FEATURES
RESET Output
The SP705-708/813L/813M series provides
four key functions:
1. A reset output during power-up, power-down
and brownout conditions.
2. An independent watchdog output that goes
LOW if the watchdog input has not been toggled
within 1.6 seconds.
3. A 1.25V threshold detector for power-fail
warning, low battery detection, or monitoring a
power supply other than +5V.
4. An active-LOW manual-reset that allows
RESET to be triggered by a pushbutton switch.
A microprocessor's reset input starts the µP
in a known state. The SP705-708/813L/813M
series asserts reset during power-up and
prevents code execution errors during powerdown or brownout conditions.
On power-up, once VCC reaches 1V, RESET is
a guaranteed logic LOW of 0.4V or less. As VCC
rises, RESET stays LOW. When VCC rises
above the reset threshold, an internal timer releases RESET after 200ms. RESET pulses
LOW whenever VCC dips below the reset threshold, such as in a brownout condition. When a
brownout condition occurs in the middle of a
previously initiated reset pulse, the pulse continues for at least another 140ms. On powerdown, once VCC falls below the reset threshold,
RESET stays LOW and is guaranteed to be 0.4V
or less until VCC drops below 1V.
The SP707/708 devices are the same as the
SP705/706 devices except for the active-HIGH
RESET substitution of the watchdog timer. The
SP813L is the same as the SP705 except an
active-HIGH RESET is provided rather than an
active-LOW RESET. The SP705/707/813L
devices generate a reset when the supply voltage
drops below 4.65V. The SP706/708/813M
devices generate a reset below 4.40V.
The SP707/708/813L/813M active-HIGH
RESET output is simply the complement of the
RESET output and is guaranteed to be valid with
VCC down to 1.1V. Some µPs, such as Intel's
80C51, require an active-HIGH reset pulse.
The SP705-708/813L/813M series is ideally
suited for applications in automotive systems,
intelligent instruments, and battery-powered
computers and controllers. The SP705-708/813L/
813M series is ideally applied in environments
where monitoring of power supply to a µP and its
related components is critical.
Watchdog Timer
The SP705/706/813L/813M watchdog circuit
monitors the µP's activity. If the µP does not
toggle the watchdog input (WDI) within 1.6
seconds and WDI is not tri-stated, WDO goes
LOW. As long as RESET is asserted or the WDI
input is tri-stated, the watchdog timer will stay
cleared and will not count. As soon as RESET
is released and WDI is driven HIGH or LOW,
the timer will start counting. Pulses as short as
50ns can be detected.
THEORY OF OPERATION
The SP705-708/813L/813M series is a
microprocessor (µP) supervisory circuit that
monitors the power supplied to digital circuits
such as microprocessors, microcontrollers, or
memory. The series is an ideal solution for
portable, battery-powered equipment that
requires power supply monitoring. Implementing
this series will reduce the number of components
and overall complexity. The watchdog functions
of this product family will continuously oversee
the operational status of a system. The operational
features and benefits of the SP705-708/813L/
813M series are described in more detail below.

Typically, WDO will be connected to the
non-maskable interrupt input (NMI) of a µP.
When VCC drops below the reset threshold,
WDO will go LOW whether or not the watchdog timer has timed out. Normally this would
trigger an NMI but RESET goes LOW simultaneously, and thus overrides the NMI.
+5V
VCC
If WDI is left unconnected, WDO can be used as
a low-line output. Since floating WDI disables
the internal timer, WDO goes LOW only when
VCC falls below the reset threshold, thus functioning as a low-line output.

