Voltage supervisor with triple-threshold monitoring
The MAX6726KASVD4+ is a power supply monitor from Maxim Integrated that supervises three voltage rails simultaneously — thresholds at 1.575 V, 2.925 V, and an adjustable third channel — making it a single-package solution for multi-rail systems like FPGAs or SoCs where each core, I/O, and auxiliary supply needs independent monitoring. Reset outputs are both active-high and active-low push-pull, so the part can drive either polarity of reset logic without an external inverter — useful when interfacing to a mix of reset inputs on different ICs.
Reset timeout and temperature range
The reset timeout is a minimum of 1.12 seconds — long enough to let all power supplies settle after a brown-out or power-up before releasing the system from reset, which avoids premature start-up glitches on the controlled ICs.
