Three-rail supervisor in a six-pin SOT-23
The MAX6724AUTTGD3+ is a multi-voltage supervisor from Analog Devices that keeps an eye on three supply rails at once — 1.11 V, 3.075 V, and an adjustable threshold — and pulls the reset line low when any of them dips below its trip point. That three-channel supervision in a SOT-23-6 package is what makes this part useful for space-constrained automotive boards where you cannot afford a separate supervisor per rail.
What the three thresholds mean for your BOM
The three monitored voltages — 1.11 V, 3.075 V, and an adjustable input — map to the typical core, I/O, and auxiliary rails in an automotive ECU or sensor module. Active-low reset with push-pull output means no external pull-up resistor needed — the output drives high or low directly, which simplifies the layout and saves one component per supervisor channel.
Active production — no end-of-life scramble
No last-time-buy window to track, no successor to qualify — the BOM line stays stable as long as the design lives.
