What this supervisor does on your board
The Analog Devices MAX6308UK00D3+T is a multi-voltage supervisor that monitors two separate supply rails and holds the system reset low for a minimum of 140 ms after both rails are valid. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor. Thresholds are adjustable or selectable, which lets you set the trip points to match your core and I/O voltages.
Where it fits — and where it doesn't
The 0°C to 70°C operating temperature range limits this part to commercial indoor equipment: office peripherals, consumer electronics, telecom line cards in climate-controlled rooms, and benchtop instrumentation. It is not rated for automotive, industrial motor drives, or outdoor enclosures where the ambient may drop below freezing or push past 70°C. Typical applications include supervising two supply rails in a dual-supply MCU or FPGA system, or monitoring a battery voltage alongside a regulated rail in portable gear. The adjustable threshold lets you fine-tune the trip point for a specific supply tolerance.
Sourcing and lifecycle
For a BOM line that needs a dual-voltage supervisor in a SOT-23-5 footprint, this part is a current-design fit with no LTB risk.
