The STM1061 Voltage Detector monitors system

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 Figure 6., page 5). Select a
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

MAXIMUM RATING
Stressing the device above the rating listed in the
Absolute Maximum Ratings” table may cause per-
manent damage to the device. These are stress
ratings only and operation of the device at these or
any other conditions above those indicated in the
Operating sections of this specification is not im-
plied. Exposure to Absolute Maximum Rating con-
ditions for extended periods may affect device
reliability. Refer also to the STMicroelectronics
SURE Program and other relevant quality docu-
ments.

DC AND AC PARAMETERS
This section summarizes the operating measure-
ment conditions, and the DC and AC characteris-
tics of the device. The parameters in the DC and
AC characteristics Tables that follow, are derived
from tests performed under the Measurement
Conditions summarized in Table 4, Operating and
AC Measurement Conditions. Designers should
check that the operating conditions in their circuit
match the operating conditions when relying on
the quoted parameters.
