10.8V rail monitor with push-pull output
The TPS3847108DBVR is a Texas Instruments simple reset IC that asserts a reset signal when the monitored supply drops below 10.8V. The active-low, push-pull output drives the reset line without needing an external pull-up resistor, simplifying the BOM for a single-voltage supervisor. The 4.5ms typical reset timeout is short enough to allow fast recovery from a brown-out event, yet long enough to debounce supply noise — a practical fit for 12V rails in industrial control or telecom line cards.
SOT-23-5 footprint and sourcing posture
Confirm the 10.8V threshold matches your monitored rail before committing — this is the single selection axis that cannot be adjusted externally.
Industrial temperature grade and operating boundary
The 85°C ceiling excludes under-hood automotive or downhole applications without a thermal derating margin.
