Reset T hreshold
The MAX814/MAX815 have fixed, factory-set reset
thresholds, signified by the first suffix letter in the part
number (see Figure 7 for more information on reset
ranges). The MAX816 has an adjustable reset threshold.
MAX814/MAX815 K-suffix parts have a minimum reset
threshold set to 4.75V, worst case. They are intended
for 5.0V systems with a ±4% or better power-supply tol-
erance design that must meet worst-case system para-
meters over time, temperature, line, and load variations.
Typically, the reset threshold (V
RT
) is greater than or
equal to the minimum IC operating voltage (V
ICMIN
).
The “K” series 1%-tolerance reset threshold allows a
larger range of power-supply tolerance. System ICs
that have a tight operating supply range, like the
386/486 μPs, need a RESET initiated at a minimum
threshold of 4.75V, worst case.
L-suffix parts have a minimum reset threshold set to
4.65V, worst case. They are intended for 5.0V systems
with a ±5% power-supply tolerance. Typically, the reset
threshold is less than or equal to the minimum power-
supply voltage, allowing system operation over the
complete power-supply range. A reset is initiated at
4.75V maximum. The 1% “L” version maximizes the
System IC Guard-Band Range.
N-suffix parts have a minimum reset threshold set to
4.50V, worst case. They are intended for 5.0V systems
with a ±10% IC system. Typically, the reset threshold
