The MAX6711MEXS+T from Maxim Integrated is a single-channel voltage supervisor that asserts a reset signal when the monitored supply drops below 4.38V. It holds the reset output low for a minimum of 140ms after the supply recovers, giving the processor time to initialize. The push-pull, active-low output drives directly into the reset pin of an MCU, FPGA, or SoC without an external pull-up resistor.
Push-pull output — no external pull-up needed
The push-pull (totem-pole) output drives both high and low, so the reset pin sees a clean logic level without a pull-up resistor. That saves one component per supervisor and eliminates a potential failure point. The active-low polarity means the output is low during reset and high when the supply is valid — standard for most MCU reset inputs.
