Benefits of Highly Accurate Reset Threshold

Most µP supervisor ICs has reset threshold voltages between 5% and 10% below the

value of nominal sup-ply voltages. This ensures a reset will not occur within 5% of the

nominal supply, but will occur when the supply is 10% below nominal. When using ICs rated

at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is

between 5% and 10% low, and where the reset may or may not be asserted.
