Dual-threshold supervisor for multi-rail sequencing
The MAX6715UTRVD3-T from Analog Devices is a 2-channel multi-voltage supervisor that monitors two independent supply rails with thresholds of 1.575 V and 2.625 V. This lets it guard a 1.8 V core rail and a 2.5 V I/O rail simultaneously — typical for a mixed-voltage SoC or FPGA power tree where the core must be valid before the I/O bank enables. The reset output is active-low, open-drain, with a minimum reset timeout of 140 ms. An open-drain output lets multiple supervisors share a common pull-up resistor on the reset line — useful when a system needs a sequenced power-good signal from several monitors.
Package and temperature grade
Housed in a SOT-23-6 package (supplier device package same), it is a surface-mount part suited for compact PCB layouts.
