Single-rail supervisor for 5V MCU systems
The DS1811R-15+T&R is a single-channel voltage supervisor from the EconoReset family, designed to monitor a 5V supply rail and assert a reset signal when the voltage drops below 4.13V. The reset output is active low with an open-drain topology, so it can be pulled up to any logic voltage up to the absolute maximum of the device — useful for interfacing with 3.3V or 1.8V MCU reset pins without a level shifter.
Industrial temperature range and SOT-23 footprint
Store the reels in a dry environment — the SOT-23 package is not moisture-sensitive per JEDEC, but long-term humidity exposure can affect solderability.
Active lifecycle and compliance posture
The part is RoHS3 compliant (2015/863/EU), free of the ten restricted substances above the threshold limits.
The DS1811R-15+T&R is sourced through independent and authorized distribution channels.
