rating assumes free air convection, not forced airflow.
