below 1V, so does the IC’s ability to sink current at

RESET. Also, with any pull-up, RESET will be pulled

high as VCC decays toward 0. The voltage where this

occurs depends on the pull-up resistor value and the

voltage to which it is connected.

Benefits of Highly Accurate

Reset Threshold

Most µP supervisor ICs have 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 sup-

ply 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.

The MAX8_ _L/T/Z use highly accurate circuitry to

ensure that reset is asserted close to the 5% limit, and

long before the supply has declined to 10% below

nominal.
