Two-rail supervisor for industrial power sequencing
The Texas Instruments TPS3779CDRYR is a multi-voltage supervisor designed to monitor two independent supply rails and assert an active-low reset when either falls below its programmed threshold.
Threshold flexibility across supply combinations
With adjustable/selectable voltage thresholds, this supervisor can monitor common rail combinations such as 1.8 V and 3.3 V, or 2.5 V and 5.0 V, by setting external resistor dividers.
Housed in a 6-UFDFN package (6-SON, 1.45 mm x 1.0 mm), the TPS3779CDRYR is a surface-mount device that fits tight PCB layouts near the supervised processors.
No official second-source or direct replacement is listed, so dual-sourcing should be validated against the BOM position.
