RECOMMENDED OPERATING CONDITIONS
OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

Power-Fail Voltage Monitor Input Pin. nPFO goes low when PFI is lower
than 1.25V. If not used, connect PFI to GND or VCC.
Power-Fail Voltage Monitor Output Pin. nPFO goes low when PFI is lower
than 1.25V. nPFO remains high when PFI is more than 1.25V.
Watchdog Input Pin. If the WDI remains high or low for longer than the
watchdog timeout period (1.6s, TYP), the internal watchdog timer will
expire and nWDO will go low. The internal watchdog timer is kept clear
while a reset is asserted or WDI is three-stated. The timer is also cleared if
the WDI input is changed (on rising or falling edges). The watchdog
feature is disabled if the WDI is left open or if it is connected to a
three-stated buffer output. If it requires the SGM706B to switch WDI from
normal state to disable state, ensure that the WDI enters the high-Z state
from high level.
Active-Low Reset Output Pin. It delivers a 200ms (TYP) low pulse when
activated. nRESET will remain low if VCC is below the reset threshold or
nMR is logic low. It goes (or remains) low for 200ms after any of the
following events: VCC rises above the reset threshold or the nMR input
goes from low to high.
Watchdog Output Pin. If WDI can not reach a rising edge or a falling edge
in 1.6s, the watchdog timer will timeout. Meanwhile, nWDO is pulled low
and remains low until the watchdog timer is cleared. nWDO goes low
when VCC is below the reset threshold. nWDO is different from nRESET in
that it does not have a minimum pulse width. As long as VCC is higher than
the reset threshold, nWDO will immediately go high.
The exposed pad can be left floating.

SGM706B
8-Pin Microprocessor Supervisory Circuit
with Watchdog Timer and Manual Reset
DETAILED DESCRIPTION
Precise Reset Threshold
When the supply voltage drops significantly for the
power supply fault, the SGM706B can even operate
normally, which greatly reduces the possibility of
system failure. In addition, the internal reference
voltage accuracy of the SGM706B is very high, which
guarantees high reliability of the devices.
To ensure sufficient time for the power supply and
microprocessor to stabilize after power-up, a 200ms
(TYP) reset output will hold by the internal timer after
VCC exceeds the reset threshold voltage. Similarly, a
200ms (TYP) reset output will also exist after the power
supply recover from brownout or interruption that allows
the power supply and microprocessor to have enough
time to reach a steady state.
The SGM706B has an active-low nRESET output.
When VCC is as low as 1V during power-down, the
nRESET will keep output a low level. This not only
keeps the microprocessor shutdown when the supply
voltage falls, but also prevents the microprocessor from
occurring false actions when it powers up.
Watchdog
A watchdog timer is integrated in SGM706B. It must be
periodically triggered by a rising edge or a falling edge
of WDI. If the WDI cannot be triggered during the
timeout period (1.6s, TYP) and WDI is not three-stated,
the internal watchdog timer expires and nWDO goes
low.
The internal watchdog timer is cleared while a reset is
asserted or WDI is three-stated or WDI is fed on time
within the timeout period.
SG Micro Corp
www.sg-micro.com
Manual Reset (nMR)
The SGM706B provides a manual reset (nMR) function
that allows users to reset the system manually. It is an
active-low reset input with an internal pull-up resistor of
25kΩ. When the nMR is low, and for tRS (200ms, TYP),
after nMR returns high, the reset remains active. The
nMR can be driven by a CMOS logic or by a reset
switch shorting to GND. If not used, leave it open or
connect it to the VCC. When the device is far away from
the reset switch or used in a noisy environment, a
0.1μF capacitor is recommended to connect between
nMR and GND.
PFI, nPFO
For SGM706B, PFI (Power-Fail Input) and nPFO
(Power-Fail Push-Pull Output) pins can be used for
power-fail warning or monitoring a power supply of the
other device, and do not affect nRESET pin.
The internal voltage reference (1.25V) is used for
compare with PFI pin. Once the PFI voltage is lower
than the negative-going input threshold voltage, the
nPFO goes low. Once PFI voltage exceeds
positive-going input threshold voltage, the output goes
high. Connecting a resistor divider externally can
monitor any voltages above 1.25V.
To ensure that the PFI leakage current can be ignored
in comparision with the current through the resistor
divider and to minimize the resistor power consumption,
the sum of two resistors should be about 1MΩ. To
ensure the accuracy of the detection voltage, the
tolerance of the external resistor should be less than
1%. It is recommended to leave nPFO floating and
connect PFI to VCC pin if the PFI comparator is not
used.

APPLICATION INFORMATION
nRESET Valid to VCC = 0V
+12V
The nRESET of SGM706B stops sinking current and
becomes open circuit if VCC is below 1.0V. And if a
high-impedance input is connected to nRESET, the
input voltage will drift and be undetermined. To solve
the problem, it is recommended to use a 100kΩ resistor
between nRESET and GND.

PFI can also be used to monitor a negative supply rail.
The configuration is shown below. When the negative
rail is lower than some negative voltage which makes
VPFI between 0V and 1.25V, a low nPFO will not drive
the transistor to pull nMR low and nRESET will not be
triggered. When the negative rail is degraded, which
makes VPFI be higher than 1.25V, a high nPFO drives
the transistor to pull nMR low and trigger nRESET. And
the accuracy of this circuit is not high, depending on the
PFI threshold tolerance, VCC line and the resistors.

APPLICATION INFORMATION (continued)
The reset pin of some μC devices is bidirectional, such
as the Motorola 68HC11 series. Connecting the
SGM706B nRESET output to μC RESET output directly
may cause race and hazard. For example, if nRESET is
logic high and the RESET is logic low, connecting them
directly may result in indeterminate logic levels, even
damage the RESET pin of μC.
Therefore, a 4.7kΩ resistor is recommended to be
connected between nRESET and the μC reset I/O as
show in Figure 7. Besides, buffer the nRESET output to
reset other system components.
