3-Pin Microprocessor Reset Circuits
below 1V, so does the IC’s ability to sink current at
RESET . Also, with any pullup, RESET will be pulled high
as V CC decays toward 0. The voltage where this occurs
depends on the pullup 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.

Package Information
For the latest package outline information and land patterns (foot-
prints), go to www.maximintegrated.com/packages . Note that a
“+”, “#”, or “-” in the package code indicates RoHS status only.
Package drawings may show a different suffix character, but the
drawing pertains to the package regardless of RoHS status.
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.
