3.4V threshold, open-drain reset — what it means on the rail
The MAX6380UR34-T: The active-low, open-drain output allows the reset line to be shared with other open-drain devices on the same pull-up rail — common in multi-voltage supervisor designs where a common POR bus is required.
SOT-23-3 footprint and supply rails
Housed in the SOT-23-3 package (also known as TO-236-3 or SC-59), the MAX6380UR34-T occupies a small PCB footprint with a 1.5 mm pitch between the outer pins. The open-drain output requires an external pull-up resistor to the supervisor's supply rail — the resistor value sets the rise time on the reset line and the current sunk by the output during assertion. Because the device monitors a single voltage, the layout is straightforward: the VCC pin connects to the monitored rail, GND to the ground plane, and the output pin to the reset net with a pull-up. No external capacitors are required for the detector itself, though the monitored rail's own decoupling should follow the usual practice.
Active lifecycle and sourcing
The part is RoHS non-compliant per the current listing, which may affect procurement for assemblies requiring full RoHS exemption documentation. No direct pin-compatible second source is recorded in this data set, so BOM continuity depends on the MAX6380UR34-T itself or a board-level change.
