SGM706B
8-Pin Microprocessor Supervisory Circuit
with Watchdog Timer and Manual Reset
GENERAL DESCRIPTION
FEATURES
The SGM706B is an integrated microprocessor
supervisory device. Compared with the design using a
single IC or discrete components, this integration
design has the advantage of improving system stability
and accuracy. The SGM706B can be reset under
power-up, power-down or even voltage reduction
brownout conditions. When VCC is as low as 1V, the
reset output can still operate. And it also has a low-level
active manual reset nMR function.
● Ultra-Low Supply Current: < 1μA (TYP)
● Precision Supply-Voltage Monitor

The SGM706B provides an independent watchdog
monitoring circuit, which is activated when its WDI input
has not toggled for more than 1.6s.

● Voltage Monitor for Power-Fail or Low-Battery
Warning
When the power supply fails, the battery power is low,

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.

8-Pin Microprocessor Supervisory Circuit
with Watchdog Timer and Manual Reset
SGM706B
DETAILED DESCRIPTION
Precise Reset Threshold
Manual Reset (nMR)
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.
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.
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.
PFI, nPFO
For SGM706B, PFI (Power-Fail Input) and nPFO
(Power-Fail Open-Drain 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 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.
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.
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.
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.
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.

APPLICATION INFORMATION
nRESET Valid to VCC = 0V
+12V +5V
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

may cause race and hazard. For example, if nRESET is

Therefore, a 4.7kΩ resistor is recommended to be
