Product details

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. Housed in a 4-pin SC-70-4 (SC-82A/SOT-343) package, it fits on tight PCB layouts where board area is at a premium.

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.

Temperature range and environment

Rated for -40°C to 125°C ambient, this supervisor handles industrial enclosures, outdoor telecom cabinets, and under-hood automotive electronics.

Frequently asked questions

Is MAX6711MEXS+T active low output push-pull?

Yes, the output is active-low push-pull (totem pole). It drives low during reset and high when the supply is valid, with no external pull-up resistor required.

Can MAX6711MEXS+T be replaced with MAX6711EXS+T?

The MAX6711EXS+T is a different variant with a different threshold voltage. The MAX6711MEXS+T has a 4.38V threshold; the MAX6711EXS+T uses a different trip point. They are not direct drop-in replacements without verifying the supply voltage.
