Three-rail supervisor in a SOT-23-8
The MAX6734KASDD3 is a multi-voltage supervisor that monitors three system rails simultaneously. It asserts an active-low, open-drain reset output when any monitored voltage drops below its threshold, and holds reset for a minimum of 140 ms after all rails recover. The three voltage thresholds are 0.788 V, 2.925 V, and an adjustable input. Packaged in a SOT-23-8, it fits compact PCB layouts in industrial control, telecom, and embedded systems.
Industrial temperature and surface-mount fit
Rated for -40°C to 85°C ambient, this supervisor is suited for factory-floor automation, outdoor base stations, and engine-bay electronics where temperature swings are routine. The SOT-23-8 package is a standard surface-mount footprint that reflows alongside other small-signal passives, keeping assembly straightforward.
Lifecycle and sourcing
It is RoHS non-compliant, so verify your assembly's exemption requirements. For a BOM line that needs this exact reset behavior and threshold set, we source and quote to order against an RFQ through independent distribution, with current availability and pricing confirmed at quote time.
