The MAX6503UKN035-T from Maxim Integrated is a micropower temperature switch designed to assert a logic output when the die temperature crosses a factory-set threshold. This part is suited for overtemperature protection in battery-powered equipment, portable instruments, and other thermally constrained designs where quiescent current must stay low. The device is rated as active in the current lifecycle stage, meaning it remains available for new production builds and BOM allocation.