Ensuring a Valid RESET Output Down to
VCC = 0V
Power-Fail Comparator
The power-fail comparator can be used for
various purposes because its output and
noninverting input are not internally connected.
The inverting input is internally connected to a
1.25V reference.
When VCC falls below 1V, the SP705/706/707/
708 RESET output no longer sinks current, it
becomes an open circuit. High-impedance
CMOS logic inputs can drift to undetermined
voltages if left undriven. If a pull-down resistor
is added to the RESET pin, any stray charge or
leakage currents will be shunted to ground,
holding RESET LOW. The resistor value is not
critical. It should be about 100KΩ, large enough
not to load RESET and small enough to pull
RESET to ground.
To build an early-warning circuit for power
failure, connect the PFI pin to a voltage divider
as shown in Figure 16. Choose the voltage
divider ratio so that the voltage at PFI falls
below 1.25V just before the +5V regulator drops
out. Use PFO to interrupt the µP so it can
prepare for an orderly power-down.
Manual Reset
Monitoring Voltages Other Than the
Unregulated DC Input
The manual-reset input (MR) allows RESET to
be triggered by a pushbutton switch. The switch
is effectively debounced by the 140ms minimum RESET pulse width. MR is TTL/CMOS
logic compatible, so it can be driven by an
external logic line. MR can be used to force a
watchdog timeout to generate a RESET pulse
in the SP705/706/813L/813M. Simply connect
WDO to MR.
Monitor voltages other than the unregulated DC
by connecting a voltage divider to PFI and
adjusting the ratio appropriately. If required,
add hysteresis by connecting a resistor (with a
value approximately 10 times the sum of the
two resistors in the potential divider network)
between PFI and PFO. A capacitor between PFI
and GND will reduce the power-fail circuit's

sensitivity to high-frequency noise on the
line being monitored. RESET can be used to
monitor voltages other than the +5V V CC
line. Connect PFO to MR to initiate a RESET
pulse when PFI drops below 1.25V. Figure 17
shows the SP705/706/707/708 configured to
assert RESET when the +5V supply falls below
the RESET threshold, or when the +12V supply
falls below approximately 11V.
Interfacing to mPs with Bidirectional
RESET Pins
µPs with bidirectional RESET pins, such as the
Motorola 68HC11 series, can contend with the
SP705/706/707/708 RESET output. If, for
example, the RESET output is driven HIGH and
the µP wants to pull it LOW, indeterminate
logic levels may result. To correct this, connect
a 4.7KΩ resistor between the RESET output and
the µP reset I/O, as shown if Figure 19. Buffer
the RESET output to other system components.
Monitoring a Negative Voltage Supply
The power-fail comparator can also monitor a
negative supply rail, shown in Figure 18. When
the negative rail is good (a negative voltage of
large magnitude), PFO is LOW. By adding the
resistors and transistor as shown, a HIGH PFO
triggers RESET. As long as PFO remains HIGH,
the SP705-708/813L/813M will keep RESET
asserted (where RESET = LOW and RESET =
HIGH). Note that this circuit's accuracy depends on the PFI threshold tolerance, the VCC
line, and the resistors.

Applications
Unlike the DS1232, the SP705-708/813L/813M
series has a separate watchdog output pin WDO
which can be simply connected to the MR input
to generate a Reset signal. The DS1232 has pin
selectable features, while the SP705-708/813L/
813M series has more fixed functions of reset
threshold and watchdog time-out delay. For
most applications, the fixed functions will be
preferred, with the benefit of reduced cost due to
a less complex part. In addition, the SP705-708/
813L/813M series has a power fail input and
output function not available with the DS1232
that is useful for monitoring systems with
unregulated supply voltages. The SP705-708/
813L/813M series is available in one of the
industry's smallest space-saving package sizes,
the µSOIC.
The SP705-708/813L/813M series offers
unmatched performance and the lowest power
consumption for these industry standard devices.
Refer to Figures 20 and 21 for supply current
performance characteristics rated against
temperature and supply voltages.
Table 2 shows how the SP705-708/813L/813M
series can be used instead of the Dallas
Semiconductor DS1232LP/LPS. Table 2
illustrates to a designer the advantages and tradeoffs of the SP705-708/813L/813M series
compared to the Dallas Semiconductor device.
While the names of the pin descriptions may
differ, the functions are the same or very similar.
