It monitors thresholds of 2.5V, 3.3V, 5V, or an adjustable level, and pulls its open-drain output low when any monitored rail drops below its threshold, holding the reset for a minimum of 140ms after all rails return good. That open-drain output lets you wire-OR it with other supervisors or a manual reset button without contention. If your board lives in a motor drive enclosure, an outdoor telecom cabinet, or anything with an engine bay, the 0°C floor rules it out — you'd need an industrial- or automotive-rated supervisor. The scorch mark on a failed board in a heated server room is exactly the kind of failure this part won't see. No last-time-buy deadline to track, no scramble for obsolete-stock brokers. If you're doing a board repair and need a single piece, the cut-tape variant (CTS8#PBF) is the same silicon; the TRMPBF reel is what the pick-and-place wants. ## Active-low, open-drain — wire-OR friendly The reset output is active low and open drain, meaning it can sink current to ground but cannot source it. That's the standard supervisor output type: you pull it up to the monitored rail or the reset input's Vih with an external resistor. Multiple open-drain outputs can share a pull-up, so if your board already has a watchdog timer or another supervisor, you can tie their outputs together for a combined reset signal. The 140ms minimum reset timeout gives most power supplies time to stabilize after a fault clears.","metaTitle":"LTC2906CTS8#TRMPBF Multi-Voltage Supervisor, Active Low","metaDescription":"LTC2906CTS8#TRMPBF Analog Devices multi-voltage supervisor monitors 2.5V, 3.3V, 5V, Adj rails.
