DESCRIPTION
SP6340 and SP6342 Dual µPower Supervisory Circuit Family is a family of microprocessor
reset supervisory circuits with multiple reset voltages. The family provides low voltage
monitoring ability for up to two supplies with two precision factory-set thresholds. These
circuits perform a single function: if any of the input supply voltages drops below its
associated threshold, reset outputs are asserted. Products in the family offer watchdog
functionalities. SP6340 and SP6342 are packaged in a 6-pin TSOT package. All devices are
fully specified over -40oC to +85oC temperature range.

PIN DESCRIPTION
Pin #
Name
V1
Description
First supply voltage input. Also powers internal circuitry. Trip
threshold voltage internally set.
1
2
V2
Second supply voltage input. Trip threshold voltage internally set.
Watch-Dog Input pin. When no transition is detected at the WDI pin
for the duration of WDI timeout period, reset is asserted. WDOB
remains at “LOW” logic level after watchdog timeout period is
expired and it remains “LOW” until WDI makes a transition.
RST/RSTB output is not affected by the watchdog functionality in the
parts with separate WDOB output. The watchdog timer clears
whenever the reset is asserted or a transition is observed at WDI pin.
3
WDI
Watch Dog Output. Open-Drain or CMOS, active LOW. If WDI
remains at “HIGH” or “LOW” logic level for longer than the
watchdog timeout period, the internal watchdog timer overflows and
WDOB is asserted. WDOB does not de-assert until the watchdog is
cleared via transition at the WDI pin. Another scenario for WDOB to
assert is when the reset output is asserted due to an under-voltage
V1 or V2 condition. WDO de-asserts without a reset timeout period.
Floating WDI will not disable watchdog timer in devices with
dedicated WDOB output. Open-drain WDOB outputs require an
external pull-up resistor. CMOS outputs are referenced to V1.
4
WDOB
5
6
GND
Common ground reference pin.
Reset output. Open-Drain or CMOS, active high or low. Reset is
asserted when any of the supply inputs is below its trip threshold. It
stays asserted for 200 ms (typical / default) after the last supply input
traverses its trip threshold. Reset is guaranteed to be in the correct
state for V1>0.9V. RSTB asserts when V1 or V2 drop below their
corresponding reset thresholds. RSTB remains asserted for the
reset timeout period after V1 and V2 exceed their corresponding
reset thresholds. Open-drain outputs require an external pull-up
resistor. CMOS outputs are referenced to V1.

Understanding and Selecting a Multi-Voltage
Introduction
The primary function of a microprocessor (µP) supervisor circuit is to ensure that
the input supply voltage of a microprocessor is at proper levels during power up,
power down and brownout conditions. If the input supply voltage to a
microprocessor is below its required operating range, it could cause code-
execution errors, memory corruption and latch up. The supervisor will constantly
monitor the input supply to the microprocessor, and in the event this supply
voltage falls below a certain threshold, the RESET output will be asserted. Many
of today’s power products require several different voltage rails for powering
various components. The microprocessor itself can have a separate core voltage
and logic voltage. Other components such as DSPs, ASICs and microcontrollers
can have their own unique voltage requirements. To service this demand of
monitoring multi-voltage systems, Sipex has developed the SP6330 family. The
SP6330 family is a series of multi-voltage supervisors that offer monitoring of up
to 4 separate supplies and are equipped with specialized features. A complete
listing of products and features are listed in Figure 4 at the end of this note.

Inputs to the SP6330 Family
The SP6330 family has the ability to monitor up to 4 different voltages. Two of
these inputs (V1 and V2) have precision factory-set thresholds while the
remaining two inputs (V3 and V4) are adjustable. V3 and V4 inputs allow the user
to customize two additional supply thresholds by means of an external divider.
The threshold for V3 and V4 inputs is 0.5Volts. The V1 input supplies power to
the device and will have the highest threshold for a given application; its
minimum operating voltage for is 1.8V. The factory set threshold range for V1
and V2 inputs are shown in Figure 1.

Reset Output – RST or RSTB
The reset output can be either active low or active high depending on each
device. The reset output can also be either open-drain or push-pull outputs. The
open drain output requires an external pull-up resistor to V1 for normal operation.
The output high voltage (VOH) of the reset output will be approximately equal to
the V1 input voltage.
Reset Timeout Period
The reset timeout period is a built-in time delay for the reset output. This timeout
period is activated at power up or when all monitored voltages have risen above
their respective thresholds. Reset timeout period for the SP6330 family is offered
in four different time intervals: 50ms, 100ms, 200ms and 400ms. The actual
selection of timeout period depends on the applications requirements of the
system voltage settle time. The reset timeout period is used to ensure that all
voltage rails and system clocks have stabilized prior to executing code to prevent
errors or data corruption.

