OPERATION
Output
The STM1061 Voltage Detector monitors system
voltages from 1.6V to 5V in 100mV increments.
The detector is designed to ignore fast transients

The STM1061has an open drain active-low output
which will sink current when output is asserted.
Connect a pull-up resistor from OUT to any supply
voltage up to 6V (see
resistor value large enough to register a logic low,
and small enough to register a logic high while all
of the input current and leakage paths connected
to the reset output line are being supplied. A 10k
pull-up is sufficient in most applications.
The advantages of open drain output is the ability
to connect more open drain outputs in parallel
(wired OR connections) as well as connect the
output to a power supply voltage different from

Negative-Going V
Undershoot
The STM1061 device is relatively immune to neg-
ative-going V

the transient increases (further below the thresh-
old), the maximum allowable pulse width decreas-
es. Any combination of duration and overdrive
which lies under the curve will NOT generate a re-
set signal.
