Datasheet	MAX815_MaximIntegratedProducts.pdf

The MAX814/MAX815/MAX816 are high-accuracy microprocessor (µP) supervisory circuits that provide power-on reset, watchdog, and power-fail functions.

They eliminate manual trimming and improve reliability in critical applications needing high-accuracy reset thresholds.

The RESET output is guaranteed to be in the correct state for VCC down to 1V.
