Dual-threshold supervisor for multi-rail systems
The MAX6354TZUK-T is a multi-voltage supervisor from Analog Devices that monitors two separate supply rails with thresholds at 2.32 V and 3.08 V. This makes it a fit for systems where a core logic rail (say 2.5 V) and an I/O rail (3.3 V) need independent supervision — if either dips below its threshold, the part asserts a reset to hold the system in a known state. The 100 ms minimum reset timeout gives the power supplies time to settle before the processor starts executing code.
SOT-23-5 footprint and industrial temperature range
Housed in a SOT-23-5 package (SC-74A, SOT-753 equivalent), the MAX6354TZUK-T takes up minimal board area — about 2.9 mm × 1.6 mm. The surface-mount footprint is standard for small-signal supervisors, so layout from existing designs or reference patterns carries over without a board spin. That means it works in factory-floor controllers, outdoor telecom gear, and automotive cabin electronics without needing a wider-range part.
Note that this part is listed as RoHS non-compliant. If your assembly requires RoHS exemption or a fully compliant bill, verify the date-code requirements or consider a lead-free variant in the same family.
