That covers most factory-floor, outdoor telecom, and automotive cabin applications. The small footprint leaves board space for other monitoring or protection circuitry.
It is not RoHS compliant per the current listing, so verify your assembly house's solder requirements if you are planning a lead-free reflow process.
The reset timeout is a minimum of 140ms. After all monitored voltages rise above their thresholds, the reset output remains active for at least 140ms before releasing.
The MAX6715 family includes multiple threshold variants in the same SOT-23-6 pinout. For a different voltage pair, check the MAX6715UTZ?D3 series where the '?' encodes the threshold code. The data sheet threshold table lists the available options.
The MAX6715UTZWD3 monitors rails at 1.665V and 2.313V. If your 3.3V rail needs supervision, this part does not monitor it directly. The open-drain output can be pulled up to 3.3V, so it can signal a 3.3V logic input, but the monitored thresholds are fixed at the values listed.