Manual Reset Input (Active Low) – MRIB
The manual reset input allows the user to manually trigger a reset when
monitored voltages are within tolerance. This is useful for resetting the
microprocessor when it locks up due to software issues. A push-button type
switch can be used to allow the user to trigger a reset externally. However, since
a push button switch will bounce several times, a debounce element is needed.
The manual reset input signal may also be a logic signal from an I/O line,
watchdog timer or a power fail output.
Watchdog Input – WDI
The watchdog checks for proper software execution. If the software locks up or
enters into an unwanted, loop the watchdog timer can either assert a reset output
or a watchdog output. Some members of the SP6330 family offer a watchdog
output while others do not. The watchdog has an internal timer that has a typical
watchdog timeout period of 1.6 seconds. If the watchdog input (WDI) does not
detect a transition within 1.6 seconds, a reset or watchdog output (WDO) will be
generated. The watchdog input is usually connected to an I/O line for monitoring
software activity. The watchdog circuit is useful for generating a reset or Non-
Maskable Interrupt (NMI) signal during software lock up conditions without
human intervention. Floating the WDI will disable the watchdog feature.
Watchdog Output (Active Low) – WDOB
The Watchdog output is active low and can be either an open drain or push-pull
output. If WDI remains at “HIGH” or “LOW” logic level for longer than the
watchdog timeout period, the internal watchdog timer overflows and the WDOB
will be asserted. Additionally, if the reset output is asserted due to an under-
voltage condition, at any voltage input the WDOB would also be asserted.
Floating WDI will not disable the watchdog timer in devices with dedicated
WDOB output.
Power Fail Input (PFI)
The power fail input is used to monitor the unregulated DC voltage or other
upstream voltage and to alert the system that a brownout or power failure is
imminent. When the PFI input is tripped, it can inform the system to start a
power-down routine in order to save important data before a reset output is
asserted. The power fail input has a threshold of 0.5V. By using a voltage divider
the user can monitor any upstream voltage. Connect PFI to V1 or GND if not used.

Power Fail Output (Active Low) - PFOB
The PFOB pin is an open drain, active low output. When the input voltage at PFI
is <0.5V, PFOB will be asserted.

Glitch Immunity at Voltage Inputs
The V1, V2, V3 and V4 inputs have a built-in glitch immunity feature that
prevents nuisance resets during normal operation. Noise and normal voltage
transients can cause these unwanted resets without some type of glitch
immunity. Figure 2 shows the combination of voltage overdrive and duration that
will not cause a reset for V1 and V2 inputs. Figure 3 shows the same data as
applied to the V3 and V4 inputs. Adding a small bypass capacitor to voltage
inputs can improve glitch rejection for very harsh environments.

Life Test
Life testing is conducted to determine if there are any fundamental reliability related
failure mechanism(s) present in the device.
These failure mechanisms can be divided roughly into four groups:
1. Process or die related failures, such as oxide-related defects, metalization-related
defects and diffusion-related defects.
2. Assembly-related defects such as chip mount wire bond or package-related
failures.
3. Design related defects.
4. Miscellaneous, undetermined or application-induced failures.
Life Test Results
As part of the Sipex design qualification program, the Engineering group had subjected
80 parts from each of 3 lots of SP6330 for a 1000 hour reliability life test at 125° C.
168 hour Life test
240 parts of SP6330 parts were subjected to the life test profile and completed
168hr the test without any part failures.

the parts again showed successfully completing the 500-hour life test without any
failures.
1000 hour Life test
The 240 parts of the SP6330 were reintroduced to the final phase of the test,
where the parts again successfully completed 1000-hour life test without any shift
on the process parameters.
FIT Rate Calculations
The FIT (failures in time) rate is the predicted number of failures per billion device-
hours. This predicted value is based upon the:
1. Life Test conditions (time and temperature, device quantity and number of failures)
are summarized under HTOL test table.
2. Activation Energy (Ea) of the potential failure modes.
The weighted Activation Energy, E, of observed failure mechanisms of Sipex products
a
has been determined to be 0.8 eV.
Based on the above criteria, the FIT rates at 25°, 55° and 70°C operation at both 60% and
90% confidence levels for the SP6330 product lines have been calculated and are listed
below.
